Erwin doesn't let go, though it's more out of surprise -- he hadn't realized everywhere the stickiness had gotten to Levi, but once he's taken care of his face, he'll gently wipe off his hands. Levi has nice hands, he thinks. They're small but clever - and strong, as he's realizing.

But once his hands are clean, he seems much calmer. That's good, at least, and Erwin just nods cheerfully, and wipes his own hands off on the handkerchief before folding it over and stashing it back in his pocket.

"You're welcome, Levi."

He looks around, picking up his jar again.

"Do you want to catch more fireflies?"
