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 where 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. She did so in order to meet the Doctor, considered by her people to be "Mighty Warrior", as his name is defined in their language and also because she felt the forests was only exciting when he was there.
She sewed and gifted Amy Pond with a prayer leaf for her daughter which was embroidered with the closest translation of Melody Pond in her native tongue, River Song. She also revealed to Amy that she had met the Doctor once as a child.
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 position.
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 a member of the Church they were skeptical of her motives until she explained the only reason she enlisted was to meet the Doctor. That it was the only way to meet a great warrior. When Amy states that he is not a warrior, Lorna is confused because his name is "Doctor", which translates into "Mighty Warrior" where she is from. Unfortunately the warning proved too late as the Headless monks had already sneaked aboard and 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 remembers those that he meets. Later it is revealed that he does not know who she is, that he pretended to remembered her, implying the events she recalled had not occured for him yet. He notes 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)
