Chloe to be revealed as an antagonist to Jack, she will come down on the side of the Edward snowden baddy, Jack will end up killing her.
Nah, Chloe will be conflicted, but she'll come good.
Jack needs a slap though for chatting to Audrey on the phone when he should have been protecting a device that will give the baddies (or goodies depending on your outlook) control over the US's satellites, nukes and whatever else.
Was a bit surprised when Jack threw Margot out of the window, although everyone in the US & British secret services seems fairly relaxed about it all really.
Imagine if he'd bitten her on the shoulder though!! There'd be outrage
