This was so sweet. Stories like these make me appreciate 12 a lot more :)
Despite the title, I started out thinking this was granddaughter Susan, but things didn't fit, and then I realized it must be his mother. Nicely done, and really nice characterization of Twelve.
Oh, that was beautiful. Very, very nicely done. :) I never saw it coming.
This is brilliant! I've never really put too much stock in the "half human on my mother's side" canon, but you have weaved a believable story out of it. Love it!
I've never been into the "half human on my mother's side" thing, but damn, you made it work.
Oh, wow... I loved this! Nice work on the twist. Very clever, and very well done. Just enough info to let the imagination take over the rest. Bravo!
