[@Wolvena] I'm thinking about bringing in some new Gods as well as demons that have different persuasions (like the dancing demon in Buffy lol).  

This season is mostly about Lilith trying to break the seals.  So, if anything, we can have Lilith and her demons set up distractions to try and keep them busy while they break seals (they pretty much did this in canon anyway).  Meanwhile, the brothers are going to have to deal with their fighting issues they seem to have the majority of this season, with the demon blood story.  

So, eventually, its probably going to be a "my side or his" for every single character.
