NBC has swept another Monday in young adults with “The Voice” and “Blindspot,” while a pair of dramas — CBS’ “Scorpion” and Fox’s “Lucifer” — looked solid in wrapping their seasons.

According to preliminary national estimates from Nielsen, “The Voice” was at a Monday season low (2.1/7 in 18-49, 9.6 million viewers overall), down a tenth from last week, but ruled as Monday’s No. 1 program in most demo categories. “Blindspot” followed at 10 p.m. (1.4/5 in 18-49, 5.7 million viewers overall), up a tenth and again winning its hour in 18-49 and 25-54 (1.9/5). The rookie drama again last week had Monday’s biggest “Live+3” lifts, rising by 0.90 (or 69%) in 18-49 rating (1.31 to 2.21) and by about 2.9 million total viewers (5.5 million to 8.4 million).

At CBS, “Mike & Molly” (1.3/5 in 18-49, 6.9 million viewers overall) returned to the schedule as it begins its final weeks of telecasts, down 0.3 from its prior original on a Wednesday in February but matching last week’s “Supergirl” finale in the timeslot. “Mike & Molly” was followed by a special repeat of “The Big Bang Theory” (1.2/4 in 18-49, 6.2 million viewers overall) and the second-season finale of “Scorpion” (1.6/5 in 18-49, 8.8 million viewers overall), which was up a tenth from last week in both 18-49 and 25-54 (2.4/6) while standing as the night’s most-watched scripted program overall. “NCIS: Los Angeles” closed out the night (1.2/4 in 18-49, 7.8 million viewers overall), also up a tick from last week in demos.

Fox’s “Lucifer” wrapped its first season with a 1.3/4 in 18-49 and 3.9 million viewers overall, matching last week’s demo average even though it had a repeat “Gotham” lead-in this time (0.6/2 in 18-49, 2.0 million viewers overall). Heading into last night, the already-renewed “Lucifer” was one of the season’s top new dramas in Live+3 rating among adults 18-49, averaging a 2.3 in the demo and 6.95 million viewers overall.

ABC’s “Dancing With the Stars” (1.8/6 in 18-49, 11.7 million viewers overall) picked up two tenths from last week’s season low, while “Castle” (1.1/4 in 18-49, 6.4 million viewers overall) rose a tenth as well.

At CW, the time-period premiere of “Reign” (0.3/1 in 18-49, 1.0 million viewers overall) did slightly better than former occupant “Crazy Ex-Girlfriend.” It was followed by “Jane the Virgin” (0.4/1 in 18-49, 0.8 million viewers overall), which was about average.
