Gotham, Season 4

The Dentist:
You're Don Falcone's daughter. He killed my brother. [revs dentist's drill] I'm going to enjoy this.

Sofia Falcone:
It's true, he killed your brother - but not your wife, Elaine, or your son, Joseph. No, they're still alive, and probably having lunch in your two-bedroom on Seventh Ave. Right now. [he stops the drill] See, I made it a point to learn about every detail of Penguin's organization. For instance, I learned that he only trusts one man for this type of job - you. And in the event that I am ever tortured, my people have instructions to kill your family.

The Dentist:
Interesting threat, but no one's going to know you were tortured because no one is going to find your body.

Sofia Falcone:
[laughs] Oh, because you don't think I have spies in Penguin's organization. He's right about me, though; I have been conspiring against him for months, turning his captains against him one by one, and today is the day that I will finally take him down. So, if my people don't hear from me soon, your family's dead. But if you don't believe me, drill away.

The Dentist:
[to Penguin's thug] Excuse me. Her restraints need tightening.

[Penguin's thug goes to tighten her restraints, and the Dentist jams the drill into his neck, killing him]

Sofia Falcone:
A wise decision. Now untie me.
