One particularly interesting question that's come up for me (well, sort of). What happens if you take one instance of a person and have them exposed to the Watts-McLeod virus while one or more instances of them remain elsewhere in the solar system. They'll develop async potential, as usual. What happens if those various branches decide to merge after a relatively short time - say, a few hours to a few days? We don't really know how merging works exactly and we certainly don't know how psi is transmitted between brains, so there probably isn't a 'canon' answer, but I'm curious as to what interesting failure (or success) modes there are. What does the person experience, do their forks go crazy, is a successful merge even possible?
