Corrected entry: In this episode, Vint is asked to marry an alien woman to help her get her green card. By this point in the season, he is already married to Naomi. Is it legal for a man to be married to two women at once?
Correction: "Mama's Family" episodes were aired out of order. "Alien Marriage" was the second episode produced (production code 7002) while the "The Wedding" episodes were the 6th and 7th episodes produced (production code 7006/7007). Therefore, in the context of the show as written and produced, Vint isn't married. When watching in order as the episodes aired, this would be a flashback episode.
Correction: Vinton is not married to Naomi in this episode. This may be episode 11 in sequence, but the events are out of sequence. Naomi visits Mama in the backyard, and she still has her house. She is not engage to Vinton. It is a continuity error.
Vent married Naomi in episode 3 season 1. The Alien Marriage was season 1 episode 11.
