Yeah, honestly he has to agree, albeit mostly because he's a criminal mastermind which is probably not Will's reasoning.

But hey, no need to get into details. It's true - Chrollo has literally never put on anything plaid. In fact, offhand he can't remember ever having met someone who did, at least not before coming here. He'd never even thought about plaid. Maybe plaid is just Not A Thing where he comes from - which just raises the question of why it's a thing anywhere, but he's not going to bring that up, it's rude.

"Ever! I guess most of the time I usually--" ooops Will may have missed the tug but Chrollo did not. "Whoa!" ...the only problem is, no idea how to reel it in. He gives Will a sort of mildly panicked look that says, What now!
