Ficlets blossoming into epics - yes, I do have some experience with that. (The Willow/Don story was suppose to be ~3 parts.)

As for Ezra - never fear, he is well cared for in my hot little hands. If I can get my butt in gear and finish the half-written fics sitting open in word, you'll have 3-4 Ez fics for 14valentines. :D
