Rose couldn't help but giggle, "I could ask you the same question" she began to come out of her stupor thanks to the mouse. "All I know is one minute we are catching a Slitheen, then there was a door... and it led me here. I have been trying to figure out what this place is. Have you found out anything?" A light bulb turned on in her head, "Where is the TARDIS? I'm sure that it has some very curious readings."
In all of her emotion she had forgotten about Fred altogether, maybe she could start traveling with the Doctor again! After they figure out why this place was so...odd.
