Mostly, this was an excuse to have Dean singing in a fic. :D

Well, okay, that's really a lie, but it's a good one.

And I think you are the first person to say anything about Jo whispering in Latin! That was one of my favorite parts of the fic, and then I had to mirror it with Dean singing of course.

As for my hometown: It's exactly where I could see them settling down after everything is said and done. Unless they settle in Idaho, that is (which was also a gratuitous plug for my stomping grounds - that's where my mom's family is from).
