Well, the best spot for a cliffhanger is the most cruel spot too, so the two aren't mutually exclusive, anon. :D And in your story's case, definitely not mutually exclusive. HEHHEHEHEHE

Also, this reminds me of poor Danny Wallace's comments about "Italian Homoerotic Essays" when he found out about all the Desmond/Shaun slash fanfiction. XD

And I certainly hope you'll find the time and inspiration to write that backstory, although the current story is extremely satisfying in on its own. :D
