It was a down night for many shows on Tuesday night.
The Flash Season 7 Episode 3 concluded its Mirrorverse arc at a series low in the demo.
The series drew 1 million total viewers and a 0.2 rating -- down a tenth week-to-week.
Meanwhile, Superman & Lois came down to 1.2 million viewers and a 0.2 rating -- posting series lows.
Fear not, both shows are already picked up for next season and are solid performers when delayed viewing is factored in.
Over on CBS, a shocking episode of NCIS (9.5 million/0.8 rating) was steady, leading the night in total viewers.
FBI (7.9 million/0.7 rating) and FBI: Most Wanted (6.2 million/0.6 rating) were identical to their week-ago numbers.
NBC's rotation of This Is Us (4.8 million/0.8 rating) and New Amsterdam (3.6 million/0.4 rating) each came down to lows.
Looks like the sporadic scheduling of This Is Us is having a huge impact on the ratings. The series returned in October to 7.3 million viewers and a 1.4 rating.
NBC also aired original installments of Young Rock (2.9 million/0.6 rating) and Kenan (2.1 million/0.4 rating). Young Rock stands a shot at a second season, but the door looks to be closing on Kenan.
ABC's To Tell the Truth was steady at 3.7 million viewers and a 0.5 rating.
Holmes Family Effect did 1.2 million viewers and a 0.3 rating for FOX across two hours.
