Stiles keeps walking, moving to shove his hands in his pockets, to keep them from flailing about. He knows Derek is right, that he has a point, but Stiles feels nearly bad for not actually joining him in research. He just wouldn't be any good right now, and he figures Derek probably wants time to decompress alone, without Stiles underfoot.

The campus is in sight, meaning that they are nearly done with their little walk, here. "Thanks. I'll keep doing some talking, see if anyone found out anything new." Because Stiles is more likely to talk to people than Derek.
