"The Flash" has been a hit since it debuted on The CW, regularly landing at the top of the network's charts. The latest episode, however, took the show into new territory, tying with a repeat of CBS's "NCIS" the #1 slot for 8PM.
The return of Reverse-Flash helped fuel the DC Comics-inspired show to an audience of 3.67 million, an 8% increase over the previous week's mid-season debut.
"Marvel's Agent Carter," meanwhile, maintained its ratings from last week's 2-hour debut (0.9/3). While the ABC show's Season 2 premiere was lower than its Season 1 finale, when the Live+3 numbers were factored in, the premiere saw a 44% increase to a 1.3 rating.
The CW, which followed "Flash" with a repeat of last week's "DC's Legends of Tomorrow" debut, was the third place network overall in viewers aged 18-49 for the evening.
