Fallout Season 2 Episode 7 reveals Diane Welch's severed head as Vault‑Tec mainframe

Pcgamer reports that Fallout Season 2 Episode 7 ends with Lucy finding congresswoman Diane Welch's severed but still‑alive head in a jar, wired into Vault‑Tec's mainframe beneath New Vegas.

The episode also opens on a flashback to Overseer Steph's internment and follows Hank MacLean's workforce mass‑producing mind‑control devices — Hank explains the dial dictates how much amnesia a subject experiences while the mainframe implants "new ideas." Lucy vacillates about destroying the program after seeing a reprogrammed former Legionnaire behaving politely, later handcuffing Hank to a stove and setting off again toward the mainframe. Elsewhere, Max, The Ghoul and Thaddeus clash over a cold fusion diode, Max decapitates a deathclaw in power armour but other deathclaws smash Freeside's gates, and a Cooper Howard flashback shows him giving the diode to the President before he later plugs the same device into New Vegas and sees Mr. House's computerized face — leaving it unclear whether House is actually alive or merely a digital backup.

The episode runs barely 43 minutes and leaves several questions unresolved: the true status of Mr. House, the fallout of the deathclaw breach in Freeside, and what Lucy will ultimately decide as the season reaches its final episode.
