In this episode of Bones, called "The Doll in the Derby," Angela goes undercover as a roller derby skater to help solve a case and Booth keeps an important secret from everyone.
Both of the main storylines in this episode were completely different from each other, and yet both were equally important. Angela going undercover was just a fun way to spend an episode and I got a kick out of seeing her on skates and doing some investigating. Although the highlight of that story of course was her getting completely snockered and then not only making out with Booth, but asking if she could make out with him some more. Totally hilarious.
