[ caroline says that part fairly matter-of-factly. she'd been annoyed by it at first, even her own young instincts easily relient on that get-out-of-jail-free card when trouble kicked up, but by now caroline was used to it. she doesn't tell him that compulsion comes back to her in her dreams — mostly because she doesn't want to talk about her dreams with klaus mikaelson right now.

You can't compel anyone. And you can't just go around biting into people, because you'll get caught. There's cameras everywhere, and where there aren't cameras, there are implant scanners.

[ and, for the first time, caroline realizes this... isn't the same klaus she knew before. because if he was, he'd know this. he wouldn't be surprised that he couldn't compel anyone. he'd be asking her where damon was, he'd be asking after clarke... he wouldn't be having this conversation.

You don't remember being here before, do you?
