Christine Hoez

Christine Hoez is a young lady who is very important in regard to Daniel's past. The author states that Christine is based on (and "played by") Christine Auten, the voice actress for Sakaki in the English dub of Azumanga Daioh.

History
Christine was a girl that Daniel Benfield fell in love with during their travels together but, upon becoming the Doctor, her personality began to harden to the point where Daniel was occasionally forgotten about (or, on several occasions, nearly locked out of the TARDIS). While Daniel continued to love her, he was far too afraid to say it out loud since she had grown cold and distant.

After three years with Daniel (one as the Doctor), Christine was killed (Stronghold of the Daleks) by a Dalek firing squad. Witnessing these events caused Daniel such grief, sadness, and anger that he destroyed the Daleks and quickly left the planet.

The depression that set in caused Daniel's mind to block out the truth, leaving enough brief shards to convince him that he was her and had been killed while destroying the Daleks; how he regenerated and got back to his Ship, he figured, was not worth the time to investigate.

It was revealed during Azumanga Who that Christine loved Daniel in the same way, but never told him how she felt and regretted it.
