Talia celebrated Jewish holidays with Dina, giving her an apple dipped in honey for the new year of the Hebrew calendar. During the early 2030s, Talia and Dina lived in New Mexico.
Talia was killed prior to 2038. The incident left Dina vengeful, once telling Ellie that she would do worse than what Tommy Miller did to one of Joel's killers if she ever found them.
