Ratings: Chuck Hits Season Highs, Grimm Surges, Fringe Stays Flat

Chuck is ramping up to go out with a (all things being relative!) bang, gaining 22 percent in its penultimate week to spy two season highs: 3.85 million total viewers and a 1.1 demo rating.

Lead-out Grimm, in turn, registered bumps of 28 percent, drawing 5.9 million viewers and a 1.8 — its best numbers since Nov. 4. and a tie (with 20/20) for Friday’s best demo rating.

Friday’s other piece of fresh genre-TV fare, Fringe, had to settle for holding steady with a 1.1 rating whole inching up 11 percent in total audience (to 3.2 million viewers).

Elsewhere on the night:

* CBS’ line-up of drama repeats won every hour in total viewers, while ABC came away with the overall demo win.

* ABC’s Shark Tank dove into its third season with a time slot-winning 1.7 rating and a second place-worthy 6.2 million viewers, which is a series high.

* At 9 ‘clock, the season premiere of ABC’s What Would You Do? trailed only Grimm in the demo (with a 1.6) while placing third in total viewers (5.8 mil).
