#1 Bo Dallas stops the madness
What if this feud gets so ridiculous that after a series of zany twists and turns which resembles a Road Runner and Wile E. Coyote cartoon someone who knows Bray Wyatt well can't take enough of it.
Although, Bo Dallas is Bray Wyatt's real-life brother, it's never been mentioned on television. Some fans have wondered if WWE would ever get the Rotunda Brothers together on television and this would be a great chance for that to happen.
As one more layer of goofiness is added to this feud where Bray Wyatt casts the soul of a sheep into Finn Balor or something like that the lights could go dark. A spotlight would then shine on the stage and Bo Dallas would emerge with a microphone yelling, "Windham, what are you doing?!" (In case you didn't know Bray Wyatt's real name is Windham Lawrence Rotunda.)
Wyatt would stop what he was doing and look at his real-life brother and say, "I have no idea, Taylor." (Bo Dallas' real name is Taylor Michael Rotunda)
After the two Rotunda Brothers looked at each other for a second and Finn Balor leaves the ring somehow free of the sheep soul which used to inhabit him. Then Bray could just leave the ring and walk off with his brother.
After this, they would be known as their real names Windham and Taylor and the Rotunda Brothers would be a tag team worth paying attention to.
An ending like this would be surreal and totally breach the 4th wall to reveal the fact that these guys realize it's all ridiculous if it got to some plateau of zaniness. But hasn't the entire Bray Wyatt story been like some grand surreal adventure in the first place? For crying out loud he turned the ring at WrestleMania 33 into worms and cockroaches.
Having Wyatt totally break kayfabe and just walk off to form a new team with his brother would not only provide a new chapter in Bray Wyatt's career but also revitalize Bo Dallas in amazing ways. They've already tagged together before so it wouldn't be a foreign concept to them either.
Of course, it could also have negative ramifications on the business as a whole where people will start to poke even more holes in the logic behind WWE storylines. So it might be a good idea to just forget this one.
