Read on for more!

What’s it like to be celebrating the end of the 5th season?

It feels great. It’s really exciting. I think it’s an amazing episode. As everyone’s probably already heard, we’ve got our order for season 6, which will be our final run so we’re really launching what are going to be those final stories in that episode.

You love having some fun really fun guest stars on the show. Elizabeth Hurley was such a hit this season. What is your dream guest star for season 6?

We have some guest stars that we are cooking up for next season that I’m not going to say who they are but we are also really going to focus on our core characters for next year. When we really have only so many episodes left, we really want to make sure that we’re telling stories with Serena, Blair, Chuck, Dan, Nate, Rufus and Lily and that our core family gets all their screen time.

Since we’re here at the finale of season 5, how far in advance in season 6 do you have to be thinking and how did that play into you developing this finale episode?

We definitely had some ideas in mind and the writers came back a week and a half ago so we’re already working on season 6 and figuring out what those episodes are going to be, what the first episode back is gonna be. It’s fun.

Going into the last season, are there certain things you want to accomplish or touch base on from previous seasons?

Yeah I think definitely that’s something that we talk about a lot and getting ready for season 6, everybody re-watched the pilot and we talked about what our favorite episodes were and our favorite dynamics. It’s bittersweet. It’s very exciting. As a writer, I think your impulse is to move your story forwards and to bring things to completion. As a television producer, your job is to make the show last as long as humanly possible. Those final 10 will be really sad and weird when it’s over. We want to make sure that the last 10 episodes, we’re leaving it all on the floor. We really want them to count and to be really special.

Are there 10 or 11 episodes in the final season?

That might change but right now they’re saying 10 and a retrospective. The CW will clarify that on Thursday.

What point in the season did you know that Chuck and Blair might be reunited in the finale?

I don’t know that it was ever a question at any point in the season particularly. I think it was just a question of arcing out that relationship so that it ended in a place where it was Blair coming to declare that she was in it to win it with Chuck and leaving that as the question of season 6.

Can you tell us anything about season 6? Who is coming back? What are some of the storylines?

We’re definitely focusing on our core characters but kind of the gang that you see in that final act are going to be the main players when we come back.

Does that include Georgina?

It does include Georgina.

Do you already know how it’s going to end for everyone?

We know a lot of things.

It seems like you’re going back to Season 1 almost with Serena – who she was before that. Is that something you are interested in exploring? Maybe showing Serena before we see the reformed side of her?

Yeah. Obviously it’s a signature of the show to do echoes of previous episodes. I think that’s the third time we’ve done the train shot. We did it with Serena. We did it with Jenny. Chuck had a train shot in the Paris episode but kind of having Serena leave town as we saw her come back into town in the pilot was definitely delivered in that idea where she’s now feeling like she’s lost Blair, she’s lost Dan. She’s sort of all by herself again. That’s going to put her in a pretty precarious emotional situation when we start season 6.

What can you say about the love Rufus – Lily – Bart  triangle?

I think that’s something that is really exciting for season 6 — to see how that is going to shape up and what’s the endgame for those three characters. Rufus and Lily’s marriage has been relatively stable for a couple years and it’s just recently in the last sort of story arc that we did - with Lily and her mother dying and with the will and Ivy and the war with her sister - that certain aspects of her personality that we are all very aware of and that have been with us since the beginning are starting to solidify in a way that’s made Rufus uncomfortable and made him question what that relationship is really about. Then with him making this final gesture towards her that we saw in the finale of wanting to save the marriage and Lily rejecting that, I think is going to put them all in a really interesting spot for next year.

It seems like Blair at the end of this episode is completely committed to getting Chuck back. So are Dan and Blair’s romantic side done or are you guys going to still toy with it in season 6?

I never like to say yay or nay to that type of question but we crafted the last act of that episode to set us in a certain direction next year.

Is she going to find out that Dan cheated on her or does that not matter anymore now that she is talking to Chuck?

Well if somebody had a sex tape on their phone on Gossip Girl and they said that they deleted it but you never really saw that it was deleted…

You said that Georgina is going to play a big part next season. Does that mean that Michelle [Trachtenberg] is going to be in more episodes? All 10?

I can’t confirm that but we’re talking about it.

Ivy is a regular now. Is Lola a regular now too?

I think that Ella Rae [Peck] got a pilot for NBC so we’re very excited for her but sad for ourselves. It seems like she won’t be available to do the show next year.

Obviously Nate is on to who Gossip Girl might be. Is that going to play a huge part in the final season?

It’s definitely going to be something that Nate is going to seize on and be tracking down. We thought he had pretty good detective skills this year so we’re gonna keep using them.

Will Nate finally find a real love?

That’s going to be one of the series questions. I think when we met Nate, way back when in the pilot, he was someone who was really questioning what this world held for him, dating and pining for Serena – where was it all going to end? I think that’s a big part of his series arc that we’ll be exploring next year.

Do you guys know at this point whether or not you will unmask Gossip Girl by the end of the series?

The unmasking of Gossip Girl is something that has larger implications to the franchise beyond just our series. That reveal requires conversations at the highest level of the octagon.

Will Josh Safran have any involvement in season 6 or is he fully involved in Smash land now?

He’s off getting smashed.

Are you guys going to do anything like a new format, a musical episode, or anything different for next season?

It’s funny because if we only have so many episodes left, we’ve been making a list of what are those things that we might want to do on our series that we haven’t done yet and we’re definitely exploring every crazy option of ways to tell our show.

If Gossip Girl is revealed next season. Is it going to be who was in the video or is that another Nate clue?

Wait and see. Nate has a lot of clues to figure out before he comes to any conclusions.

With Dan’s new book, is he completely out to get the Upper East Side at this point?

How did it seem at the end of the finale? When you call in Georgina Sparks, it’s serious business!
