"Not from you," he replies. Sure, maybe say that the rift is a risk-- or at least, an annoyance, because though he knows it could harm him, he's skeptical that it could actually kill him-- but Rush? Little human Rush, with all his pride and bravado, playing up his own nonchalance like he's going for an Oscar.

And when Rush finally acquiesces, he crouches down in front of him so that they're closer to eye level.

"Oh thank you so very much," he says, his voice is dry enough to desiccate oceans. "It's so very kind of you. I'll be waiting with bated breath."

He seems to consider things for a moment, idly tilting his head back and forth like he's weighing one option versus another, and then snaps his fingers. He disappears immediately after-- no reason to stick around now that his objective is fulfilled.

Rush's legs are functional again, but Lucifer didn't fix the ache in his hand.
