THE DOCTOR: Oh, that’s more like it! That’s the New we had last time. This must be the lower levels. Down in the base of the tower, some sort of under-city.
MARTHA: You’ve brought me to the slums?
THE DOCTOR: Much more interesting! It’s all cocktails and glitter up there. This is the real city.
MARTHA: You’d enjoy anything.
THE DOCTOR: That’s me. Oh, the rain’s stopping! Better and better!
MARTHA: When you say “last time”, was that you and Rose?
THE DOCTOR: Um – yeah. Yeah, it was, yeah.
MARTHA: You’re taking me to the same planets that you took her?
THE DOCTOR: What’s wrong with that?
MARTHA: Nothing. Just – ever heard the word “rebound”?Doctor Who (3x03: Gridlock)
shut yer damper hole, martha.
So it’s not a flare gun, it’s the sonic screwdriver he shoots in the trailer? Or has this already been established?

Since the whoever wrote that script needed it to, I guess. lol but maybe this is where he has to build the new one that’s in SITL/FOTD. New Doctor, new TARDIS, new screwdriver and all ‘at.
