Just watched Raw is Snowstorm and I'm not sure what they wanted to accomplish with that. Bryan basically mocking Reigns and saying that he needed The Rock and the WWE spoonfeeding him to get where he is. How do they think that gets Reigns over as a face?
Maybe I'm just the biggest Bryan mark right now, but this felt not like writing Bryan out of the picture. Especially after him saying that he wants to end this deal with Kane on Thursday and becoming WWE Champion again. This felt so weird, and I need to see next week to make something out of this. I don't think the WM main event is as set in stone as everyone thinks it is.
I see two possibilities
1) Heyman joins forces with Reigns and turns on Lesnar, turning Lesnar fully face & Reigns heel at WM.
2) Lesnar states he is leaving after WM regardless of whether he wins or loses. Everyone assumes Reigns will win, but Lesnar destroys Reigns. Cut to RAW the next night; Lesnar wants to walk off as undisputed champion, cue Bryan wanting his rematch for the belt he never lost. Bryan vs Lesnar becomes the Main Event of RAW - Bryan is about to win, but cue Reigns interference. Takes out Bryan, spears Lesnar. In walks Rollins, who cashes in MitB on Lesnar, and Heyman joins Rollins and Reigns.
Your new "Authority" is Rollins as the champ, Reigns as the heel muscle (instead of Big Show and Kane), with J&J security and Heyman. Assuming Sting beating HHH ends the "Authority" gimmick.
Lesnar leaves, having never been beat. Bryan gets his match against Lesnar and is set up to have beaten the Beast, but Reigns denies him the opportunity out of jealousy. He is set up to protect Rollins, and Heyman can talk for Reigns as need be. Lesnar has two ready set feuds should he come back, and you can cue Bryan chasing Rollins for the belt.
