CBS' Monday block, still in repeats, brought in a 2.3 in adults 18-49, also losing to Fox in total viewers with 8.1 million. A repeat of Two and a Half Men (3.0 rating in adults) was the night's strongest broadcast across the board.

The Bachelor dropped just 4 percent after last week's jump, pulling a 2.6 in adults 18-49 for the two-hour broadcast. Adding a repeat of Castle, ABC averaged a 2.2 rating for 18-49-ers and 7.6 million for the night.

Who's Still Standing? aired even with the previous week's 1.7 in the demo, while an encore of Fear Factor pulled a 1.5 in 18-49-ers and the debate-less Rock Center With Brian Williams dropped 50 percent from its super-sized telecast last week for a 0.8. Overall, NBC brought in a 1.3 in the demo and 4.6 million viewers.

On the CW, Gossip Girl's episodic centennial marked its second most-watched episode of the season, up 17 percent in adults 18-49 for a 0.7. Hart of Dixie reaped the benefits climbing 20 percent in adults for a 0.6 -- also the net's average showing in the 18-49 demo for the night.

More to come.
