From TVGuide.com: "With CSI (18.75 mil) plunging 1.25 mil from its last fresh outing, Grey's (18.76 mil) gained 800K and seems to have barely edged out the crime drama in total viewers this week (as well as the usual demos). The Office (8.4 mil, -580K) and Scrubs (6.68 mil, -350K) each slipped. Supernatural matched last week's 3.28 mil."
From Variety.com: "As for CW, "Smallville" (1.7/5 in 18-49, 4.3 million viewers overall) wasn't as strong as a year ago, but "Supernatural" (1.3/3 in 18-49, 3.3 million viewers overall) was down just a tick year-to-year."
