When the third guy with them got shot, I thought maybe it was just two murders/near-murders going on in the story, totally unrelated. I was pretty sure Jamie wasn't just going to be in the one scene (his first when he and the other guy were called in to talk about the turtle and the armadillo and the toys LOL), but not 100% what his character's involvement was.
Not knowing much about the the show (I know it sounds ridiculously silly, but I don't watch that many US procedurals, esp the hi-tech ones), I had no idea. It was really ridiculous in the end, esp because of the whole girl sleeping in the parents' trailer w/out being noticed part.
But it was pretty funny that it was Jamie in the kitchen with a golf club.
