Death really *is* a cool character--I really like his perspective on things. (Though I actually like Tessa, too--I just think she was kind of wasted in this episode).

I suspect that we will see more about the domino effect of Dean and Sam's multiple resurrections in future eps. In a way, it explains the Winchester curse--didn't Tessa say if that little girl lived bad luck would follow her around her whole life? So really this all goes back to the deal Mary made with Azazel.
