"Fallout" Season 2, which continues the adaptation of the blockbuster video game, "Fallout," is back with its premiere episode. Who are the principal cast members featured in the show?

Fallout Season 2 is finally almost here, and fans are all ready to go back to Graham Wagner's post-apocalyptic drama.

Fallout has returned to Prime Video with its second season. The show continues its post-apocalyptic story with familiar faces and new dangers. Season 2 episode 1 is titled The Man Who Knew. It picks up right after season 1 and sets up a darker, more serious journey through the Wasteland.

SPOILERS for Fallout Season 2 Episode 1: The Man Who Knew to follow: The last time we saw Lucy MacLean (Ella Purnell), The Ghoul aka Cooper Howard (Walton Goggins), and beloved pup CX404, their situation looked dire.

The combination of supernatural elements with horror always brings forth a layer of complexity, as in Castle Rock Season 1.

Both Episode 1 and Episode 2 will be released on December 10. Then, new episodes of “Percy Jackson and the Olympians” premiere on Disney+ each Tuesday through January 21, 2026. “Percy Jackson and the Olympians” Season 2 Episode 1 will be available on Disney+ from 12 am Pacific Time (PT) on December 10, 2025/3 am Eastern Time (ET).

In particular, thanks to music supervisor Trygge Toven, the first episode includes one hell of a needle drop: "Big Iron," Marty Robbins' iconic 1959 Western ballad, a song known to Fallout fans as associated with the game Fallout: New Vegas.
