But, later on, during the series finale, something amazing happens.
It’s been told throughout the show that Erin grew up an orphan and had never met her real parents, but at a the American Workplace Q&A during the series finale, an audience member came up and asked her about how she felt about her birth parents, and revealed to actually be her birth mother.
That and Joan Cusack is amazing in the small role she has as her mother, with Ed Begley Jr. playing her dad with adorable dance moves.
