#4 Ambrose joins The Shield, turns on his brothers
It does seem like Dean Ambrose has turned over a new leaf, does it not? He urged Seth Rollins to slay the beast not long ago and even went on to tease a babyface turn when he asked Rollins why he didn't come to his aid when he was in peril. So last week, after Reigns' return, a Shield reunion was teased again.
Let's just assume for a minute that Ambrose agrees to join The Shield and the trio even has a match on RAW where they go on to defeat their opponents. But then, shortly after the match, he lays Roman Reigns out. This could be the premise for an Ambrose vs. Reigns match at WrestleMania.
Ambrose and Reigns have, of course, faced one another in the past. But there's never been a full-fledged war between the two men on a stage like WrestleMania.
