CSI: Crime Scene Investigation, Season 10

Ray:
A man who wears a tuxedo every day doesn't forget his bow tie.

Catherine:
So what, someone took it?

Ray:
His bow tie's missing, his intestines are tied into a bow. That can't be a conscidence. I think Dr. Jekyll took it as a souvenir.

Catherine:
A souvenir? That's what serial killers do. JoJo died of natual causes.

Ray:
I have a bad feeling that this isn't the last time we're going to see Dr. Jekyll and I think next time he's not going to be content starting with a dead body.
