In my opinion at this point what should happen is Ambrose could return and accidently cost Jordan & Rollins their newly won tag title. One of the main reasons I think that this would be a better idea as it would keep Jordan in a big feud and continue to allow him to work with top stars. Ambrose could even work with Jordan ahead of working with Rollins given the idea that Dean's problem technically isn't with Seth, but more with the one who took his spot.
Now we move onto the other member of The Shield which is Roman Reigns the current Intercontinental Champion. Looking at the current landscape of the championship is occupied by Samoa Joe and not based on anything dirt sheet based it is clear to me that Joe will become champion at some point with Roman moving into a new direction. This likely means that Roman will be open for a rumored match at WrestleMania against a certain World Champion.
