What is up with this guy on the show Bones..

the one with the backwards hat. If you ask me, that's certainly out of character for a scientist to come to the lab wearing a hat let alone stupidly wearing it backwards defeating the initial purpose of a hat but even wearing it inside defeats that purpose. So why is this guy even on the show? In the past they have had presentable, intelligent assistants for Dr. Brennan. Everything this guy says is common elementary anatomy and anthropology knowledge that anyone could see had they had those x-rays and bones up close. And apparently in this recent episode its revealed he has a JUVIE RECORD? When did Dr. Brennan start hiring junkie, delinquent morons to work for her? Has she gone nuts?
