You've only seen Aizawa this nervous a couple times in your entire life, so it's clear that something is seriously wrong now. He's pacing around the room quickly, glancing around constantly for something that you're not sure of.

"Hizashi," He says, his voice low and strained. "Can you help me with something?" His eyes are pleading, and he looks even more worn down than usual. After a moment, Hizashi rolls over and leaves you to sleep, getting up to go help Aizawa.
