Supernatural: Dean/Sam.
This has to be the best take on body switching in the fandom. It’s funny and introspective, and joyfulgirl just has so many fantastic lines that if I quoted them I’d end up having to quote everything, but it’s for moments like these that I love reading fanfic:
because all Dean ever wanted was for them to be together. Not this necessarily. The ‘how’ never really mattered to him. Just that Sam was there.
