Nadia soon breaks into Joe's office and finds a key which leads her to the basement of an abandoned building where Joe has kept Marienne imprisoned in a glass cage.

However, Rhys is later revealed to be a figment of Joe's own imagination: Joe developed an obsessive interest in Rhys' life upon moving to London, finding commonalities between Rhys' rise from poverty and his own desire for moral redemption. Upon his kidnapping and imprisonment of Marienne Bellamy, Joe suffered a psychotic break that caused a rift in his identity, leading to recurring hallucinations of Rhys as a manifestation of his repressed, murderous impulses. Joe discovers this upon killing the real (innocent) Rhys in a blind rage. Joe's visions of Rhys persist despite this, and Joe attempts to expunge them by killing himself, seeing no other way to end his cycle of violence.

Phoebe rejects his proposal upon learning of his intentions from an obsessed fan who briefly kidnaps her, but suffers a downward spiral of PTSD in the following days and returns to Adam for solace. Adam takes advantage of Phoebe's declining mental state and hastily marries her, but Phoebe experiences a nervous breakdown at her wedding and is hospitalized.
