Wow, dude. This was really REALLY really amazing. There were so many single lines that just completely describe Sam and Dean. Like Sam thinking about Dean needing him more than he needs Dean. Like the whole thing with the thing packing a wallop. And Dean insisting that they're good at figuring out puzzles ...

I REALLY enjoyed it.

And also may love Sam (and you) a little for this line: "Nice to know there are orifices you won't go for"
