Ada Gillyflower

Ada Gillyflower was a Human living in Victorian Yorkshire. She was blind and had scars on her face. Ada attended her mother's sermons and was used as an example of human ignorance. Her mother claimed that she was attacked in a drunken rage by her father, resulting in her blindness and scars.

Ada was told to dump the Doctor in the river after Mr Sweet's process was complete, but the process went wrong and the Doctor survived. She locked him away and referred to him affectionately as 'her monster'.

When the Doctor was restored, he told Ada the truth about her mothers actions towards her, and she turned against her mother, even beating her mother with her stick after her mother admitted the truth about her experiments. Her mother used Ada to create an antidote for herself. After Clara destroyed the rocket launcher, Ada's mother held a gun to Ada's head to hold the doctor back. When her mother was killed by Strax, the Doctor asked her what she would do with her life, in which she replied; "There are many opportunities for a bright young lady".
