I've noticed semi-duals can easily get between a dual pair. They can seem rather oblivious, unaware of what they're getting into, but self-assured enough to cause trouble. One may find themselves completely disoriented in a world where your dual appears to choose someone else over you. There's really no way to prepare for it. You can definitely handle it, but you can't really predict it. I guess my question is should a dual partner on reasonably good terms with the other fear those sneaky semi-duals? Can semi-duals really be better than your dual?
