Always knew he was.
He showed his true colours right in the beginning when during the so-called 'love triangle'.
He was all me, me, me, bitch, bitch, bitch, stab, stab, stab.
Plus he's always around when there's a bitching session going on stabs the person in the back then sucks up to them 5 minutes later!
Quite how Alex could suck-face with him God alone knows!
