#4. Batista retires instead of Triple H
Batista is back after nearly 5 full years away, and he's become a bigger star than ever. He's back because there's always been only one final program that's really interested him, and that was against Triple H.
For the last few years, he was unable to do so because Triple H was busy putting over younger superstars. However, now Batista gets to do it on his own terms, and he's the heel just as he would have liked to be (he's actually very critical of his babyface character, calling himself "the worst babyface ever").
Now, there's a retirement stipulation for Triple H if he loses, but what if Batista ends up calling it a day instead. As we said, there's no other program that interests him and he's not going to be putting over younger talent, because he's too busy in Hollywood. It would be crazy if Batista declared his own retirement after losing.
