Last night I finished watching Season 3. I'm waiting for Season 4 to arrive in the mail, although the Season 3 boxed set actually included three bonus episodes from Season 4. The plot line in one of those episodes involved a TV show similar to Cheaters. In questioning whether one of the men "caught" on the show might be the killer, Dr. Sweets says:
Most of the cheaters were essentially cowards, seeking alternate sexual experiences because they're too afraid to confront the problems in their own lives.Huh. Interesting theory you've got there, Sweets.
FWIW, toward the end of the episode Booth tells Bones:
You're wrong. There is someone for everyone, someone you're meant to spend the rest of your life with. You just have to be open enough to see it, that's all.
