#3 Returns to betray The Shield
Maybe Dean Ambrose comes back next week and says that he's got his head right again. He wants to be rejoined with the brotherhood known as The Shield, and he's sorry that he ever turned his back on them. And then, when they turn their backs, Dean Ambrose does to The Shield what Seth Rollins did to them. It would be a very interesting plot twist.
Rollins could take exception to this and challenge Ambrose to a big match. The Intercontinental Championship, that's been all but forgotten, could be revived again.
