Spoiler Warning: This article contains major spoilers for all six episodes of Netflix’s Behind Her Eyes and discusses important differences from Sarah Pinborough’s original novel.
Rob had everything he claimed to want.
He had escaped rehabilitation. He had found a friend who genuinely cared about him. And Adele had welcomed him into a world of wealth and comfort that seemed almost unimaginable compared with his previous life.
Then he murdered her.
In the final episode of Netflix’s Behind Her Eyes, viewers discover that Rob used astral projection to exchange consciousness with Adele before killing her in his own body.
He stole her identity, her fortune, and her relationship with David.
For years, the person everyone believed was Adele was actually Rob.
But this revelation raises a question that is more interesting than the body-swapping mechanism itself.
Why did Rob betray the one person who had treated him with genuine kindness?
Was he desperate to escape poverty and addiction?
Did he want Adele’s beautiful home and privileged lifestyle?
Or was the entire crime motivated by his obsession with David?
The answer becomes clearer when we compare the Netflix series with Sarah Pinborough’s novel—and examine the clues viewers noticed after learning the truth.
Why Did Rob Want Adele’s Life?
When Rob first meets Adele in rehabilitation, their circumstances are dramatically different.
Rob is a recovering heroin addict from a troubled working-class background.
He feels disconnected from his family and has little confidence that his life will improve.
Adele, meanwhile, comes from a wealthy family.
She has inherited an extraordinary estate after the deaths of her parents.
Although she has experienced profound trauma, she possesses the kind of financial security Rob has never known.
The two become close friends.
Adele helps Rob understand lucid dreaming and eventually astral projection.
She trusts him enough to invite him into her home.
For Rob, the experience is overwhelming.
He sees a beautiful house, an apparently perfect relationship, and a future completely unlike his own.
The temptation is obvious.
But wanting another person’s lifestyle is not the same as deciding to murder them.
Something changes when Rob meets David.
The Moment Rob Meets David Changes Everything
David is Adele’s fiancé.
When Rob arrives at Adele’s estate, he finally meets the man she has spoken about so affectionately.
His reaction is revealing.
Rob becomes unusually quiet and visibly fascinated.
In the kitchen, his behavior around David suggests an attraction that he does not openly acknowledge.
Viewers discussing the scene on Reddit have pointed to Rob’s expression, his awkwardness, and the way his attention shifts toward David.
These moments are subtle on a first viewing.
After the finale, they become important clues.
Rob is no longer simply fascinated by Adele’s life.
He is fascinated by the person at the center of it.
David represents affection, stability, and a relationship Rob desperately wants for himself.
Adele already has that relationship.
And Rob discovers that, through astral projection, he may be able to take her place.
Adele’s wealth makes her life desirable. David makes stealing that life emotionally irresistible to Rob.
Was Rob in Love With Adele or David?
This is one of the questions that has generated debate among viewers.
Rob’s journal and early interactions suggest that he is deeply attached to Adele.
He admires her.
He values her friendship.
He appears captivated by her kindness and privileged life.
That attachment can initially look romantic.
In a Reddit thread titled Why Rob?, one viewer questioned why Rob would abandon Adele for David when his feelings toward Adele seemed so intense.
Other commenters pointed to the kitchen scene as evidence that Rob becomes attracted to David almost immediately.
Both observations identify something important.
Rob’s feelings toward Adele are complicated.
He admires her life and enjoys being close to her.
But the final revelation suggests that his desire to possess her life becomes stronger than his attachment to her as a person.
The novel makes the distinction clearer.
In Sarah Pinborough’s original story, Rob’s desire for David is more explicitly central to his decision to steal Adele’s body.
The television adaptation places greater emphasis on Rob’s fascination with Adele’s wealth and lifestyle as well.
That difference explains why some viewers interpret the crime as a mixture of romantic obsession and social envy.
The two motives are not mutually exclusive.
Rob can desire David while also envying the advantages Adele possesses.
What matters is how he acts on those desires.
He decides that Adele herself is expendable.
Why Did Rob Kill Adele Instead of Simply Swapping Back?
The mechanics of the first body swap reveal how deliberate the crime is.
Adele teaches Rob how to use astral projection.
The ability allows a person’s consciousness to leave the body and travel elsewhere.
Eventually, Rob persuades Adele to attempt something more dangerous.
They exchange bodies.
Adele’s consciousness enters Rob’s body.
Rob’s consciousness enters Adele’s.
For a brief moment, each experiences life from the other’s physical perspective.
But Rob has no intention of returning.
He uses heroin to incapacitate and kill his former body while Adele’s consciousness is trapped inside it.
He then disposes of the body in a well on the estate.
This is not an accidental consequence of experimenting with astral projection.
Rob deliberately makes the exchange permanent.
As long as Adele remains alive in his former body, there is a possibility that she could expose him or reverse the deception.
By killing her, he removes that possibility.
He does not merely steal Adele’s appearance.
He eliminates the person who could prove the theft.
That is why the crime is so horrifying.
Adele trusts Rob because she believes they are sharing an extraordinary experience.
Rob exploits that trust to murder her.
Did Rob Also Want Adele’s Money?
Yes, Adele’s wealth is clearly part of what attracts Rob to her world in the Netflix adaptation.
He is fascinated by the estate and the lifestyle she enjoys.
But money alone does not explain the entire plot.
If financial security were his only objective, stealing Adele’s body would already have achieved it.
He could have enjoyed her inheritance and avoided further risks.
Instead, he spends years trying to keep David emotionally attached to him.
When David eventually falls in love with Louise, Rob becomes willing to abandon Adele’s wealthy identity.
That decision is crucial.
He gives up the very body and lifestyle he originally stole.
Why?
Because David no longer loves the woman he believes is Adele.
He loves Louise.
Rob therefore decides to become Louise.
The second body swap reveals the priority that remains constant: David.
Wealth helps explain the initial attraction to Adele’s life.
But Rob’s later actions show that possessing David matters more than preserving the privileges attached to Adele’s identity.
Why Didn’t Rob Simply Try to Win David’s Love?
Because David was in love with Adele.
Rob could not simply replace her in David’s affections by declaring his feelings.
David’s romantic interest was directed toward Adele, not Rob.
The body-swapping ability offered a grotesque shortcut.
Instead of persuading David to love him as Rob, he could become the person David already loved.
This is the fundamental deception behind the story.
Rob wants the benefits of a relationship without allowing David to choose his partner freely.
David believes he is marrying Adele.
In reality, Adele is dead.
The person sharing his life has taken her identity without his knowledge or consent.
Rob’s desire for David is not itself the horror.
The horror is his decision to murder someone and impersonate her to obtain a relationship.
His actions turn affection into possession.
He does not accept that David is a separate person with the right to choose whom he loves.
Instead, he treats David’s love as something that can be captured by controlling the body of the person receiving it.
Why Did Rob’s Marriage to David Fail?
Rob succeeds in taking Adele’s place.
But he discovers that possessing her body is not enough to reproduce her relationship.
David begins to notice that his wife has changed.
Her personality is different.
Her behavior becomes increasingly manipulative.
She appears capable of learning things she should not know.
And the relationship gradually deteriorates.
Rob also uses the secret surrounding his former body’s death to keep David trapped.
David helped conceal what he believed was Rob’s overdose.
That involvement gives Rob leverage.
He can make David fear the consequences of exposing the past.
But coercion cannot restore the affection David once felt for Adele.
The marriage becomes a prison for both of them.
David wants to leave.
Rob refuses to let him go.
This is the central failure of Rob’s original plan.
He believed that taking Adele’s identity would give him Adele’s love story.
But a relationship is not contained inside a body.
It depends on personality, trust, shared experience, and the continuing choices of two people.
Rob can imitate Adele’s appearance.
He cannot become the person David originally loved.

Why Did Rob Steal Louise’s Body Next?
Louise creates a new problem for Rob.
David falls in love with her.
At first, Rob tries to manipulate Louise through friendship.
Living as Adele, he introduces Louise to lucid dreaming and provides Rob’s old journal.
He encourages Louise to distrust David while making himself appear vulnerable.
The strategy allows Rob to influence Louise and monitor the developing relationship.
But David eventually decides to escape the marriage.
He is prepared to reveal the truth about the body in the well.
Rob realizes that his hold over David is collapsing.
Then he sees another opportunity.
Louise has learned to astral project.
She trusts the woman she believes is Adele.
And David loves her.
Rob arranges a staged emergency involving a fire and a heroin overdose.
When Louise projects her consciousness into the house, Rob uses the opportunity to exchange bodies with her.
Louise becomes trapped in Adele’s drugged body.
Rob enters Louise’s body.
He then kills Louise and assumes her identity.
The second crime follows the logic of the first.
When the person David loves changes, Rob changes bodies to follow his affection.
It is an escalating pattern of impersonation and murder.
And it reveals why the first crime was never enough.
Rob does not merely want to be loved.
He wants to control who receives David’s love.
Was Rob’s Entire Plan Carefully Designed From the Beginning?
Not necessarily.
The series establishes that Rob deliberately arranged both body swaps.
But that does not mean he anticipated every development years in advance.
When he first steals Adele’s body, Louise is not part of his life.
He cannot know that David will eventually fall in love with her.
The second body swap is therefore better understood as an adaptation to a changing situation.
Rob recognizes that his original strategy has failed.
David no longer wants Adele.
Rather than accepting that loss, he constructs a new plan around Louise.
This distinction matters because some viewers interpret Rob as an almost all-knowing mastermind.
He is certainly manipulative.
He understands how to exploit trust.
He uses astral projection to gather information and control situations.
But he also makes decisions driven by jealousy and fear of abandonment.
A Reddit discussion titled I don’t fully understand Rob’s plan explored whether his behavior toward Louise was contradictory.
Why encourage Louise to distrust David if the ultimate goal was to become Louise and marry him?
One plausible explanation is that Rob’s strategy changed as the relationship developed.
Initially, he may have wanted to separate Louise from David.
Later, he realized that Louise’s body offered a new way to remain with him.
The series supports this evolving-plan interpretation more strongly than the idea that Rob had designed every step from the beginning.
Did Rob Ever Truly Care About Adele?
Rob’s friendship with Adele appears meaningful in the early episodes.
She offers him companionship and kindness when he is struggling.
He admires her and enjoys being part of her world.
But his eventual betrayal reveals a profound limit to that attachment.
Whatever affection he felt was not enough to stop him from sacrificing her.
This creates two possible interpretations.
One is that Rob’s friendship was always primarily self-interested.
He wanted access to Adele’s wealth, lifestyle, and relationship.
The other is that he initially cared about her but allowed envy and obsession to overwhelm that attachment.
The series does not provide a definitive account of every stage of Rob’s emotional development.
However, the second interpretation makes the betrayal particularly tragic.
Adele may have genuinely changed Rob’s life for the better.
She helped him develop an extraordinary ability.
She invited him into her home.
She treated him as someone worthy of friendship.
And Rob used those gifts to destroy her.
His betrayal is not merely an act of violence.
It is a corruption of the trust that made the friendship possible.
The Novel vs. Netflix: Which Motive Is Stronger?
The original novel and television adaptation share the same fundamental revelation.
Rob murders Adele by stealing her body and later repeats the deception with Louise.
But they place different emphasis on his motivation.
In discussions comparing the two versions, readers have noted that the novel presents Rob’s desire for David more directly.
His attraction to David becomes central to the explanation of why he wants Adele’s identity.
The Netflix adaptation makes Rob’s fascination with Adele’s privileged world more prominent.
His admiration for her house and lifestyle adds another layer to his motivations.
This difference changes the way viewers interpret his betrayal.
In the novel, the crime can be read more directly as an attempt to possess David.
In the series, it also becomes a story about envy and the desire to escape one’s own life.
Neither interpretation excuses Rob’s actions.
The distinction is useful because it explains why viewers disagree about what Rob really wanted.
Some see a character driven primarily by romantic obsession.
Others see someone who wants another person’s entire existence.
The strongest interpretation of the television version combines both.
Rob wants David.
But he also wants to stop being Rob.
Adele’s body offers the means to accomplish both.
The Most Revealing Detail: Rob Gives Up Adele’s Life
The decisive evidence comes at the end.
After years of living as Adele, Rob abandons her body.
He gives up the estate, the identity, and the financial security he once envied.
He does so because David has fallen in love with Louise.
This decision exposes the weakness of the theory that Rob was motivated only by wealth.
If money were his overriding objective, the second swap would make little sense.
But if David is the central object of his obsession, the decision becomes consistent.
Rob is willing to inhabit whichever body allows him to remain close to David.
Adele is useful until David stops loving her.
Louise becomes useful when David falls in love with her.
The bodies are interchangeable to Rob.
The person he wants is not.
That is why the second murder is so important to understanding the first.
It reveals the motive that survives every change in circumstance.
What Rob’s Obsession Says About Identity
Behind Her Eyes presents identity as something that can be physically stolen.
Through astral projection, consciousness can move from one body to another.
But the series also demonstrates that identity is more complicated than appearance.
Rob takes Adele’s body but cannot sustain Adele’s marriage.
He takes Louise’s body but immediately struggles to imitate her relationship with Adam.
The boy notices that his mother has suddenly changed her opinion about boats.
It is a small detail.
But it exposes a fundamental flaw in Rob’s strategy.
He can occupy a body without possessing the memories and relationships that define the person who lived in it.
Rob repeatedly confuses ownership with intimacy.
He believes that if he can become the person David loves, he can claim that love for himself.
Yet his experience as Adele proves that the deception cannot produce a genuine relationship.
David eventually falls out of love with the person he believes is his wife.
And after Rob steals Louise’s body, the same problem threatens to emerge again.
Adam already senses the difference.

Final Verdict: Why Did Rob Steal Adele’s Body?
Rob stole Adele’s body because he wanted the life she possessed—especially her relationship with David.
Adele’s wealth, beauty, and privileged lifestyle made her existence attractive to him.
But his fascination with David transformed envy into a murderous obsession.
He used the astral projection technique Adele had taught him to exchange bodies.
Then he killed Adele while she was trapped in his original body.
For years, he impersonated her and remained married to David.
When David stopped loving the woman he believed was Adele, Rob repeated the crime with Louise.
That second murder reveals the deeper truth.
Rob did not simply want Adele’s money.
He wanted to occupy the place of the person David loved.
And when that person changed, Rob was willing to kill again.
Rob’s greatest obsession was not becoming Adele. It was becoming whoever David would love.
That is the tragedy at the heart of Behind Her Eyes.
Adele gave Rob friendship.
He repaid her by stealing her life.
And even after succeeding, he discovered that a stolen identity could never guarantee the love he wanted.
