Warning: Spoilers ahead for The Goldbergs season 10, episode 17.While Barry has always seemed immature throughout the show’s run, The Goldbergs season 10 has proven that the character could redeem himself before the series finale. Barry Goldberg is a complicated character. Initially introduced as the lovable if lunk-headed older brother of the show’s narrator Adam, The Goldbergs supporting star soon developed an increasingly absurd personality. When Adam and Barry were both teenagers, Barry was his dim-witted but well-meaning older brother while Erica was his more sardonic and comparatively streetwise sister. However, by The Goldbergs season 8, this dynamic had shifted a lot.
