So, in the first teaser trailer for Fallout Season 2, we’re introduced to Mr. House, and we see him interact with Cooper Howard, the human version of Goggins’ character. It appears that this story from the past will overlap with The Ghoul and Lucy’s trip to New Vegas, and create parallel stories like we saw in Season 1.

The first trailer for “Fallout” Season 2 has been released, and it’s showing a first look at new cast member Justin Theroux playing the video game character Robert House in the fan-favorite location of New Vegas.

The Fallout season 2 teaser trailer debuted on Tuesday, Aug. 19, at Gamescom 2025 and gave fans a look at what's next for Lucy MacLean ( Ella Purnell ), Maximus (Aaron Moten) and The Goul/Cooper Howard ( Walton Goggins) in the post-apocalyptic Wasteland.
