A former medical examiner's wife is murdered at a seedy motel, and a shocking discovery is made regarding white powder recovered at the scene. The case is personal for the team because the victim's husband was once a well-liked colleague who worked closely with Sid. Meanwhile, Stella sets a trap to capture her nemesis, Sebastian Diakos. Ashlee Simpson-Wentz and Pete Wentz guest star.

One of the lead characters of this show will be killed off in the season finale. I figure Mac, Stella, Danny and Lindsay are probably safe. So, I think Hawkes is the main candidate. Don't think they will kill Flack since the chicks love Eddie Cahill.

Man, I really hope it isn't Hawkes. If someone has to go, then I'd prefer it be Danny. I don't dislike him, but I like the other characters more.

I'm thinking it might in fact be Stella or the female detective who helped her (Is she considered a "major character?").
