Amazing episode.
Hey, you wanna drive?(c)Another monster of the week, and i didn't care that it was Paris. She was just a background, it was all about Dean and Sam, about coming back to DeanSam, about making relationship work.
When a couple tries to get back together and be better, they need to forgive each other, stop blaming one another, get over it, realize the wrongs they did on both sides, and find a new, better way to be better, to be stronger as a couple.
And it's what they are. A couple, with their ups and downs.
But, in the end, if there's still love between you two, you can make it work.
