Kol's pretty certain that even if Allie swapped lives with Cassandra, it'd still turn out the same. As emotionally immature as he often presents himself to be, he at least realises that. Nik has his issues, along with Rebekah and the impeccable Elijah; even if they were like him, they'd still be littered with problems. The first is obvious: none of them could ever be as perfect as him.

What would he do if he lost something from one of his siblings? Although Kol can hardly remember the last time any of them gave him something, he knows he'd be upset if someone took the book Rebekah bought him one Christmas or the stupid toy Nik had given him when they were kids. He'd do anything to get them back—even wreck the world.

It doesn't seem like Allie has chosen to wreck the world for it. Instead, it looks like she's just chosen to go to the beach to inform it of how she secretly feels—quite possibly not strong if he's to assume anything.

He looks down, but it's not necessarily in an effort to give her privacy. Perhaps he's seen it! (He hasn't.) "What does it look like?"
