First appearance of Sonia, Gloria's sister. She is played by Stephanie Beatriz.
Elizabeth Peña plays Sofia Vergara's mother even though she is only 12 years 9 months, 17 days older.
In this episode, Jay tells a story of how he met Gloria at a diner. In a previous episode, Jay says that he met Gloria at a wedding.
The scene between Gloria and Sonia when Gloria asks Sonia if she is dating anyone is very similar to an episode of Friends. In one episode Rachel asks her sister if she was dating anyone and her sister responds with virtually the same thing Sonia does by asking if they remember their old boyfriend and then saying it's their old boyfriends dad.
