Who is Lourdes Puente from Dreaming in Cuban and what is their importance?

Celia's daughter and Pilar's mother, Lourdes lives in New York. Headstrong and determined, Lourdes is the main breadwinner of her family. She appreciates people who make their own wealth and is fiercely against socialism and the Cuban Revolution. Lourdes is not easily intimidated, as evidenced by her strong stance against her mother-in-law Zaida Puente and her reaction to the man who dislikes Pilar's painting outside her bakery. Lourdes and Pilar do not get along.
