WWE Fastlane 2019: 4 unbelievable swerves that could shock the WWE Universe at Fastlane

#3. Dean Ambrose turns on Seth Rollins and Roman Reigns

The Shield are back together for the fourth time after Roman Reigns' major announcement that his leukaemia is in remission. Everything is right with the world! But, what if Ambrose was just lying in wait for the perfect time to once again turn on his Shield brothers?

The perfect time, of course, being the Six-Man Tag-Team Match at Fastlane between Seth Rollins, Dean Ambrose and Roman Reigns and the randomly formed heel group of Baron Corbin, Bobby Lashley and Drew McIntyre. WWE is teasing the reunion of the trio as "one last time" before Ambrose makes his exit from WWE. Only time will tell if Dean decides to finally stay or leave the company, but there's no doubt that the three superstars are sure to cross paths in future.

This major, yet perhaps not too unexpected, swerve would justify WWE's decision to add the match to the card in the first place, and build towards an intriguing match at WrestleMania.
