Oh, so it is a 'for love of god, why' situation. Gabriel isn't sure if he's dismayed or impressed, or if this is any less weird than it would've been if it were skin, but Catra's assessment of 'gross' really does say it all.

He takes the thermos reflexively when she shoves it at him, though he does almost immediately put it back on the table because one: he doesn't want to keep touching it, and two: he also needs to look for more terrible merchandise. He's begun digging through a pile of what he thinks might be furry headbands when Catra starts talking about vampire teeth, and gives it a moment of contemplation.

"Bet people would stud their jackets with them instead of metal spikes." Yes this is his first thought of a use for vampire teeth aside from necklaces, which Catra has already mentioned. "But the real question is if the teeth just fall out on their own like shark teeth, or if they'd have to be ripped out."
