Dr. Oliver Cox: We also have a DNA match between hair on the head of this body and the Disco Strangler.
Sergeant Jeffords: Sir, this is clearly Zumowski. And that's a good thing. You can finally say good-bye to your nemesis.
Captain Holt: Thanks, sergeant. That's a nice thought. For an idiot to have. Look at this.
Charles: A dirty little string?
Captain Holt: Oh, it's not just any old string. It's a yo-yo string, the most dangerous part of the yo-yo. The Strangler wanted me to find this. He's out there, and he's taunting me.
