[Ren tilts his head a little at the seeming indecisiveness (or, more likely, an attempt to make it sound like he's less worried than he is). He does give a slight smile at the attempt at a joke, though, his own tone brightening up a little accordingly.]

Well, I already handled that for the people I know...though I think some of them were already moved. It's kind of hard to tell when things are like this right now.

[He certainly hopes they were moved, because some of the people unaccounted for are extremely important to him - he hasn't found Aichi yet, among others, and while he doesn't want to hope too much that they're awake in case he's disappointed, he can't entirely quash the thought that at least one of them might be.]

Make sure you put them somewhere you can easily remember when you find them. It'll make things way easier later.
