Dad.
I agree with you entirely. I'm hoping she dies. It's the only way to solve all this permanently, but we can't do that until we have a safe and sure way in.
Dad, if you're certain that this is how she needs to be handled, then I'm gonna be with you. One hundred percent with you. But I want you to be sure. I'd hate to see this go badly and I don't wanna lose anyone again. It's just - I know you. And sometimes you make the bad decisions with the best of intentions at heart. Hell, we all do. Sometimes it goes well, but mostly it ends up screwing.
Just promise me that if we do this, we're doing it together. All of us as a team. You're not gonna run off half-assed at the last second and make some decision that ends up getting you killed.
