The 9 o’clock on Tuesdays freshman comedy managed an initial 0.6 rating among adults 18-49 and 2.8 million total viewers for its April 12 finale, according to Live + Same Day data from Nielsen. Adding in a week of multiplatform viewing, the episode jumped 200% to a 1.8 rating, tying the show’s series high, and added 3.1 million viewers to reach 5.9 million total, per ABC.
