In Season 1 - And the Rich Girl Problems, Caroline says that she only had two people help raise her. Estella from 1989 to 96, then Dominica from 97 until she returned to Guatemala, then no one. Suddenly now, Antonia Florentino was the only nanny she ever had.
The crying woman that Caroline hugs claims she was referring to a guy standing to the right of her. The man she was speaking of was barely in anyone's view and she walked straight to Caroline.
