Something that's an absolute must upon Rowan's return, is to have him confront the man who replaced him in The Wyatt Family. When Erick Rowan suffered a torn bicep in June, it seemed like he'd be out of action indefinitely. That's exactly why the writing staff took the decision to replace him with Braun Strowman, who had been working in the NXT developmental system. During many of his appearances since joining Bray Wyatt and Luke Harper in August, Strowman has worn a black sheep mask. This contrasts mightily with the white sheep mask worn by Rowan regularly. There's a story there just begging to be explored, especially when Bray refers to Braun as 'Sister Abigail's Black Sheep'. There's intrigue into exactly what this means, and it could play a pivotal role in any forthcoming feud. It makes sense that Rowan would be upset over being replaced, and he'd look to eliminate Braun Strowman. This could be something Wyatt himself could encourage, interested to see which man would be left standing.
