NCIS returned Tuesday from its three-week break to a season low, while Cougar Town saw its best numbers in a month.

The drama drew 18.6 million viewers and a 3.3 in the adults 18-to-49 demographic — its lowest rating all season — but, as usual, it was still the night's top show. NCIS: Los Angeles (16.06 million, 2.8) also slipped to tie its season low, but Unforgettable (11.32 million, 2.1) inched up two-tenths to give CBS the win.
