1. Sam (though really SamnDean)
4. Ties: Zach, Lucifer, Alistair and Uriel (curious how my fave "evils" and angels. Something screwy there me thinks. Cool tho).
6. What is and What Should Never Be (still!). Though Mystery Spot and the Xmas one is RIGHT UP THERE! (damn you Carver!). Oh and In My Time of Dying (actually I think THAT one might be my all time fave).
7. Cas/Hannah (they are too a thing). Sam/Cara (Sex and Violence). Though really there's only Sam/Dean.
8. LUCIFER! (did Michael ever really feature?)
10. Kim Rhodes
11. So many. Too many. Off the top of my head: Dean: "Well, we know a little about a lot of things. Just enough to make us dangerous".
