So after reading the extended description of the sixth season of Supernatural on ONTD_spnparty, I noticed lots of talk about Samuel (gramps Campbell), and it got me to thinking about the potential angst.
I'm thinking that if they are doing the whole Sam & Dean swap S1 personalities then Samuel is going to be the new John. In my head this is basically how it's going to go...
Dean: I just don't understand your blind faith in the man Sam!
Sam: He's family!
Dean: I'm your family!
Sam: Go back to Lisa.
I'm going to make a bet with my brother and ask for a $10 bonus if Cas shows up to warn Dean that "Nothing is as it seems."
