Lorna Bucket

Lorna Bucket was an inhabitant of the Gamma Forests, a 'Gamma Girl' who became a Cleric of the Church after her encounter with the Eleventh Doctor as a child. She was killed during the Battle of Demons Run.

Biography
Lorna was born and raised in the Gamma Forest and first met the Doctor when she was a young girl. They were involved in an incident in which he repeatedly told her to 'run'. She later enlisted in the Church, although the forests were neutral to their cause; unlike other soldiers, she tried to be nice to Amy Pond while she was held captive.

Lorna gave Amy a prayer leaf she had sewn for Amy's daughter. This was embroidered with the closest translation of Melody Pond in her native tongue, "Song River".

Lorna was present when the Doctor confronted Colonel Manton, the Headless monks, and her squad. She later saw the hooded Doctor using his sonic screwdriver to escape. She did not reveal his presence, but gave chase.

She stayed behind after the Doctor's army arrived and drove the other Clerics away. She overheard Madame Kovarian talking about a trap and tried to warn the Doctor's allies. However, as she was a member of the Church, they were sceptical until she explained why she had enlisted: it was the only way to meet the Doctor, a mighty warrior, again. When Amy said that the Doctor was not a warrior, Lorna was confused because the word "Doctor" translated as "mighty warrior" in her native language. Unfortunately, the warning proved too late, as the Headless monks had already killed most of the Silurians.

Lorna was fatally wounded in the melee against the monks. The Doctor consoled her in her last moments, thanking her for helping to save his friends and assuring her he remembered her, that he always remembered those he met. After she died he asked who she was, suggesting either he had yet to meet her in his timeline, or that he did not remember her. He agreed with Madame Vastra that she was extremely brave.

River Song used the prayer leaf Lorna had crafted to show Amy and Rory Williams that she was their daughter, Melody Pond. (DW: A Good Man Goes to War)
