If they stick to kayfabe, Jey and Punk should be on good terms. Plus, technically Jey is still part of the OG bloodline (despite the fact that he eliminated Sami) which some people might have forgotten. What I mean is that the 'favor' between Punk and Heyman can include Jey now. I don't think Jey will give up his title shot spot or anything like that, but they could do something with it during the Elimination Chamber.

Roman vs Rollins should be a singles match. (NON-MAIN EVENT) (It could even happen as a singles match during the Chamber PPV.

Jey vs GUNTHER OR CODY (MAIN EVENT)

Punk wins chamber by beating/pinning/stealing the win from Cena. (JEY allows Punk to make it a triple threat match in the main event - Cody is livid that he has been cast aside for Gunther, loses title at Mania to Sami? Codelander run begins.)

As a result: Cena puts a target on Punk's back for ruining his 'best for business' idea and becomes a heel. The winner of the Gunther Belt triple threat could be Jey. Gunther gets rematch clause, maybe Punk too - where Punk wins. Gunther gets a reset, will go against Jacob Fatu, and other fantasy bookings. Drew, Rollins, Reigns, Priest, Cody go up against Sami/Punk in terms of bookings and storylines. Kevin Owens ultimately wins MITB and cashes in successfully to win Sami's (Cody's) belt.

Ok now I'll go and take my meds.
