Do Sam and Dean's sweet brotherly moments ever not centre around horrible things happening? STUPID BOYS, WITH THEIR STUPID INABILITY TO EXPRESS HEARTFELT BROTHERLY LOVE WHEN THEIR LIVES AREN'T CRASHING DOWN AROUND THEM. Also, I find the concept of Sam having sex with a girl and her not subsequently dying horribly a difficult one to comprehend. In fact, by now I imagine Sam would probably be too freaked out by the possibility to have sex with anyone.

If you actually did write Sam/Riona, I would be so amused. (You can call me Riona Leonhart if you like! I feel like a Riona Leonhart in real life sometimes, after all.)
