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.
You don't deserve that girl but I do!
~ Doctor Foster before attempting to murder Cook.

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 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. James Cook later finds Freddie's bloody clothes in his basement and is ambushed by Foster. Foster reveals his intentions with Effy and tries to murder Cook as well. However, enraged for what he did to Freddie and Effy, Cook manages to fight back and kill Foster for revenge and as a result, Cook becomes a fugitive.
