This season on Bones, when Booth returns from Afghanistan with a new love interest (played by Katheryn Winnick), Brennan experiences an emotion she’s not terribly familiar with – jealousy! “She feels something, but she doesn’t understand what’s happening,” Emily Deschanel told “She’s covered her emotions so much, and built this wall around her. I think there’s jealousy there, but she’d never admit it to anyone else and certainly she wouldn’t admit it to herself. I don’t even think she can let that happen.” Perhaps Brennan will turn the tables on Booth in November when they will reportedly go on a “cougar” cruise and some of the young men on the prowl for older women fall for Bones instead. The new season of Bones begins Sept. 23.
