#4 Definitely leading to a feud with a WWE Hall of Famer
There has to be a point to the pattern, in my opinion. We know that Bray Wyatt changed up his finisher to the Mandible Claw because everyone can take it with ease. A lot of WWE Hall of Famers would not necessarily be able to take Sister Abigail.
But from the way that things seem to be piling up, it is quite clear that Wyatt is going to head into a feud with a WWE Hall of Famer, someone ideally with a dark gimmick like Sting. This will be his coronation, the ultimate passing of the torch from the previous generation to the new one, making Wyatt for true greatness.
It could also lead to a feud with a WWE legend like The Undertaker or Kane. Everyone wants to see the forces of darkness collide, down the line.
