Rose ran closer to the TARDIS, then stopped, searching for the most awkward pose she could make just then. She watched the TARDIS disappear, while the dupilcate came up next to her and held her hand, making her look all the more awkward.
They stood there for a while, then the duplicate said "Well, assuming one of three people selected to travel dimensions was Jackie Tyler, I am assuming there is no actual Torchwood here."
"I heard that!" yelled Jackie.
"Yeah, I didn't want you picturing me as homeless, but Torchwood here was basically just Mickey, my mom and I figuring out something important to tell you when it was possible to go through to your dimension." she shrugged. "My mom suggested that we tell him that stars were beginning to disappear seven years ago, at a rate that it is a wonder why our sun was still there."
"Seven years?"
"That's at the least how long it takes for us to notice if a star is gone."
"Oh yeah. I must have forgotten."
"So,what do you think they are doing now?" Rose asked.
"Well, the Doctor must be wiping Donna's mind because a human body cannot sustain Timelord thought. There is simply never a combination of the two, because it is impossible to survive." The duplicate announced just before clutching his head.
"What's happening?" Rose questioned, worried that now that she got used to him they would be seperated.
"I DIDN'T THINK THAT RULE APPLIED TO ME!" bellowed the duplicate. He clutched his head more dramatically than Harry clutches his scar.
"Aw, shit." said Rose. "You are freaking kidding me."
His head exploded, raining Timelord brain everywhere.
Somewhere, in another dimension, the Doctor gave himself a huge facepalm.
