Amazon’s Fallout TV show has been praised for its use of elements and Easter eggs from the series, as well as its standout characters. Thaddeus is a side character in the show, which centers around the MacLean Bunch from Vault 33. The first season, consisting of eight episodes, impressively weaves together individual storylines and ensures that no character feels underdeveloped. Thaddeus is a fellow initiate in training for the Brotherhood of Steel, serving as a bully who makes life difficult for the main character, Maximus.
Their conflict escalates when Maximus assumes the identity of fallen Brotherhood Knight Titus, leading to a series of unexpected events for Thaddeus. As Maximus seeks all the glory for himself and impersonates Knight Titus, he opposes the Brotherhood of Steel sending him a new squire – Thaddeus. However, their confrontations lead to a struggle, resulting in Maximus crushing Thaddeus’ foot with his Power Armor suit. In a separate incident, Thaddeus encounters the Snake Oil Salesman, who offers him a serum promising to heal his foot and provide immunity to radiation.
After an arrow accident and a discussion with Maximus, Thaddeus flees the Brotherhood, leaving his fate uncertain. The show leaves open the question of whether Thaddeus is becoming a Ghoul due to the effects of the serum, leading to speculation and fan theories about its origin and implications from the games.
