In 'Bones' Season 10 Episode 13 titled, "The Baker in the Bits," Booth and Brennan, together with the whole team will piece together the mystery surrounding a series of ritualistic murders of four people. According to Latin Post, the team will race against time to hunt the psychopathic murderer before another victim is killed.

"When the body of an ex-con is found in pieces, the Jeffersonian team will investigate a local bakery known for employing former felons," the official synopsis of "Bones" Season 10 Episode 13 reads, Hollywood Hills quoted. "But they will soon learn that the victim was involved in a robbery gone bad, and start targeting suspects from the ex-con's past. Meanwhile, "squintern" Arastoo Vazirir (guest star Pej Vahdat) will have to decide whether to return to Iran to visit his dying brother, which will cause friction between him and Cam."

While the Jeffersonian team investigates the death of an ex-con, Ecumenical News revealed squintern Arastoo Vazirir will face the challenge of making a tough decision between risking his life for a dying brother in Iran or stay with Cam.

"He goes back because his brother is dying. That will come back in a very, very major way later on in the season," executive producer Stephen Nathan told TVGuide. "The only way he can leave is to solve a particularly sensitive murder, and of course he can't do it without help."
