I feel like at least one of the members of the group should go at least a bit evil at first.
It should either be Dean or Parker, I think. Because (version one) Dean's already been exposed and is more likely to down that road again. Or, (version two) Dean is immunish because he's already been exposed.
Cas is probably the least likely to go dark because he's an angel, though it would affect him eventually?
Oh, and a time skip sounds cool.
