Trivia: Although he was intended to be the MCU's next major antagonist, season 2 of this show marked Jonathan Majors' final portrayal of variants of Kang, as Marvel dropped him from the role following a guilty verdict he received in December 2023 for assaulting and harassing his ex-girlfriend.
Trivia: Towards the end of the episode, Mobius mentions that a He Who Remains variant was defeated in an Earth 616-adjacent realm. This is a reference to the events of Ant-Man and the Wasp: Quantumania.
Trivia: We learn in this episode that prior to being abducted by the TVA, Casey was an inmate at Alcatraz named Frank. This is Frank Morris, whose story was the subject of the 1979 film Escape from Alcatraz, starring Clint Eastwood. He and two of his fellow inmates managed to escape the prison, but were never seen again, with one accepted theory being that they drowned in San Francisco Bay. His TVA abduction here provides an in-universe explanation for his disappearance.
