For real. It will be Badd Blood 2.0. Taker will destroy Shane. Toss him off the cage Mick Foley style. The crowd will

. Linda and even Steph will come out with the EMTs to check on Shane, with both women crying. Vince will come out to the stage with a look of concern for his son.
The crowd will be on fleek, chanting Holy shyt! and This is awesome! Taker will come down from the top of the cage, then pull Shane off the stretcher and into the ring. He will do the cutthroat sign and will be about to set up Shane for the tombstone when we hear "Boom, boom, boom boom boom". The crowd comes even more unglued as Berg runs down the ramp and into the ring to spear a bewildered Taker. Then the Jackhammer. He puts Shane's hand on Taker for the 1-2-3.
WM ends as Berg is giving Taker the cutthroat sign from the stage once Taker gets up. They both stare each other down as it fades out.
The next night, Berg says he always respected Shane and disliked Taker. He disliked Taker for being part of the WWE that sonned WCW. He'll acknowledge that Shane was his boss when he owned WCW in 2001, but Berg didn't join the Invasion because he needed a break, but he regrets it and is back to make amends for Shane, and to destroy Taker.
Taker cuts a promo saying he won't forgive Berg for ending his WM career with a 2nd defeat. This leads to a SumSlam match.
