Rita was the Pfefferman children's nanny, until it was discovered she was having a sexual affair with Josh Pfefferman. It turns out later in Season 2 that Josh and Rita had a child, named Colton, who appears as a 17-year-old later in the show. He briefly lives with Josh and Rabbi Raquel but ultimately goes back to live with his religious adoptive family.
After she and Josh make their peace in Season 3, later in the episode she walks up to the top floor of a nearby mall and jumps, dying from suicide. She is portrayed by Brett Paesel.
