In One Day at a Time's first season, Penelope (Justina Machado)'s ex-husband Victor (James Martinez) was an absent, alcoholic father who rejected Elena because of her sexuality, even refusing to dance with her at her quinceañera. In season three, he has a complete resolution, returning to his kids' lives and even inviting Elena to have their dance together at his wedding to his new wife Nicole (played by showrunner Gloria Calderón Kellett). It seems that Penelope and Victor are in a much better place to coparent now, so an increased fatherly presence in season four would be a very welcome change.
