Quote from Eleanor in The Eternal Shriek
Eleanor: Janet? Janet: [appears] Hi, there. Eleanor: Hi. So the only way out of the neighborhood is a train? Janet: That's correct. I am the only one who can call the train, and it needs me to operate. Choo-choo. [chuckles] Eleanor: One more question, and, um, this is a little weird, but can we... uh, shut you down? Janet: Yes, great question. There is a kill switch in a remote sector of the neighborhood in the event that I malfunction and attempt to harm the residents. If you press it, I will be destroyed. Anything else? Eleanor: No, that's good, thanks. Janet: Okay. [disappears] Chidi: Whoa, you want to kill Janet? Eleanor: Michael can't retire if he can't leave. He can't leave if there's no Janet to run the train. It's a perfect solution. Janet, high five, please? [Janet appears and high-fives Eleanor] Thanks, babe.
