Not a problem; I've only been checking my lj every couple of days since I've been trying to write my thesis. :P Glad my comment made you happy though! :D

I certainly think their relationship oozes a D/s dynamic, but it can be interpreted in a lot of different ways. That's part of the fun though! It's nice to experiment with different approaches to the same pairing in different fics, and Blackwood/Coward can potentially work for almost any type of D/s relationship imaginable- which is quite a lot of options!
