While Ianto,Gwen,Jack and Owen were walking Ianto saw a familiar face.
"Lisa!"he called out and ran over to her.
"Ianto could still be a cyberman!" Gwen called after him but Ianto didn't seem to have heard her. He picked up the container of oil and oiled Lisa who was indeed did look like some weird crossover between how she looked when she was a cyberman and the tim man. Then she ran after them with an axe.
"You just had to oil the tin woman didn't you Ianto?" Owen asked as they ran.
"Quick though the river!" Jack exclaimed remembering just in time how the snow had rusted the tin man in the movie. So they ran though the river and the tin woman followed them and rusted.
The stood on the other side of the river, waiting to gather their breath and not really wanting to pass by the tin woman again even if she was rusted.
"I'm sorry about Lisa," Gwen told Ianto.
"It's not your fault,"Ianto replied but he wondered how many more times he was going to lose Lisa.
