This Monday's notable numbers:

8 pm/ET
Trailing Deal or No Deal, Prison Break (9.73 million total viewers) was up 340K week-to-week. CBS' The Class was dismissed by a typical audience of 8.77 million.

9 pm
The conclusion of Heroes' second arc (14.9 million, up 630K) - and the last fresh episode until, like, forever - delivered the series' largest audience since Dec. 4, outdrawing both a Two and a Half Men repeat and a thus-handicapped Rules of Engagement (12.6 million, down 1.1 mil). Fox's 24 (13.01 million) was up 200 thou.

10 pm
Placing well behind a CSI: Miami repeat (14.27 mil), NBC's The Black Donnellys (7.04 million) lost 1.38 mil from its premiere, but is still 600,000 above Studio 60's last tally. What About Brian had one of its weaker outings, with an audience of just 4.78 mil (slipping 620K).
