Ariana is the 8-year-old daughter of Mateo, a former colleague of Caleb's. Her mother is Renata. Her youngers brother are Alonzo and Dante. Mateo is rather lenient with Ariana, compared to how strict he is with Alonzo.

Ariana comes to the Fairns' Fourth of July barbecue (2013) because her parents are considering becoming Wynter's emergency caregivers. She wears a dress her mother made, and becomes upset when a fight with Alonzo puts a grass stain on it. She complains about the food, so Bea makes her chicken nuggets.

She always wins at Monopoly.

Ariana appears in 02 Out of Tune.
