Ah, I suspect it's the eye of the beholder for a lot of it - I focused primarily on the driving forces behind Nick, the burning loyalty, trust and strength, and once the actual slash concept's been overcome then I found there to be only one little nudge over the hill before it strangely became natural. Mind you, there's a lot of hints in the canon that could be used, but then again I always look out for those more than most other people! - especially when there's a canon fetish club in there *still dancing with joy for that bit! Oh, the writers deserve chocolates* Weirdly enough, I found the hardest part for some people was actually the concept of Gil/Nick instead of either Warrick/Nick or Greg, but thankfully they get over that pretty quick too ^^

Ah well, as long as it all makes vague sense and consistency, we can have a bit of artistic license over it ;)
