Well, I didn't really "see it" at first, but then at some point it just... happened. And I've been obsessed ever since!

I saw it pretty early - in the disinterested "Ah, I bet they are the primary slash pairing around here" sort of way, but it took until Season 5 and Grave Danger (that episode! Bloody hell, Quentin, bloody hell!) for me to see my way to writing it (Nick didn't have enough depth as a character for me before that).
