"The Girl in the Gator" is episode thirteen of season two of Bones, the forensic drama series based on the books by Kathy Reichs.
I Hate Clowns
This episode opens with Booth and Brennan exiting the diner. Booth is getting a phone call about something in Florida. Booth is having problems hearing due to an ice cream van playing loud music. The van keeps following them and the driver keeps the music playing. So Booth pulls out his gun and shoots the clown-head loudspeaker to shut it up. Although this works, this tends to be considered to be an overreaction. Even if you don't like clowns.
Shoot the Alligator
Consequently, Brennan heads down to the Everglades without Booth. The latter has to see the department shrink before they will let him have his gun back. Brennan is therefore going to be working with someone different, an Agent Sullivan. At the scene, the local ranger has had to shoot an alligator, called Eugene. He's not happy about that, but he spotted the gator eating a human arm when the ranger shooed off some spring breakers. Brennan quickly starts clashing with 'Sully' when she wants to ship the entire alligator back to the Jeffersonian. She does find a locket in its mouth though. The area is also going to be dragged for other body parts, as gators eat matured meat.
A Strange Source of Music
Back at the lab, the gator is found to be playing music, as there's a rugby-ball shaped music device inside it. As well as a human foot. Booth is going to see the psychiatrist (played by Stephen Fry). He wants the shrink to simply sign his paper saying that he isn't crazy. Of course, it isn't going to be that easy - especially when Booth says that he shot a clown-shaped speaker on an ice cream truck because it was irritating him. Booth is finding the shrink to be very, very English. You can see that Booth is going to find it very irritating - but he's going to have to do it, or he won't be allowed to get back to work. It's probably going to involve the death of Howard Epps in the previous episode, "The Man in the Cell". Booth also ends up building a barbecue.
Brennan quickly identifies the body, that of a girl missing for three weeks. Sully doesn't seem to be winning Brennan over yet. So far, the cause of death is alligator. Which would make it a really short episode, if true. So it won't be. The girl who was with the dead girl doesn't remember much of the night that she went missing. The dead girl appears to have been raped, stabbed and also associated with a website that pays drunk college girls to take their clothes off (or more; looks to be based on an actual site as well). The man running the site, despite being a bit of a creep, is too obvious to be the person who did it. There is also a preacher who is trying to save the souls of the girls but the creep, Monte, treats him quite well. The girl is also linked to a bouncer, but there is definitely more to it than that.
Brennan isn't sure what to make of Sully, who seems to have a whole bunch of skills and interests.
