#2 To turn Ambrose heel
The rumours regarding the heel turn of Ambrose have emerged in the past few months, but still, the Lunatic hasn't turned heel yet. The fans are expecting his heel turn in every pay-per-view but it seems like it's not going to happen anytime soon. However, there are still chances that in his upcoming match Ambrose might turn heel.
Most of the time, superstars turn heel when they are unsuccessful in winning the championship. Let's assume that somehow because of Rollins, Ambrose doesn't become the Raw Tag Team Champion and because of that frustration, he turns heel by attacking his partner.
This seems very unlikely at the moment but we can't forget that in the WWE, there's always a chance for anything to happen.
