Gajeel briefly considers whether he could just beat up all these people at once. He's pretty sure he could if none of them have any powers, maybe even if some do.

But that might be admitting that Chris is seriously getting to him, and no way is he doing that. So instead he sits back on the bench and decides to just annoy them back. In addition to his previous glaring and growling, he starts trying to kick anyone who gets close enough, as well as occasionally peeling bits of paint off the bench and flicking them at people. Mostly at Chris.
