As the weekly release of Fallout Season 2 unfolds, fans are buzzing with excitement—and some wild theories. One theory that’s caught fire surrounds Robert House, played by Justin Theroux. Viewers are wondering if he’s really the same charismatic billionaire from Fallout: New Vegas. After combing through clues, many suspect that the character could actually be Anthony House, Robert’s brother. So what’s the real scoop?
Let’s break it down in this guide, including some juicy details about Anthony House from the rich lore of Fallout.
Who Is Anthony House in Fallout?

In the Fallout universe, Anthony House is the half-brother of Robert House. Although we never meet him in the games, his presence is felt through scattered terminal entries. To give you a snapshot: Anthony never accepted Robert as his sibling and harbored a deep animosity towards him. Following a tragic accident that claimed their parents, Anthony ensured that Robert wouldn’t get a dime of their inheritance, taking control of the H&H Tools Company.
Over the years, Anthony led H&H to success, but his mental health slipped. He grappled with serious issues like paranoia and schizophrenia, which worsened as Robert began purchasing H&H shares through RobCo Enterprises. The constant fear of being ousted from the family business sent Anthony spinning into chaos.
Ultimately, things spiraled to the point where Anthony sealed off the factory and set up aggressive security to keep everyone away. In his last journal entry, he bizarrely signs off as “Alexander House,” which starkly highlights his deteriorating state of mind.
Is Anthony House in Fallout Season 2?
No, Anthony House is not in Fallout Season 2. Multiple cast interviews and details from Amazon Prime’s Fallout page confirm that Justin Theroux’s character is indeed Mr. House, not his troubled half-brother. Just so you know, Rafi Silver serves strictly as a body double for Robert and has no familial ties outside of that role.
But why did fans jump to this theory? It boils down to that very first scene featuring Mr. House in episode one. He casually mentions the H&H Nail Gun—an obscure reference that even die-hard enthusiasts didn’t see coming. Then, there’s his chilling action of orchestrating the murder of three people in an alley while experimenting with a mind control chip.

This behavior clashes strikingly with the vision fans have of Mr. House. In Fallout: New Vegas, he explicitly states that he values free will and doesn’t want to infringe on others’ autonomy. Knowing that the pre-war House is seemingly conducting field tests on a mind control chip leaves many fans perplexed.
This contradiction led to speculation about whether Robert House might actually be the deviously clever Anthony. Rest assured, that theory isn’t true; Mr. House in Fallout Season 2 is the same character from FNV.
What is the relationship between Robert and Anthony House?
Robert and Anthony House are half-brothers, with Anthony resenting Robert after their parents’ tragic death. This resentment led to Anthony’s attempts to cut Robert out of their family legacy.
Will Anthony House appear in future episodes of Fallout Season 2?
There are no indications that Anthony House will appear in future episodes. The current narrative focuses on Robert House as a distinct character.
What do fans think of the theory about Anthony House?
Many fans are divided; some enjoy the intrigue and complexity it brings to the story, while others feel it distorts the original character’s established legacy.
How does Anthony House’s behavior reflect his mental state?
Anthony’s paranoia and erratic actions underscore his psychological decline, showcasing the impact of living in the shadow of his brother, whom he views as a threat.
