#2 Shield reunion #3?

Things are getting interesting with Roman Reigns' return. Firstly, Dean Ambrose has been in a weird place (as if he isn't crazy enough already), where he's seemingly forgotten what happened in the last few months.
He even approached Seth Rollins asking "where he was" during his match with McIntyre two weeks ago. After losing a No DQ rematch to McIntyre (thanks to interference from Elias), he found himself being beaten down 4-to-1.
Roman Reigns and Seth Rollins came out, making the save. It was also the first time we saw Reigns in action since October. However, a Shield reunion was never officially confirmed. Reigns and Rollins didn't really help Ambrose, but they just looked at him and walked away.
Reigns naturally would not approve of what Ambrose did to Rollins and had to say about The Shield. But with enemies on the horizon, will the dynamic trio reunite one last time before The Lunatic Fringe calls it quits in WWE?
