25 Umbrella Academy Season Two Fan Theories
Reginald Is Five
A theory that is in many, many Reddit threads is summed up very concisely here by easyjf. Reginald Hargreaves is Five, who went back in time to create the Umbrella Academy in order to prevent the apocalypse he had seen in the future. Alternately, they believe he could be a member of The Commission trying to make sure the apocalypse happens. The latter is more likely than the former, but a lot of fans believe that Reginald is secretly Five as an old man… even though we’ve already seen Five as an old man in flashbacks, and he looks nothing like Reginald.
