Nothing is known about Ava's life before the apocalypse, except she had a mother, husband, and was pregnant.
Ava is among the dozens of refugees to arrive at the Rosarito Beach Hotel begging to be let in. After her mother pleads for her daughter to be let in, due to her pregnancy, Strand arrives and announces to everyone that they will be taken care of. The next morning, Ava is going into labor and while Strand initially refuses, he helps deliver Ava's baby, in which she names Victor, after Strand.
Strand and Daniel arrive later at the hotel and begin for searching for Ofelia, but they find the hotel abandoned and overrun with walkers, and no signs of Ava or the refugees. Strand assumes that the hotel must have been taken by the dead. Whether or not Ava survived is unknown.
- Ava is the second pregnant survivor encountered in Fear The Walking Dead, the first being Vida.
