Hm, have you noticed how the producer made sure the audience saw the fairly sexual scene between Sam and Ruby? and then in the latest, Dean and Alice i think her name was. (the angel)
I can't remember in the previous seasons or episodes where it was that much shown... maybe there was but I can't remember. anyway..
Sam & Demon + Dean & Angel. Possible pregnancies? because they wanted to show us that ruby wants to keep that body even after being tortured maybe so that later on she can be pregnant by sam.. just a possibility... and alice may get pregnant too from dean. tell me what you think?
