"Bookworm?" Casey asked, eyeing Sebastian as the other closed his eyes, seemed almost to fall asleep right there. The clatter of the bat loud, as Casey watched the other teen for a moment, frown on his face.

Not an unhappy-or-upset-with-Sebastian frown either. A concerned one. "Bookworm? Sebastian..." Moving to pick up the baseball bat, putting it away in its holster at his back. "You've been seeing things too, huh? You alright?" No more playful teasing in the voice; genuine concern.

Casey was a vigilante for a few reasons; one of which WAS helping others. Especially those who couldn't help themselves. (It was a minor reason, compared to wanting to kick the scum out of his city, but it was still there.)
