BONES（ボーンズ）-骨は語る- - Episode 4.09 - Press Release 

ah no i hated clark edison! he's so stupid!
dont like the idea of jared booth.
was he ever actually mentioned before this??

yes, once (?) when Booth talked to a kid whose brother died. He talked something about his scar that he got when he was playing with his brother Jared.

Yeah I remember that, but at the time I wasn't sure whether Booth was just lying to the kid so he'd talk.

I really don't like the idea of Brennan & Jared though, it's kinda creepy or wrong somehow. Like incest or something lol.
