no but the more i think about it, the less river-is-ruby's-mom theory seems insane
in the last ep we've got two plots:
Plot 1: Susan Technnologies - is this Susan the Doctor's granddaugther? Oh BY THE WAY the Doctor doesn't know who Susan's parents are!! Kate specifically (for no reason really) mentions a DAUGHTER. The Doctor has at least one child he has never met!
Plot 2: WHO is Ruby's mom??
Who's the Doctor's daughter? Who are Ruby's parents? How can these two questions be in the same episode and not be connected?
If we assume that the Doctor already has had that kid, and it is not in the future as he seems to think, there are not many candidates for who the mom is
Especially when you add the Song-in-her-soul thing, RS initials, River canonically wants a child with the Doctor, mentions of diaries and music without the need for humans, "spoilers", Ruby's mom in that cloak, pointing at the Sutekh, meaning she knows something. Ruby's mom is clearly not a normal human woman; photographs of both Susan and River on the Doctor's desk. STEVEN MOFFAT IS WRITING THE NEXT CHRISTMAS EP
But what really makes me tick is the last episode and those two questions.
*sobs in denial*
