Samantha frowned at the Doctor's confusion over his name, nodding, "Yes, The Doctor. That's your name." She sounded worried and looked up at his hand. It was more likely at this point it wasn't there from frustration but pain. She nodded again when he seemed confused about their meeting, "Yes, last year. You don't remember?" She exhaled slowly. Well, at least she had something to do today.

"Kidna- whoa, whoa, whoa, you alright?" She asked as he fell, kneeling down beside him. She put her folders on the ground and tried to steady him, "Sit, let me see your head." She gently pulled at his fingers, trying to see where he was holding his head. "You've probably got a concussion, I could..well no actually that won't work." She seemed be talking partly to herself as she considered how to help him. "Do you hurt anywhere else?"

"I'm Samantha," she said as she eyed the screwdriver he looked at with confusion, "and that is your sonic screwdriver." She looked around, pursing her lips. She started mouthing words, deciding getting him somewhere safe would be a good idea, but not a hospital. Should probably also find the alien ship, they could deal with it when the Doctor wasn't extremely lost. "The spaceship, roughly which direction is it?" She asked, making a mental note of where they were so it could be found later.
