Oh, R/S is so canon. ;-) If JKR wanted to convince me otherwise, then she shouldn't have had the last appearance of both characters be them all together and young and happy and did I mention together? Yep, that's my story and I'm stickin' to it!

And, um, anyway. Thank you so, so much for reading, and it is certainly beyond okay if this pops up on a rec list in the future! :)
