While The Goldbergs season 10 finale won’t have time to answer all the family sitcom’s lingering mysteries, the series does have a chance to wrap up one unfinished plot. Erica’s character arc in The Goldbergs hasn’t been overly consistent. When the nostalgic ‘80s-set sitcom began she was a popular high school student, but after graduation, Erica cycled through a series of potential jobs without settling on any specific vocation. At different points, Erica has been enrolled in college, a singer in a band, a prospective law student, and a full-time parent.
