WHY is Julian so far up Julie's arse? (sorry, crude I know, but true!) He's one that she confides in and slags the others off to. If he had any backbone or decency he'd pull her up on it.
I think he's sharp and witty, but he's letting himself down by being such a wimp. He should just tell her how nasty she's coming across instead of just sitting there.
"Don't gang up on her, guys." Um, what?! Nobody's ganging up on her, she's doing a pretty good job of alienating everyone all by herself!
