An exorcism is performed on a girl named Amy, her father disturbs it, and Amy ends up killing both her parents. Also, a homeless guy is found dead: Sara and Ronnie the newbie do this case. We find out that Grissom's studying Colony Collapse Disorder in bee colonies, after he sticks his head up a hole in the wall, which turned out to be filled with bees.
For me, this episode was kind of average, but of course still fabulous (what CSI episode ISN'T fabulous?). Sara moves to swing and newbie Ronnie is introduced. It's true, what I read: Ronnie IS really annoying! "Do ants have tastebuds?" Storyline was well written, but this wasn't one of those super-fantastic episodes that you'll remember forever.
