Someone Else Entirely.

Susan, the Doctor's granddaughter. Yep, her. In 'An Unearthly Child', her grandad loses a diary which details his life on the TARDIS, and we never knew what became of her. Real Time Lady, is she?

The Doctor's wife. Um. Well. You know. Would explain the 'sweetie', and all the flirting. And her 'it shouldn't kill me that he looks right through me, but it does' comment in TLoS.

The Doctor's Daughter. You know, rumour has it that Moffat requested for her not to be killed, so... phhh?

The Doctor's mum--nah, let's not go there.

The Doctor him-- er. Herself.

The Rani.
