The episode matched The Flash’sseason highs in the both 18-49 and men 18-49 (1.8/6) demographics, and ranked first in its hour in men 18-34 (1.3/6) and second in 18-34 (1.1/5).
iZombie followed The Flash with 1.4 million viewers overall and a season high in adults 18-34 (0.7/3) and in men 18-34 (0.7/3).
Meanwhile, ABC’s Marvel's Agents of S.H.I.E.L.D. scored low with 1.3/4 in 18-49, and 3.5 million viewers overall."
Not sure how I feel about Flash and Agents of S.H.I.E.L.D going head to head. I would hate to see Agents of S.H.I.E.L.D get cancelled b/c it can't beat Flash.
