She worked as a collections representative at the same phone company as Robert. At home, she constantly gave most of her attention to Adam. He was attached to her hip all the time and slept with her at night. Evelina did not want to break this bond with her "little baby," but finally did it for his own good (and hers).
Evelina also had a starring role in the Family Update Special, inspiring Jo's various memories of past Season 1 visits.
She was 26 years old at the time and is now 39 years old in 2017.
