She's a Time Lady, you can see her in the preview of Ten spinning around and shooting someone with Wilf's gun. He's behind him next to the President of the Time Lords in Time Lord Robes. It's possible she's Romana or the Rani...

Interesting. I hadn't noticed her in the preview, but my theory before that had been that she might be the White Guardian, finally returning. She appears and disappears (and communicates) mysteriously, wear's a white suit (and had a white background on TV), and is apparently trying to stay somewhat distanced from things (avoiding the Doctor knowing she's there). I'd also heard a theory that the White and Black Guardians were gone since the Time War, because they were no longer needed since the destruction of the Time Lord and Dalek races... if that theory has any credence than now that the Time Lords are back, it would make sense for the Guardians to return as well. Of course this could also just be my mind jumping to conclusions since I saw Enlightenment only a couple weeks ago... who knows. ;-) --173.33.173.112 17:46, January 1, 2010 (UTC)

Identity

Was it stated, or was it just left at someone who left him a long, long time ago? IE Romana or Susan? --Golden Monkey 20:00, January 1, 2010 (UTC)

The Mystery

Well, here's my point of view. The way the Doctor looked at her during Part Two I think proves that it was someone he knew well, such as a companion, so I'm gonna rule out the idea of her being the White Guardian. I think she is wearing white because she has died, as if she's in Heaven. You only ever NOT see her wearing White when she travels through time with the Time-Lords, I'm thinking possibly that was because she was alive at that time the Time War was on. I havn't seen the earlier series so I don't know the names of most of the companions, though I'm sure it's one of them such as "Romana". 91.105.246.252 21:01, January 1, 2010 (UTC)

A relation

Is it possible that it is his Grandaughter, Susan Foreman? From the very first episode? an unearthly child, or some other relation to him even though there is the question of the looms how he could conceive children...Or Leila who was left on gallifrey and had a child their. - Greateagle5 21:10, January 1, 2010 (UTC)

I agree with the idea of it being his grandaughter Susan. 91.105.246.252 21:13, January 1, 2010 (UTC)

I do not think it is his granddaughter Susan imagine claire bloom calling DT or MS grandad who are both younger than her. You may argues that time lords are like that and that may be a good twist to have. I do not think she is or the child of leila she survived the time war and did not mention having children. I think it is the doctors mother. --Catkind121 21:18, January 1, 2010 (UTC)

Notice who he stared at: Wilf's granddaughter. We'll probably never know for sure, but at least that's a hint. --Golden Monkey 21:19, January 1, 2010 (UTC)

Claire Bloom was said to be playing the Doctor's mother lots of times, by even her manager. So I think that's about it. When he looks at her, he is clearly in shock, his saddened theme plays, and she briefly looks a him. She knew a lot about the Doctor. I think that pretty much says it. His mother. He looked very sad when he saw her go, ready to cry. Delton Menace 21:24, January 1, 2010 (UTC)

Taking a different perspective to GoldenMonkey, but the same action. When asked by Wilf who the woman was he looks at Donna. This could be suggesting grandaughter...but bear in mind Donna is in a wedding dress. The Doctor mentioned in 'The Doctor's Daughter' that he had a family (including the phrase I think "I had a family once...[BEAT]...and a wife.") and this could be a RTD clue to up coming events (a la 'Badwolf' or doing the series 4 thing and dropping references in every episode) suggesting perhaps that his wife may appear at some point. The woman was in white, like a wedding dress, the clothes wore by DOnna when the doctor looked at her. Well, that's my theory anyway. Pacman100 02:08, January 2, 2010 (UTC)

I heard that Russel T. Daviess said a clue as to who she is is the costume she had when she meets Wilf: completely white. Then weh asked who she is, the Doctor's looks at Donna [Wilf's granddaughter], who is dress in completely white. Hmm. Delton Menace 02:18, January 2, 2010 (UTC)
