#3. Dean Ambrose turns on Roman Reigns, WrestleMania match is made
The Shield takes on Bobby Lashley, Drew McIntyre, and Bobby Lashley at WWE Fastlane in a showcase match. This is their big reunion and perhaps the final time that the Hounds of Justice hunt as a pack, side by side.
But one major twist that could potentially take place during the pay-per-view could see Dean Ambrose turning on Roman Reigns to set up a WrestleMania 35 match. Bear in mind that Roman Reigns, who's main evented the last four WrestleManias, does not have a match for the show yet.
Dean Ambrose's future is also up in the air, and if this is indeed his last run, he may want to work with one of his best friends. Reigns and Ambrose would be quite a heated rivalry.
Plus, Dean Ambrose honestly never really got to showcase himself as a heel.
