David Boreanaz

The angles: Dr. Temperance "Bones" Brennan (Emily Deschanel)-FBI Agent Seeley Booth (David Boreanaz)-Dr. Camille Saroyan (Tamara Taylor).

The history: Bones and Booth are a classic case of opposites attracting. She’s scientific, he’s intuitive. She’s socially awkward, he’s sensitive to feelings and situations. They bicker, they insult each other, but they also care about each other — and they’re obviously in love and lust. In the show’s first season, Booth had a girlfriend, but we didn’t see her very often, and Bones had an occasional date or romantic possibility. But this season, the "Bones" writers have inserted a triangle right into the middle of the show. Upon returning from vacation, Brennan was surprised to find she was answering to a new boss at the Jeffersonian Institution: the beautiful Dr. Saroyan, a first-rate pathologist who had a romantic past with Booth — and has shown up in his bed this season.

Desired outcome: We all know Bones and Booth are a great match. As Deschanel told us last season, "These are two people who are attracted to each other, but they don’t really think they’re right for each other. ... They belong together. But it will take a long time."
