The mysterious Sister Abigail character has been referenced by Bray Wyatt on WWE programming for a few years now, but he has always referred to her in the past tense and has even hinted that she may have passed away.
However, with the recent reformation of the new Wyatt Family with Bray Wyatt, Luke Harper and Braun Strowman, there is now talk going on backstage about possibly debuting the Sister Abigail character on television.
No word on who would play the character.
