I don't know if it's so much that Sam was cool with killing Nancy so much as not being able to think of another plan. Trading one life for over thirty isn't the worst idea ever. Sam may be very smart, but he's also a fairly linear thinker. Dean's the creative one and was able to come up with an alternate plan that Sam hadn't thought of. I kind of like to compare it to my relationship with my former boss. She's very creative, but not at all practical. I'm totally the opposite. The upshot was that she would come up with all these plans for our workplace, and I would figure out how to make them work.

I think the only reason the demons let Ruby go was basic psychology. She had a knife that could kill them (and apparently had killed a few on her way in), and although Ruby was no match for thirty demons, none of those demons wanted to be the first to attack her because the first five or six of them were almost guaranteed to die before the rest of them overwhelmed her. Since no one wanted to go first, no one did, and she just walked away.

I loved Dean's bonding scene with Henriksen. I really would've liked to have seen him become a hunter. Maybe in your fanwank, Henriksen can team up with Ash. Ash can do the research, and Henriksen can do the field work.

See you in April!
