I'm too human. We are essentially creatures of instinct, passing whims, really our most profound moments. I can't let you have her I'm afraid. She really does love you, you know.
~ Foster to Freddie before murdering him.
I think I do. You're nothing. You don't deserve that girl, and you know...I do.
~ Doctor Foster taunting Cook before attempting to murder him.
(Cook: Mr. Foster....) Dr. Foster, please.
~ Doctor Foster introducing himself to Cook in their confrontation.

Dr. John T. Foster is the main antagonist in the fourth season of the E4 TV series Skins.

He was Effy Stonem's psychiatrist and was pretending to treat her from her mental illness when really he was using her and manipulating her mind with false medication due to his lust and desire for her.

He was portrayed by Hugo Speer.


Dr. Foster is a psychiatrist who attempts to rehabilitate Effy after her suicide attempt. He eventually develops an obsessional crush on Effy and tries to make her fall for him, by any means necessary. Foster steadily makes Effy's mental issues worse in order to rebuild her for his own image, alienating her from her mother and Freddie in the process.

Freddie eventually finds out about Foster's secret and as a result, Foster murders him with a baseball bat. All of Freddie's friends and family are worried upon his disappearance along with Cook and they decided to throw a party in his honour despite this Foster wrote a fabricated note saying he had fled the country, nobody believed this however as it was something Freddie would never think of doing. That night however James Cook spots Foster walking past Freddie's house looking on as if he was proud of something.

Convinced he had the found the cause of his missing friend, he follows Foster home and sneaks into his basement. In the basement Cook finds Freddie's bloody clothes in his washing machine and is ambushed by Foster. Cook questions what he has done and Foster reveals his intentions with Effy and then tells Cook to kneel down as he tries to murder him before rapidly taunting him regarding him as a waste of a human being. However Cook, stalls him and surprisingly agrees before telling him that he should know that he let of his wrath for murdering his friend and as a result an enraged Cook manages to fight back and kill Foster for revenge and breaks the news of the truth behind Freddie's disappearance to the others, this only fuelled everything that everyone viewed Cook as and painted him as a monster in his own eyes as he becomes a fugitive and forever lives with the guilt of killing him despite what he had previously done.


  • He is easily the most evil character in Skins, and the only one to be Pure Evil. Of course, it is debatable if Louie and James Cook. Sr are also Pure Evil, as they are no different than Dr. Foster.
