I think I more just figured out Kaga's sex/gender (assuming here that she identifies as her own sex) over time...
Might have just been a guess on my own, maybe Kaga said something a while back that hinted/gave away her sex and I'm forgetting it.

Also, looking back on that video... apparently I was wrong. We made it through season 8 without the Valeyard making an appearance. ...Also I remember reading somewhere that Steven Moffat said he never really understood the concept of the Valeyard. That's probably for the best. @_@

Who/What's Valeyard?
