The first story you're talking about is In Your Absinthe, by diamondback158 it's a wip, she's not updated in a while, but I know for a fact that she intends to finish, she has just gotten busy with professional writing gigs.

That's a link to all the chapters she has up so far in her journal. I'll give her a nudge and let her know it's being asked about again. I want another chapter of it too. *wink*
