Your favorite chaotic brother (Drew Tarver) and sister (Heléne Yorke) duo is back for a second season... and so is their mom. Pat Dubek (Molly Shannon) is basking in her newfound limelight as a daytime talk show host, thanks to the continued fame of her youngest son, Chase Dubek (Case Walker), who's new enrolled at NYU. Cary finds himself the host of a niche gay web-series, Brooke switches "clients" (hint: it's her mom), and Streeter Peters (Ken Marino) gets closer than ever to the Dubek clan as a manager-and-maybe-more.
