Not right now. Right after I post this, I'll post in the RP about me working on that tool for you. Don't expect me to be like everyone else and go to the Thundering Falls just because I feel like it. No, I'm going to be realistic and stay at the cave.
Perhaps what you can do is remember that I had promised in the morning to give you something that would help you catch fish more easily. (Yes, that is exactly what I had said) If it is close to dinner time, then you could come back to the cave, where you know we are likely to be. I'll probably be finished with that tool by the time you arrive. After giving you that tool, then we can start that plan by you asking Ruby to speak with you in private.
