The WWE tends to like storylines to pay off, even if it takes a year or more. Remember the Undertaker and Brock Lesnar's confrontation in the stands after Lesnar's fight with Cain Velasquez? The company has set something up by having Rousey toss Triple H out of the ring at Wrestlemania 31, and going after Stephanie's arm. Just like they set up her Wrestlemania appearance when she turned up at SummerSlam in 2014. They'll ensure this set up isn't wasted.
