There were a couple of surprises in Thursday’s ratings action, where ABC’s “Scandal” rose to a series high, beating CBS’ “Elementary” among young adults for the first time. And one hour earlier, the Eye’s “Person of Interest” appears to have gone ahead of the Alphabet vet “Grey’s Anatomy.”

CBS won the night overall behind top-rated show “The Big Bang Theory,” which should rank as the week’s No. 1 scripted program, and a season high for “Two and a Half Men.” The net’s station in Denver carried Thursday’s NFL game between the Broncos and Oakland Raiders, so the Eye’s numbers could be adjusted in the nationals.

According to preliminary national estimates from Nielsen, “Person of Interest” averaged a 3.2 rating/9 share in adults 18-49 and 15.0 million viewers overall in the 9 o’clock hour, rising 10% week to week for a season high and beating “Grey’s Anatomy” (3.0/8 in 18-49, 8.9 million viewers overall), which was in line with last week and near a season-low demo score. If it holds up in the nationals, this will mark the second time (and the first time this year) that “Person of Interest” has bested “Grey’s Anatomy” head-to-head in 18-49.

In its second season, “Person” is benefiting from a stronger showing at 8:30 p.m. by CBS for “Two and a Half Men” (4.2/12 in 18-49, 14.2 million viewers overall), which rose 5% from last week to easily lead its timeslot by retaining a strong 79% of its 18-49 lead-in from “The Big Bang Theory” (5.3/16 in 18-49, 17.4 million viewers overall). “Grey’s Anatomy,” on the other hand, continues to get little lead-in support from “Last Resort” (1.2/4 in 18-49, 5.5 million viewers overall), though it was up from its low of last week.

In the night’s 10 o’clock hour, ABC’s “Scandal” grew 14% week to week for a series high (2.5/7 in 18-49, 7.4 million viewers overall), topping for the first time CBS rookie “Elementary” (2.3/6 in 18-49, 10.9 million viewers overall), which itself was up a tick from last week. The retention for “Scandal” out of “Grey’s Anatomy” was a best-yet 83% in the prelims. “Elementary” continued to lead its network competition at 10 in both adults 25-54 (3.2/8) and total viewers.

Fox’s “The X Factor” (2.4/7 in 18-49, 7.7 million viewers overall) was down about 10% from last week, ranking second in its hour. And at 9, “Glee” (2.1/6 in 18-49, 5.5 million viewers overall) was down a smidge.

At NBC, “30 Rock” (1.1/3 in 18-49, 3.3 million viewers overall) was down 15% from last week but “Up All Night” (1.2/3 in 18-49, 2.9 million viewers overall) held steady behind it. From there, “The Office” (2.1/6 in 18-49, 4.2 million viewers overall), “Parks and Recreation” (1.5/4 in 18-49, 3.3 million viewers overall) and “Rock Center with Brian Williams” (1.0/3 in 18-49, 3.6 million viewers overall) were all up week to week.

CW’s “The Vampire Diaries” was on the low side (1.1/3 in 18-49, 2.4 million viewers overall), and “The Beauty and the Beast” dropped a bit (0.5/1 in 18-49, 1.4 million viewers overall).

Preliminary 18-49 averages for the night: CBS, 3.4/10; Fox, 2.3/6; ABC, 2.2/6; Univision, 1.5/4; NBC, 1.3/4; CW, 0.8/2.

In total viewers: CBS, 13.9 million; ABC, 7.3 million; Fox, 6.6 million; Univision, 3.9 million; NBC, 3.5 million; CW, 1.9 million.
