Idea from a guy on Reddit:
Since turning his back on The Shield, Seth Rollins has made it more than a catchphrase by remaining the RIGHT NOW of WWE. This is why WrestleMania 31 must end with HIM.
I want Paul Heyman to poker face Lesnar's broken rib while secretly knowing it weakens his client. Forcing him to seek enterprise elsewhere.
Subtly, it appears throughout the build that Paul Heyman MIGHT be in the ear of both Roman Reigns and Seth Rollins.
A Superman punch and/or a Spear CANNOT logically take down Brock Lesnar. Something emphatic must psychologically take Lesnar out of the match. Paul Heyman's betrayal.
Betrayal indeed takes place at WrestleMania and it merely appears that Roman Reigns has aligned himself with Paul Heyman. However, the REAL swerve is that of Seth Rollins who ambushes Reigns and becomes WHC.
The storytelling doesn't stop there. Seth Rollins reveals that he is actually not aligned with Paul Heyman by refusing any future services from him. Seth simply used him to get
what he wanted. Something a TRUE ARCHITECT would do.
Alone is Paul Heyman, who thought he was jumping from one enterprise to the other. Now left with nothing but the red eyes of vengeance.
Separated is The Authority who has lost control of Rollins' ego.
The new chapter of WWE starts with the most constant person throughout its previous one, Seth Rollins. Doing what his character stated he would do since DAY 1. Buy into HIMSELF.
