The demons do look at Setsuna warily for a second. They will heal him, but touching an angel? Not their most favorite thing in the world.

Setsuna shakes his head and puts out a hand, "It's okay. I don't need them to." He might be a little weak on his feet, but he still lets his wings rip out from his back - the shirt he's in is already in tatters anyway.

"I'll heal. Let them heal you," he tells Negan.
