Five had barely turned back towards him, with genuine interest in what he's about to say, when the roof snaps. They both have seconds to know what's coming, but in the time it takes for him to try to grab hold of the other man, the rotted structure under their feet gives way.

The second teleport is sloppy. He pulls them mid-fall through the floor beneath before they can feel its impact, and winds up sprawled on his back the next level down. Dust and dirt fall around them, and he's content to let it. He looks up at the ceiling, watching it rattle like an earthquake as the collapsed pieces fall into the hole they created above. If anyone was sleeping, that probably woke them.

He belatedly turns his head to locate Wei Wuxian to see how he managed. Then just after he thinks it stopped, he hears one final distant crash. Either from the roof, or they managed to knock over a lamp somewhere.

Okay. So this one might be on him.
