Okay, so
this made my day.
First, it spans s1-s6. Second, it brought up perspectives on the Sam/Dean relationship that I had thought of, but never really took the time to appreciate (possibly because I was way too frustrated and disappointed), and then in others it was just YES, THIS. EVERYYYYYYYYYYYYYYYYTHING.
Just. It made me feel so much better about some of the things that made me sadface forever about these later seasons (plus I will never get tired of hearing about the boys' epic love for each other. OTP FTW! >>>>>>>>>>>>:D ).
GO FORTH AND READ. (if, you know, you haven't already).
