Hey, that's a good sign! The kid's already coming outta his shell. Whew. After all of Goro's warnings, he wasn't sure how well he'd stick the landing. At the older Akira's advice, he does a silly little bow.

"Understood, Sensei." But, oh? A missing card? There's probably a trick to this. A pun in the making. He tries striking the Akechi Pose™, chin in hand, giving an exaggerated 'hmmmm.' "Is it the Joker?" Or maybe that's too obvious. "The Ace?" Because he's an ace with these tricks? Ace of Hearts would be on point for a Phantom Thief, too. So many options. So many potential punchlines... "Or maybe it's a calling card."

Maybe too on the nose, but it had to be said.
