Of all the things to complain about...Quoting Skitch (view post)
Didn't Ghost Protocol make it clear there was closure? In the sense that they couldn't see each other again because then she'd be a target again.
I'm willing to entertain the notion that perhaps there's something I'm missing here and that it might have warranted a few lines of dialogue in Rogue Nation, but still not the kinda complaint I expected from anyone.
