Ai and Tabby

They live in Trailer #3. They were both nurses in a MASH unit and when they met it was instant soulmates. They aren't a couple, although the creeps in #4 thought they were. They are just the very closest and dearest of friends, two halves of the same whole. They have limited telepathy with each other, but no one else, and can't stand to be away from each other.
