I already once talked about this idea, it's a feud between to wrestlers, one of each show
IMO it should be taken by persons that already gave their face on the first season.
One of the wrestler comes on his show and start talking about how he feels about what happen in the first season. the other one comes out and put is side version of the facts... this could then lead to a confrontation, but nothing much.
on the next shows the two wrestlers have several confrontations for example:
- One of the wrestlers, is having a match, and the other one comes out from the crowd and interfere in the match (funny thing, is if he attacks the rival opponent, because this way the rival looses the match by DQ

)
- Backstage attacks
- etc...
if the two wrestlers are "big guys" the feud can end with a special match, something like a cage fight for example.
IMO Nightwing could be one of the wrestlers... he is a participates in the forum a lot, and is "living" the rivalry... or "the moon" for example
