#3 The characters parted amicably
During the 2016 brand split, Braun Strowman was drafted away from the Wyatt Family over to Raw and that was that. Bray Wyatt would replace him with Randy Orton and Braun would begin his own journey.
There have been some interesting developments recently on Twitter between the two former Wyatt family members.
In response to news that Bray Wyatt would be facing the winner of Strowman/Rollins, Braun had this to say:
As you can see, he's still acknowledging Wyatt as his teacher. It could be a hint at his allegiance. Bray responded to Braun's threat by referring to him as "baby boy," the same term he used for Rowan.
Teaming up with The Fiend could help eliminate some of the light-hearted elements we've seen arise in The Monster Among Men and help take the character to a darkness we've yet to see materialize from him.
