#7 Seth Rollins and NOT Dean Ambrose turns on The Shield

A lot of fuss is being made over a Dean Ambrose heel turn ever since he returned from injury earlier this year and the WWE is certainly having a lot of fun teasing dissension within the Shield and a possible turn for 'The Lunatic Fringe'.
The most recent episode of Raw had Ambrose triumphantly help Seth Rollins qualify for the World Cup, only to end up almost coming to blows with him after losing his opportunity to do the same. Roman Reigns being the peacemaker is the only reason it didn't happen.
Look who just shut down all of Tony Khan's critics! More HERE.
But what if Ambrose isn't the one to turn? It'd be too obvious now, right? They've baited it and not delivered too many times. What if someone else within the Shield is the one to turn their back, and it won't be Reigns, so what if it's Rollins... again?
