Fast National ratings for Tuesday, December 2, 2014.

The CW got huge numbers for the first part of the week's "Flash"/"Arrow" crossover event, but it was "The Voice" leading NBC to victory among young viewers and an procedural repeats leading CBS to an overall win.

For "The Flash," it was the biggest audience since the season's second episode and tied for its best 18-49 demo number since that second episode.

ABC was second for the night in the key demo as "Toy Story That Time Forgot" and "A Charlie Brown Christmas" took "Marvel's Agents of S.H.I.E.L.D." to its best numbers in months. Of course, "S.H.I.E.L.D." was also boosted by not having to face a new "NCIS: New Orleans," but no matter the cause the Marvel drama hit its best figures since the season premiere in September.

Also benefitting from the absence of "NCIS: New Orleans" were FOX's "New Girl" and NBC's "Marry Me" and "About a Boy," all up week-to-week.
