House stars Hugh Laurie, Omar Epps, Amber Tamblyn and the show's producer David Shore have offered more hints about its swansong.
Speaking to TVLine at the series wrap party, Shore expanded slightly on the episode's title 'Everybody Dies'.
Shore teased: "It's fundamentally true, and it's also a nice reflection on the name of the pilot, which was 'Everybody Lies'.
"It'll become clearer as we get closer to [the finale] what's going on. But it's certainly House assessing his life, and his future."
Laurie, when asked to describe the episode in a word, chose "uplifting", while Epps hinted that the phrase isn't simply a title, but is not necessarily literal either.
"I won't say it's just the title," Epps later said. "But the heart of the show is about the notion that everybody lies."
Some specifics also came out about the episode's two confirmed character returns. Tambyn revealed that her return as Martha Masters is "a quick appearance".
On Thirteen's (Olivia Wilde) return, Shore said: "She comes back to give House a little advice. She intervenes with House and Wilson."
Robert Sean Leonard spoke recently about the fact that Cuddy (Lisa Edelstein) will not return for the final episode, suggesting that such a comeback would feel unnecessary.
The series finale of House airs on Fox on May 21.
