The second episode of “Downton Abbey” was a shocker: Anna was raped, a situation that caused a scandal in Britain when the show aired this fall. But that didn’t deter viewers. “Downton” was up 22% over last season’s second episode. The Crawleys scored 7.94 million viewers. Their household rating was a very healthy 4.7. This means that the PBS Masterpiece drama finished third in narrative TV to “The Good Wife” and “The Mentalist.” ABC and NBC would love to have the “Downton” numbers. Bravo!
