Last, but not least, this is supposed to be what the script says during the scene with Blair waiting for Chuck at the airport thing, taken from this website:
"SERENA AND THE MYSTERY GUY:
Serena: I was just about to kick off my isolation, but I suppose I could postpone it temporarily. You wanna get an iced coffee?
He nods, sure, and they head off…
EXT. HELIPAD – DAY
Blair steps out of the limo. She approaches a good-looking guy, Ben Simmons, 21.
Blair (motions to the chopper): Excuse me? Is that the Bass helicopter?
Ben: No, it’s not here yet. (smiles) You going to do a powerpoint presentation for Burlesconi, too?
Blair: No. I’m a guest of Chuck Bass.
Ben: I’ve heard a lot about him. If he’s anything like his father, he must be terrifying.
Blair: He’s not all bad. He’s taking me to Tuscany.
Ben: Very romantic. So, where is he?
Blair: On his way. I just wanted to get here early. (beat) I like the jumpseat.
Ben: Nothing. It’s just…I like the jumpseat. I have this thing about flying and it makes me feel more…
Blair (finishing his sentence): In control. Yeah.
EXT. HELIPAD – DAY
Blair stands. The helicopter now there. A text. She reads…face falling…
Ben: Everything okay?
Blair (most of this is scratched out): …I guess… He can’t make the flight…
Ben: Well, I’d be willing to flip you for the jumpseat.
Blair (considering): Well… It’s a private jet…And I do like when the ladies make those cookies for you. (smiles, shrugs) What’s ten hours? Absence makes the heart grow fonder.
Ben: Or fungus.
Blair: Jokes like those- This could be a very long flight.
Ben smiles, takes her hand luggage for her and they head for the helicopter to take them to the airstrip…"
