Gossip Girl executive producer Stephanie Savage has claimed that the upcoming season finale has a big impact on the characters.
Speaking to TV Guide magazine, Savage teased that Chuck (Ed Westwick) and Blair (Leighton Meester) will have an important scene at the Empire State Building.
She added that one storyline involving Dan (Penn Badgley) will have an impact on Nate (Chace Crawford) and Serena (Blake Lively), while Dorota (Zuzanna Szadkowski) will give birth to her baby.
"The finale is a game changer," Savage said. "An old friend returns to the city, several leave it for the summer... and one of them might not come back."
Savage also explained that Serena's father Keith van der Woodsen, played by William Baldwin, will have an important role in the episode.
She said: "The events that he puts into motion [are driving] us to the end of the season, culminating with the finale cliffhangers."
Gossip Girl continues Mondays at 9pm on The CW in the US and Wednesdays at 8pm on ITV2 in the UK.
