 Pretty Little Liars star Sasha Pieterse hinted at some twists, and a surprising guest star in the show’s upcoming season finale.

“Adam Lambert makes an appearance, which was such a shock to us because he is so amazing!” Pieterse said. “And the only other thing I can say is that it takes place on a train. And it’s crazy shocking!”

Revenge star Christa B. Allen mingled and hugged co-star Gabriel Mann, who told THR that the beginning of the show’s second season will “leave viewers reeling.”

Thomas Sadoski, star of HBO’s The Newsroom, gushed about creator Aaron Sorkin, referring to him as “genius.”

“[Sorkin’s] characters are so multi-dimensional and so engaging,” said Sadoski. “Once I read the script, I knew I had to do it.”

Sadoski also told THR that his character, Don Keefer, was originally written as two characters, but when Sorkin heard his first table read, he decided to combine them into one.

“It’s a bit intimidating knowing that Aaron Sorkin essentially created a character for me,” said Sadoski. “But so far, I think it’s turned out pretty well.”
