Not ma-hoo-sively into a lot of this, being a dash convoluted, but there are plenty of golden nuggets within. For a DWA strip of all things, it's a prototypical example of the kind of "parallel evolution" that Moffat described for the Cybermen; vampires emerge in different forms and guises across the universe, be they virus, species or curse. Some fun tidbits too: did you know that Time Lords have a vampirism vaccine?
