After returning from injury on this year, Ambrose was all set to take things to a new level, but the WWE wasn't looking for the same, and instead, they used him to get the fans over with Reigns.
Later, they made us believe that Ambrose is going to turn heel against his Shield brothers in a week or so, but this week after knowing Reigns' condition, no one would have ever thought of Ambrose turning heel.
A match was already booked for the main event for this week where Dean Ambrose and Seth Rollins were set to face Dolph Ziggler and Drew McIntyre for the Raw Tag Team titles. The Shield ended up becoming the new Raw Tag Team Champions but then, all of a sudden, Ambrose turned against Rollins.
The Raw roster was already feeling the absence of heel superstars, but now things may change for good. Ambrose’s heel turn could become the change he needed to convert himself into the main event superstar like his former teammate Seth Rollins.
Now Reigns is no longer a champion, and therefore it wouldn't be shocking if Ambrose, somehow, finds a way to get the title on his shoulders.
