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 you do not attack Gomez, he warns you that security is on the lookout for you. Gomez believes that James is innocent, and suggests you leave the Vault to find your father.
Trouble on the Homefront: If he is still alive, Gomez will be the first Vault resident you run into. If you stay civilized with him, he can take you to either Amata or the current overseer. If Allen Mack attacks you 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.
It's possible for Officer Gomez to be killed by Andy before you even have a chance to talk to him. If Gomez gets in the way of Andy's flamethrower while they are fighting the radroaches, he may be killed.
Officer Gomez will become hostile if he witnesses the player fighting any other member of Vault Security (typically Officer Kendall). However, he will turn friendly again when combat ends if the player does not attack him.
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. It seems the player is meant to assume these are the pre-War ancestors of Herman and Freddie.
"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."
