Oh, I thought that was already decided on as a good thing?
I like doing it as a token of good faith and to try to protect him/them, but another part of me thinks it's wasting another message we could have sent them the key that they may or may not have.
I like both options, so I don't think I'm much help here honestly, but I appreciate you asking.
Edit: Can you tell having to wait twelve hours between sending and receiving anything is wearing on my patience a little? Or maybe it's just the rush to help them before they're all gone.
