Raph, in that grand tradition of people who aren't good with words but kind of touchy-feely anyway, smiles a bit at Red. She's almost cancelling out the chatter-box sitting next to her.

The chatter-box who had the exact same smirk as his brother Mikey when he was about to play a stupid prank on him. So Raph gives him the pinched, suspicious expression he saves for this kind of situation as he himself climbs out, nodding at the yetis in a noncommittal acknowledgement. They didn't seem bad, exactly, but Raph is still wary.

Not as wary as he is of Kon though.

"...What're you up to?"
