Mmm, there's probably lights somewhere else...maybe we just got unlucky. [Taking Allura's cue, Ren pulls his own watch out of his pocket and pokes around with it a bit, turning it on so the still pathetically limited light pool is enhanced a little bit.]

I was already looking for a way out when I came in here...and I think I came from that way? [He gestures with his watch light in the direction he's currently facing, which is in turn the opposite to what it was when Allura initially walked into him.] So there must be a door back that way.
