#5 Dean Ambrose just never forgets what happened on June 2, 2014
There's no denying that Shield was propelling to become one of the most feared factions in the entire wrestling industry, and after they annihilated Evolution, Rollins' turned his back on the Hounds of Justice and destroyed them.
The entire WWE Universe went silent as the Architect continued to hit his brothers with multiple chair shots that echoed throughout the arena, with Triple H and Randy Orton looking from the outside.

Since Rollins' sold his soul to the Authority, the Architect went ahead to become more successful than any member of the Shield and did so, at the expense of his brothers.
Considering that Ambrose waited the entire night to turn heel suggests that he never had any problem with Roman Reigns and was always waiting for the right spot to inflict pain upon the Kingslayer who stabbed them in the back.
While Roman Reigns moved ahead and started feuding with Randy Orton in 2014, it was the Lunatic Fringe who was hell-bent in destroying Seth Rollins' after what he did to them.
Judging by how it all transpired this Monday Night, it definitely feels like Ambrose will probably never forget the night his own brother stabbed them in the back to fulfil his own personal motives.
