Joker might regret using those words. As soon as he calls Strange a professional, Strange's eyes light up and a small, self-satisfied little smile is planted firmly on his face. Yes, he knows he's a professional. And yes, he knows he's one of the best magicians in the carnival (at least, so thinks captain ego). But man, just hearing someone else say this is a boost to his morale.

"You were good enough to make those little cufflink trinkets," Strange points out, describing that teleportation spell that Joker cast ages ago. "I'm certain you'll be able to figure this magic out. And if not, perhaps I'll call together another meeting of the carnival's magicians to help or offer advice!"

Welcome to magic club, Joker.
