Nik returns to Wakefield after being ejected from his sisters wedding. Trying to find a missing puzzle piece sets in motion Nik's total recall of his brothers death, and the unit coping with his decline. 

Nik continues to look after his patients as his sanity slips further. Nik tries to piece together why his family lied about his brothers death. 

Receiving his promotion to Nursing Unit Manager Nik realises his love for Kareena is something much more then the last time they were together. 

James suffers a loss of identity as Tessa deals with her mother getting rid of all her things. Nik has a lot of unanswered questions over his brothers death when his mother shows up. 

Kareena suggests that distressing phenomenon Nik's experiencing; that he's observing himself from outside of his own body could be related to trauma from his past and we learn the person who died was a family member.

Memories of a flood enter Nik's mind as he tries to find the ring that once belonged to his mother. Discovering how much Kareena means to him Nik remembers he used the same ring to once propose. 

Raff's loyalty to Genevieve is seriously tested when her sexual desire runs rampant. Kareena's attraction to Nik is reawakened. And Nik inadvertently injures Tessa when he steps in to protect Linda.

James is running his finance business from the ward, Ivy is running from the screaming baby she can't bond with and when a song gets stuck in Nik's head, it triggers deeply buried memories he doesn't understand.
