[Well, it might cause problems if they hang around too long, but Ren can understand not wanting to risk it. Given that, though, he turns towards the edge of the room nearest them, gesturing for Emil to follow as he starts heading in that direction. While Ren isn't built for physical exertion, he is skinny and long-legged, which means he's absolutely fine for speed when he needs to be.]

We'd better be quick about it, then...I don't really like the look of that. [He nods towards the middle of the room, where there's a visible downwards pitch to a section of the roof, the shape of it visible through the smoke. It's holding for now, but that could change at any time.] Hopefully if we find anyone, they're not under green...

[He's seen a few green shields here and there, but most of them seem to be purple dusk or lower, which is a whole lot more useful for him even if he does have a Breaker. If the Breaker can't shatter a green shield in a single shot, reloading would waste a great deal of time they don't really have.]
