Well Leighton said they were filming in Paris, in stills from the finale she is in her room with Serena and suitcases and he father lives there, so I think it's safe to say its Blair (at least, others could be there too).

Maybe...who knows?

I wish that Blair and Chuck were going together, but they're probably not :(

i think that Serena & Blair is there together maybe?

and Chuck is going after her... i'm so damn sure!!!!!!! *cue to cliffhanger*

I reckon Eric ;)

B and S!

I think its either Blair or Jenny, maybe Jenny is going to Paris to work for Elenor more? IDK. I just picked B because he dad lives there.

Stephanie Savage said at least three key characters - Blair, Serena and Chuck will be going.
She also said “Serena and Blair are finishing up their fabulous summer vacation when someone from home mysteriously shows up in town,” Savage explains.“They need to solve this mystery, or else return to a New York that’s a very different world.”
But theres no word on whether this third person is Chuck, or another character yet to be revealed.

B & S for sure.

^^^Aw, so most likely Blair goes {with Serena} to get away, and Chuck comes after her <3

Blair and Serena go and if chuck does go after her then i might have to rethink my couples for endgame!!
