#1 - Confrontation With Elias
During a recent edition of the Steve Austin Show, "Stone Cold" named Elias as one of the guys he'd like to face if he ever comes out of retirement, which could mean that he's going to show up and confront Elias during his live performance this coming Sunday night.
As mentioned in the intro, WWE is trying to figure out a role for Steve Austin at WrestleMania 35, and him coming out and hitting Elias with a "Stone Cold Stunner" would definitely be a memorable moment. Sure, it might not do much for Elias, but it's possible that WWE could be thinking that him simply just being in the ring with a legend like Austin will be enough to take him to the next level.
Of all the possible scenarios, this would give Steve Austin a chance to make the biggest impact possible, and on top of that, it could set up a future match if he ever changes his mind about coming out of retirement.
