Fic: Mercy 4/4

I think I'm gonna make this into a one-shot longer fic and post it on the bds_fic group.  I'm thinking it should be read in one sitting.  You might need to re-read part 3 before you hit this one. the transition between them is sort of important.  Same death/angst/violence warnings as the other bits.

anyways, hit me with some concrit, please.
