"If one of us sends 23G, that means we think we might be about to vanish for reasons having nothing to do with Leah.  46G would mean that we both ended up sending you that signal independently."

"If we both vanish and there wasn't any signal... judgment call.  If I were in your shoes I'd maybe stealth it for a week and then start waking up the other townspeople, and not letting Leah know early about that, but also not assuming it was her."
