[His jaw twitches. Sasuke doesn't understand what kind of concession it is from Qrow, to promise he'll answer messages eventually. That means something to Qrow; it's an acceptance of a connection between them, when he's been reluctant to offer such a thing to anyone in this world. For Qrow, that means he's always going to come back when he's needed, but the reverse is a bigger ask. And it feels a little bit a slap in the face after giving him more than he felt comfortable with already.]

Look kid, I'm not just looking at my watch waiting for messages all day. If I say I'll get to it, I'll get to it.

You want to think I'm dead because I haven't answered in a couple hours or something, fine, but that's underestimating me.
