Soldier (Greeks Bearing Gifts)
From Tardis Wiki, the free Doctor Who reference
This soldier served in the British Army. He was with a prostitute in a forest in Cardiff in 1812. When she said something the soldier found offensive (suggesting that it was his "first time"), he slapped her twice. In response, Mary scratched his face and ran further into the forest. Mary was possessed by an Arcateenian when the soldier caught up. He shot her but, as she was possessed, she survived and proceeded to kill him. Almost 200 years later, his remains were found and analysed by Torchwood Three. (TW: Greeks Bearing Gifts)
