Oh wow, this was really nice. A post apocalyptic happy ending, haha. Sam and Dean could not foresee it.
When Sam first starting talking I thought it was just Dean imagining it because it came out of nowhere but then he just kept on going. I was disappointed to see that he didn't personally regain his memories but the base of him was still Sam. I wasn't surprised that Sam and Dean eventually got caught, but the way it happened made me laugh. I didn't want this to end!
