Antonio and Gabriella went through a messy divorce and custody fight over their daughter Angelique. As the leader of a religious congregation, Gabriella excommunicated Antonio from the church and cut off contact with him. Afterward, Antonio got a job at Vault-Tec and used his position there to submit Gabriella's name as a potential overseer for Vault 94. He knew of the vault's true purpose and led Gabriella into a trap by disguising it as an opportunity for her congregation to establish a new, nonviolent community. Gabriella was ultimately chosen as the vault's overseer and its residents were massacred by outsiders in 2078.
