All he can think is that this is so very very wrong.
Why is this wrong? Well, for one thing, he'd been walking to "work" (if you could call puttering around aimlessly all day in a Torchwood lab
work) when there had been a bright flash and loud bang, and then suddenly he was on a different street. Well, no, it was the same street, but it looked different. And when he looked up, there were no Zeppelins.
And then when he ran down and around the corner, the Torchwood facility he and Rose worked in (not the main building, Rose couldn't stand the offices, they had a couple squatty buildings and an aircraft hanger out near Chiswick) was gone.
Not destroyed, not removed, not invisible. Just... not there. As if it had never been there. There was a row of bloody
flats, for Rassilon's sake.
"Oh, this is bad, this is very
very bad..." he muttered to himself, turning in circles, frantically looking for some sign that this was all a prank or something.
