After 20 minutes of murdering Shane, UT will hit a chokeslam, then be down on his hands and knees catching his breath. Out from under the ring, a returning Rollins does the curb stomp and rolls back under the ring, giving Shane the clean pin. Rollins is Shane's new boy, you get Rollins/HHH for the title at backlash or whatever.
Then they can have UT kidnap Marissa as revenge on Shane or whatever, to get him to give up the shit in the lockbox, and there's your summer story.
Oh, and Nash comes out and powerbombs Roman back to his home planet, to the hugest pop in the world.
