FIC! Genetic Transfer, Ten/Martha. Doctor Who. 2/?

A short piece that follows Genetic Transfer; if you haven't read the first part you should, in order for this part to make sense. It's a short one, too. :-)

I'd written the first one as a one-shot, but people who commented got me thinking, and as usually happens when I start thinking, I started writing :-) A big thank you to domsbabygrl for the quickie read-through and general fabulousness. :-)

Genetic Transfer, part two.
