#2. Christian turns out to be Seth Rollins' return feud
One of the potential options for Seth Rollins could be a feud against Christian. Christian's return at Royal Rumble was definitely a heartwarming moment, however, Seth Rollins wasn't too pleased by seeing the returning Captain Charisma. Eventually, it was The Messiah who ended up eliminating Christian from the match.

At the 2021 Royal Rumble pay-per-view, Seth Rollins finally made his return to WWE. The Messiah, who was a part of the Blue brand, is expected to rejoin the SmackDown roster once again. But, upon his comeback, it will be interesting to note what plans WWE has in store for the former Universal Champion now that he is back.
A feud against Christian could be a solid option for both Seth Rollins and the former WWE World Champion. That way, Christian could also stay on SmackDown, if Edge eventually decides to choose Roman Reigns as his WrestleMania 37 opponent. Rollins himself has had his fair share of issues with Edge in the past and WWE could use that angle for a potential Christian-Seth Rollins feud.
