[Gobbet stares hard at Tim. She has no concept of how uncomfortable it must be.]

If you didn't make it, if you just - what, were born with it? Then you're not the source. Curses are put upon things - people, in your case. You've gone all this time thinking you're the thing that needs to be destroyed, haven't you?

[She holds up a hand. Don't bother answering, she's getting the picture finally.]

Whatever cursed you, be it at birth or years later or whatever the case may be, will just curse something else if you're gone. That's how curses and curse-casters work. They kind of latch onto something and that something becomes a cursed object, but the cursed object can only spread the curse that was created for it. Until the one who did the actual cursing is gone, nothing is resolved.

[If she's being honest with herself, she's hoping this will be the end of Tim's guilt. Part of her believes that if he can take all that information in and to heart, he'll be just a tiny bit closer to wanting to live his life. Part of her knows how incredibly unlikely that is. But...she has to try, right? She has to explain what she knows in the hopes that he'll gain something from it.]

[It's sunk cost fallacy if nothing else.]
