Ok, this is pretty bare basic plots (With a the funny episode that are my favorite thrown in) I think it's ttly worth watching all, but this is what you NEED to be caught up.
This is season one, lemme know when you finish that, and I'll do season 2:
Pilot Home Scarecrow Faith Nightmare Shadow Something Wicked Dead Man's Blood Salvation Devil's trap
I would also highly recommend (these are not in order, the above are): Skin The Benders Hell House
And anything you miss, or are left asking about, lemme know. If you follow those, you'll miss some of their bonding, and it'll seem like Sam gets over Jess really fast)
