#2 She costs Seth Rollins the Intercontinental title rematch
Dean Ambrose picked up a clean win against Seth Rollins at WWE TLC to win the Intercontinental Championship. It is almost certain that the two men will clash again in the contractual rematch. And when the two do collide, chances are that Rollins will be booked to look much stronger.
And then, when he seemingly has the match won, Renee Young could stand up at the commentary table and cause a distraction. This would allow Dean Ambrose to pick up the win. It would allow Ambrose to retain the Championship while Rollins moves on to other things, in weeks that follow.
This may not necessarily be a one-off thing either. Renee Young could constantly cause distractions from the commentary table, helping her husband win his Intercontinental Championship matches.
