However, Russo added that the controversial finish to their match only meant that the feud was far from over."I do love the fact about the promo where he said, you know, he went away and he came back and nothing had changed. There was a little truth to that, and you know, that he basically came back, and it's the same stuff. He's in the same spot, but you know those are the things you got to really pick up on, man, because that's where the frustrations are coming through. An awkward finish with the ref spot, but this just tells me they're going to just continue on with this Priest and Black angle," Russo said.It will be interesting to see what plans WWE has in store for Damian Priest and Aleister Black's rivalry moving forward.
