4 Reasons why Dean Ambrose confronted Triple H on Monday Night Raw
#2 To remind everyone that he has not forgotten what Triple H planned that night in 2014
Another significant reason why Dean Ambrose expressed his anger towards Triple H and Seth Rollins could be related to where it all started in 2014 when Seth Rollins joined hands with Triple H, took a chair, and stabbed his own brothers in the back.
Considering it was Triple H's master plan to get rid of the Shield, coercing the Architect to look at the bigger picture made the latter choose his own path than to stay committed and loyal to his brothers.
Despite the fact that the Lunatic Fringe is currently working as a heel, it could be one of the biggest reasons, if not the biggest to why he has always held a grudge against someone like the Cerebral Assassin.
The anger in Dean's words was pretty evident and made the fans believe that the former WWE Champion has still not forgotten the night when Seth Rollins sold his soul to The Game and left his brothers unconscious in the middle of the ring.
