The Doctor and Ruby in “The Devil's Chord”

In the past, right now, I live in a place called Totter's Lane. 1963, I parked the TARDIS in a junkyard, and I lived there with my granddaughter, Susan.

Oh...!

Okay?

Your what?

My granddaughter.

Susan?

We could go and have a look, but y'know... timelines, [mimics explosion]

Well, y-- you've got children?

I did have -- I will have. Time Lords get a bit complicated.

Yeah, but you've got a granddaughter! Like, now? Like, today? Back in our time? My time. Gah! Where is she?!

I don't know.

How do you not know?

Time Lords were murdered. Genocide rolled across time and space like a great big cellular explosion; maybe it killed her, too.

Doctor! God...
