"We're going to negotiate now for the fifth season and beyond, so we're talking about those things now," said Reilly at the winter press tour on Jan. 8. A renewal of "Glee" prior to upfronts in May would also allow for a renewal of the Oxygen reality competition "The Glee Project."

"Glee," from co-creator Ryan Murphy, is currently in the midst of its fourth season, where storylines have taken the show's stars — and recent People's Choice winners — Lea Michele and Chris Colfer to New York City. Their respective characters, Rachel Berry and Kurt Hummel, have left Lima, OH, in attempts to turn their Broadway dreams into a reality.

The show is currently balancing two storylines — and shooting locations — with its original stars (Michele and Colfer) set in New York and new faces (Melissa Benoist, Jacob Artist, Becca Tobin and more) populating the halls of McKinley High School. Characters played by Darren Criss, Kevin McHale and Heather Morris, whose stories remains in Ohio, are scheduled to graduate from high school this season.

"I have to talk to Ryan [Murphy] and see where he's at right now," said Reilly of the show's storyline. "I don't know. I wonder — could it, and should it, naturally move [to New York City]?

"I do think if we can continue to follow a broad array of characters, it's like life: You have relationships, you have friends — they go off, their lives go on, and you get together and maybe you maintain a friendship, maybe you lose distance. I think we can do that within this world of people you followed." Reilly also noted that the plot leaves wiggle room for characters played by Dianna Agron, Mark Salling, Amber Riley, Naya Rivera and others — who are no longer series regulars — to return for multi-episode arcs.

"Some of them have moved on to other things or wanted to move on to other things," he said, "but they love the show, and this gives them a chance to come back and do an arc. It would be fun to continue that morphing."
