They have three more weeks. This Smackdown proves that Cody and Roman don't have to see each other every single weekly episodes because they will deliever but as you said it should not be purely based on custody of Dusty Rhodes
Cody should remain at this "It's very personal now" but talk less about Dusty and more about himself. I trust Hunter with this one. Hope they will kill it with the upcoming promos.
I still vouch for Cody being a tweener, sooner or later the underdog babyface fuel will run its course.
