They're going to be feuding off and on for the next decade. No need to blow the wad on the emotion now.
I have a feeling they will be kept separate for a good amount of time. They could've gone to next level here and revisited later no problem. They were starting to amp it there and then it became about Jericho.
If I had to guess Zayn will feud w/Jericho at SummerSlam.
