3 reasons why there could be a Shield reunion very soon 

#2 WWE might have teased it this week on Raw

WWE has started portraying Dean Ambrose as the same old Lunatic Fringe

After asking Seth Rollins to 'slay the Beast', Dean Ambrose turned babyface two weeks ago on Raw.

However, WWE has started portraying him again as the same old "Lunatic Fringe" who was a vital part of the Shield. As a matter of fact, after losing a match to Drew McIntyre, this week on Raw, Ambrose asked Rollins why he did not show up, teasing a potential alignment in due process.

Thus, it seems the creative is pushing Ambrose as the Lunatic who does not give a damn and goes on doing things in his own unique and badass manner. And arguably, by teasing a potential alignment of the two former members of The Shield, WWE might have taken the first step towards a potential Shield reunion.

Given WWE teased a potential reunion of Rollins and Ambrose, and with Roman Reigns expected to return very soon, there is a high possibility that we could be in for a potential reunion of The Shield.
