Allen Mack

Allen Mack is a resident of Vault 101. He is the husband of Gloria Mack and the father of three children. Wally Mack is a member of the Tunnel Snakes, a group of teenage gangsters. The names of his children are Steve, Susie, and Wally. Mr. Mack is a close ally of Overseer Alphonse Almodovar.

In the 2260s, Mr. Mack, at his son's birthday party, requested that Andy perform magic tricks.

When the Lone Wanderer is escaping the Vault, Allen slams on the window of his vault room, calling for the guards and saying that everything is the Lone Wanderer and James's fault. You can see Gloria Mack sitting at a table behind Allen, with her hand on her head.

If the player killed the Overseer during their initial escape, Allen will be elected the new Overseer who is even more oppressive than the previous one and cannot be reasoned with.

One of his combat lines include "The Overseer will hear about this!" even after he becomes the Overseer himself should you happen to have Amata's dad killed, obviously a tidbit of inconsistency that the developers forgot about.
