Michael: It's dangerous, is what it is. Vicky could find out, and then the... you know, the plan, the whole plan... It's bad for the plan, Janet. That... that's the reason.
Janet: I don't understand. Given the situation, it's far safer to initiate the self-destruct.
Michael: Okay, look, see, here... here's the reason. See, I promised the four humans that we would escape to the Good Place once and for all. And without you, we stand zero chance of ever making it there.
Janet: The new Janet will be able to help you with that.
Michael: Well, all right, but it's not only that, though. See, it's also because of, um... What if Vicky found out?
Janet: You already asked me that. Why are you making such a big deal about turning me into a marble forever?
Michael: Because of reasons. There are reasons. They exist, and I just don't want to explain them right now.
Janet: What are the reasons?
Michael: They're reasons, Janet!
Janet: Okay, but what are they?
Michael: The reason is... friends. You're my friend, Janet. That's why I can't kill you. We have been through so much together. I mean, yeah, sure, for you, you know, each time I rebooted you, you met me all over again. But for me, our... our relationship has become important. You're my oldest, my truest, my most loyal friend.
I can't just get rid of you and replace you with some other Janet I don't even know. [paperclip clatters]
