I currently have a poll up on my profile to decide which of my current five story idea's for the series I work on first. Note that I will not post one until I finish a few more WIP's (Works in Progress for those of you who don't know). Listed are the crossover and the pairing.
And I will not change the pairing, as these are stories I already have, somewhat, planned out.
Star Trek: Voyager-B'Elanna
Law and Order: SVU-Olivia
