Dancing with the Stars continues to be Castle's Monday night BFF. DWTS, the highest-rated show on TV, loses almost half its viewers after 10 p.m., but that still leaves more than 10 million to watch Nathan Fillion (Richard Castle) and Stana Katic (Det. Kate Beckett) on Castle. This week, ABC's Castle episode "3XK" brought in 11.8 million viewers, making it the top show from 10 to 11 p.m., over CBS' Hawaii-Five-0, which averaged about 10 million. Both shows easily beat NBC's Chase, which brought in just under 5 million viewers.
