[Ren nods a little, taking a few more seconds before he stands upright properly again. As he does, he reaches up to untie the coat from around his mouth and nose, since that's what he's been using as a makeshift mask by this point.]

I don't know, I don't really want to be wearing my coat in there even if you did find a cloth...it's probably thicker, too. [Even if it is a makeshift solution, it's probably an okay one to be getting on with.] I'll see what I can find on my way around, though. More people are probably here to help by now, right?
