[Cook has discovered John Foster has killed Freddie. Dramatic music plays]

Cook: I don't think you know what I am, mate.

John Foster: I think I do. You're nothing. [Cook nods sarcastically] You don't deserve that girl. And you know... I do.

Cook: [mockingly] I'm a fucking waste of space. I'm just a stupid kid. I got no sense. A criminal. I'm no fucking use, me. I am nothing. So, please... Please... Get it into, you know, into your bonce... that you killed my friend. And... [shrugs] I'm Cook. [John Foster smiles] I'M COOK! [throws a punch. Series ends]
