It's not truly a crossover, though, just put it in Lochdubh and borrowed Hamish for a few scenes. :)
Yeah, that lesson was the turning point for both of them, I think, and as for the sex, after writing Snarry for years, I wanted it to be a bit 'different', so I'm glad you liked it.
Awww, you made me blush, go on! I'm so glad you liked it, hon.
