There’s only so many times you can put those 2 guys in the ring and just talk.
They put the same people in the ring to talk all the time lol. They've only done it once with Roman and Cody both as faces.
I don't think they have any plans for Roman and Cody to go at each other in the near future and are basically trying to skate through this without damaging either's following as a face. (Probably Cody)
The question would be, why even put Roman/Cody together if you're worried about fans turning on one. My guess would be the overall direction is that Cody is being teamed with Roman to stir up shit with KO, Randy, and maybe even Seth.
What's funny is they really have a ton of directions they could go for Wrestlemania. Cody vs. Rock. Cody vs. Roman. Cody vs. Randy. Cody vs. Seth. Roman vs. Rock. Roman vs. Seth. Roman vs. Jacob. Roman vs. Solo.
There's eight different potential main event matches all with significant story behind them.
