Things got pretty hot in the season finale of “Chicago Fire,” and the ratings for the NBC drama were equally on fire.

Last night’s finale scored a 1.2 rating among adults 18-49 and 9.3 million total viewers, which equals the series’ largest ever Live+Same Day audience, matching an episode from way back in 2013. The “Chicago Med” finale scored a 1.1 and 9.2 million viewers, its second largest viewership tally of the season. “Chicago P.D.” rounded off the night for NBC with a 1.1 and 7.9 million pairs of eyeballs, a 5-week high.

Fox still managed to win the night overall, despite “The Masked Singer” ticking down significantly with a sing-along episode. The wildly popular singing competition show scored a season low 1.7 rating and 6.7 million total viewers, down from a 2.1 and 8 million last time around. The season finale of “Lego Masters” came in even on the penultimate episode at a 1.2 rating. Just under 4 million viewers tuned in, the Will Arnett-hosted show’s largest audience since the series premiere.

Over on CBS, “Survivor” came in even at a 1.5 rating and 8 million total viewers. Reruns of “SEAL Team” and “S.W.A.T.” delivered a 0.5 and a 0.4 respectively.

Jimmy Kimmel’s edition of “Who Wants to Be a Millionaire” plummeted in the ratings on Wednesday night, falling 45% to a 0.6 rating and 3.9 million total viewers. “The Goldbergs” also lost a little ground, falling to a 0.8 rating and 4.4 million viewers. “Schooled,” “Single Parents” and “American Housewife” all came in roughly even episode-to-episode, scoring a 0.7, a 0.6, and a 0.5 respectively.

On the CW, “Riverdale” aired its “Hedwig” musical episode to a 0.2 rating and 553,000 total viewers, followed by the season finale of “Nancy Drew” with a 0.1 and 489,000 viewers.
