Sarah and Tucker have a very complicated relationship. I've been playing with these two for 5+ years now but I've yet to write anything substantial for them. The stuff I have written doesn't always follow a canon because I have no idea how I want the story to end. I've been using challenges to flesh them out and try out different plots and stuff.

I think all the ones I've posted are tagged here. I refer to it as "The Story".
