At the end of Raw last night, right as Finn Balor was about to pin The Miz, the lights went out and Bray Wyatt appeared, hit Finn with a Sister Abigail, the lights went out again, and when they came back up, Bray was gone.
He teleported out of the arena, using his Spooky Magic Powers.
Bray Wyatt doesn't have any magic powers.
Spooky, or otherwise.
He was under the ring, and decided he didn't want to wait out there until after the dark segment was over.
I guess, when ya gotta go, ya gotta go.
