It's not 'like a dweeb'. It's cute. If there was ever a time Xander was just making chinhands, now is probably it. Seto's happy. He's happy for Seto. Things are going good for his friend, and Xander's just going to bask in that a little bit.

He's not out to draw attention to himself, honestly, but being nearly as tall as Seto normally, with the addition of wings that are a foot taller? Yeah, Xander is a little bad at hiding.
