Whatever teacher they have cannot possibly have as much of the right kind of information as this man here, so Rose just ditches her seat entirely and moves to sit on top of the empty desk next to him. "Tell me about the nine dimensions? If you can? I think I know the first five maybe? Point, line, depth, time, and choice??? Okay, not so sure on that. I was rubbish in maths and science. Thing is though," she hopped off the desk into a chair, leaning backwards on it so she could rest her elbows on the desk and peer up at him, not even consciously trying to be cute, but definitely a little disarming out of habit like when she wanted something from her father or the Doctor.

"I've been traveling dimensions lately, just before coming here. I know I've been 2-D, and without sound and stuff, but I've been doing it all very blind. Just human, me. Determined human, but still--" a vague gesture to everything around them. "Fumbling in the dark."
