No idea where it came from but here's how I see it going down that would kind of make sense for Austin to show up.
Bloodline is going to kick the absolute shit out of Cody for a while. First one down to break things up is going to be Jey, who will end up chasing off Jimmy. Second one down, it's going to be Cena coming back to get his revenge on Solo and chase him off. All that's going to be left is the Rock and Roman, beating the shit out of Cody. Queue the Glass Shatters and here comes one of the Rocks all time enemies, Stone Cold. He comes down, they go back and forth for a little bit, Stone Cold hits the Rock with a stunner, the Rock sells it harder than he ever has, even in the old days, and that takes the Bloodline out of the picture leaving the fight as just Cody and just Roman.
The only thing I'm unsure of is if they're going to push Roman for another 6 months of absenteeism so he can pass Hulk's streak or if they'll do the right thing and give Cody his flowers while he's BURNING hot. Frankly, if they don't, they might as well just fire Cody because they will have officially killed all his momentum.
