Pit's been fighting almost non-stop since he left his apartment earlier today. He had only stopped once, and that was to die.

He got better, though! But his fighting partner wasn't too pleased with him... Which is why he's fighting extra hard to make sure she doesn't get hurt and doesn't have to overexert herself because WOW does he feel guilty exploiting his angel powers only to freak someone out. The problem with fighting extra hard, though, is that he's been dashing and dodging a lot, without keeping an eye on his stamina.

Which means he's suddenly stopped to catch his breath.

Leaving him completely vulnerable to the stronger monsters.
