Who is Robert House in Fallout 2? Character analyzed

Robert House founded RobCo Industries, supplying robotics and tech to the military and civilians. He predicted the Great War and installed missile defences around Las Vegas, saving most of the Strip. 

In Fallout: New Vegas, set in 2281, he exists as a preserved brain connected to a computer network in the Lucky 38 casino, controlling securitron robots.

He seeks to rebuild civilization under his technocratic rule, opposing factions such as the NCR and Caesar's Legion. Players can support him for an independent New Vegas ending or eliminate him.

In the TV series' season 2, House is a central antagonist as the story moves to New Vegas. Justin Theroux portrays the pre-War House as a cold, calculating billionaire who prioritises progress over human life. 

The premiere reveals a twist: Rafi Silver reprises his role as a public-facing body double for House on TV and at events, while Theroux plays the real House operating from the shadows. This adds a new layer to the lore, showing House's extreme caution and control.

Episode 1 introduces a brain-computer interface device, a neck implant for mind control, which House develops and tests. He demonstrates it on a worker, forcing obedience and then overloading it to the point of fatal exhaustion.

This technology connects to post-War elements, including devices found in vaults and Hank MacLean's ongoing experiments. 

Hank contacts someone in New Vegas, implied to be House, vowing to complete his work. Trailers suggest House survives into the present via life-extension tech, ruling New Vegas from the Lucky 38.

Theroux's performance highlights House as a pragmatic futurist, echoing real-world tech leaders, with subtle mannerisms making him charismatic yet ruthless.

What happened in Fallout season 2 episode 1?

Episode 1, titled "The Innovator" or similar references to innovation, opens pre-War with protests against RobCo. House (Theroux) enters a bar, provokes unemployed workers, and demonstrates a prototype neck implant that forces obedience- overloading it causes a fatal explosion.

This demonstrates his disregard for human life in the pursuit of progress.

In the present, Lucy and The Ghoul travel toward New Vegas, handling threats along the way. Lucy shows growing toughness. Flashbacks explore Cooper Howard's pre-War life and potential links to House.

Hank arrives in the Mojave, accesses Vault-Tec facilities, and works on refining the control tech, leaving a message about completing House's vision.

Vault dwellers deal with internal issues. The episode concludes, setting the stage for New Vegas' arrival, faction conflicts and House's lasting impact through technology.
