Lorna Bucket
Lorna Bucket was from Gamma Forest and had met the Doctor when she was a young girl. They were involved in an incident in which he had repeatedly told her to 'run', implying the situation was dangerous. She later enlisted in the Church, despite the fact that the forests were neutral to their cause.
When revealing to Amy Pond that she had met the Doctor as a child, she also gifted her with a prayer leaf she had sewn for her daughter. This was embroidered with the closest translation of Melody Pond in her native tongue, River Song.
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, but did not reveal his presence.
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 about what she had oveheard. However, as she was a member of the Church, they were skeptical of her motives until she explained the reason she had enlisted as it was the only way to meet the great warrior once more. When Amy said that he was not a warrior, Lorna is confused because his name is "Doctor", which translates into "Mighty Warrior" in her language. Unfortunately the warning proved too late as the Headless monks, undetectable by sensors, had already killed most of the Silurian Army.
Lorna was gravely wounded in the battle against the monks. The Doctor consoled her in her last moments, thanking her for helping to save his friends and assuring her that he remembered her, that he always remembered those that he met. Later it was revealed that he does not know who she was, that he pretended to remembered her, implying the events she recalled had not occured for him yet. He noted that she was extremely brave.
Later, River uses the prayer leaf Lorna crafted to show Amy and Rory that she is their daughter, Melody Pond. (DW: A Good Man Goes to War)
