Arastoo Vaziri (Pej Vahdat) is a devout Muslim and scientist on "Bones." He was concerned that his colleagues would notice this contradiction, so he played up his Iranian heritage to make it appear as if his spirituality was more of a cultural holdover. Vaziri even pretended to have a pronounced accent as he thought that would also serve his duplicty better. He was a translator in Iraq, as well as an intern at the Baghdad museum.
"Why did you ask everyone to leave. Are we doing something shameful?"
"Dr. Brennan said to be especially nice to you when the science was difficult."
