"Number Five" is the fifth episode of The Umbrella Academy's first season.
Five explains his situation to Luther. He used to work for a woman called The Handler, who recruited him from the future to become a member of the Commission, an organization devoted to preserving the current timeline. Cha-Cha and Hazel are chasing him after he broke his contract to try and stop the apocalypse. However, they now have to retrieve their briefcase from Klaus, who wound up in a war for ten months and destroys the briefcase in despair upon returning to the present.
Allison looks Leonard up and finds no record of him, but Vanya brushes off her suspicions and auditions for first chair. Luther accompanies Five as he arranges a meetup with the Handler, but it goes sideways when Klaus and Diego — who had previously failed to take them out — attack them. However, the Handler arrives and offers him a position back at the Commission, which Five accepts on the condition that his entire family survives. Off her medication, Vanya gets first chair and a Relationship Upgrade with Leonard, but she somehow appears to cause strange distortions. Pogo revives Grace and ensures that she'll keep something secret.
