Having the mask shoved back at him, Zuko didn't bother to look at it cause wow that sure is a lot of hair you have there Toph. Zuko just stares for several moments as he watches her manipulate it into a braid. Hairbending? Anyway, he's actually kind of surprised. He's never seen her with her hair other than her usual bun. And really the braid is not a bad look for her at all.

With the guy being mentioned, he looks back over in the direction of the trash cans. Yep still there.

"Okay I-wait what did you do to my mask?!"

He finally noticed.
