TV ratings are on for Monday, October 13th, though The CW’s preliminary numbers were affected by football overrun and thus not usable.  Here’s a brief rundown:

• NBC’s The Blacklist was up 8% from last week’s 2.6 rating, hitting a 2.8 rating in the 18-49 demo and scoring 9.83 million viewers.
• Over on Fox, an Arkham Asylum-infused episode of Gotham (read Dave’s recap here) notched a 2.4 rating and scored 6.24 million viewers, which is down 4% from last week’s 2.5 rating.  Sleepy Hollow was even with a 1.7 rating and 4.84 million viewers.
• CBS’ The Big Bang Theory was up 2% with a 4.6 rating and 15.63 million viewers, though the numbers may be slightly inflated due to a preemption in San Francisco.  Scorpion was down 4% to a 2.4 rating and 11.47 million viewers, and NCIS: Los Angeles matched last week’s series low 1.6 rating and scored 9.09 million viewers.
• ABC’s Castle was even with last week’s 2.0 rating and scored 9.30 million viewers.
