The classic good cop, officer Gomez is Freddie's dad. He has no patience for the Tunnel Snakes and tries to make sure that Freddie doesn't have anything to do with them. This is hard, because there may not be any other boys Freddie's age in the vault.
Escape!: Gomez will be helping Stanley and Andy fight radroaches. Provided he is not attacked, he warns the Lone Wanderer that security is on the lookout for them. Gomez believes that James is innocent, and suggests leaving the Vault to search for the former.
Trouble on the Homefront: If he lives, Gomez will be the first Vault resident the Lone Wanderer runs into. Staying civilized with him will have him escort the Lone Wanderer to either Amata or the current overseer. If Allen Mack attacks while any guards are around, the guards will immediately come to his side to protect him. This includes Officer Gomez.
When returning to the vault during Trouble on the Homefront, he will have an entirely different voice type. This is due to him using the same dialogue as Officer Armstrong, who would appear in the quest fulfilling Gomez's role if he died during Escape!, since no separate dialogue was recorded with the voice actor, Gomez was simply given the same dialogue.
It is possible for Officer Gomez to be killed by Andy before the chance to talk to him. If Gomez gets in the way of Andy's flamethrower while they are fighting the radroaches, he will possibly die.
Officer Gomez will assist Vault Security if the Lone Wanderer is witnessed fighting any of its members (typically Officer Kendall). However, he will turn friendly again when combat ends if he is not harmed.
One of the destroyed homes in Springvale, closest to the elementary, has a letter in the mailbox from Vault-Tec addressing 'Mr & Mrs Gomez' that their family has been accepted into Vault 101 showing that his ancestral home was quite near to the vault.
No Karma is lost if he dies by the Lone Wanderer's hand during Escape!.
"Don't think I don't know it. Why do you think I'm letting you go? I guess you're trying to follow your dad... outside. Good gravy, if I didn't know what the Overseer would do if he caught you, I'd never tell you to try for it, but it's your only shot. You take care and I hope you find your daddy."
