DEFINITION Double Mirror is a double stance for fictionfolk who's reaction to finding a double "mirrors" the double they meet's reaction (ie. A is a double mirror, and meets B, who is a double of A and doesn't like doubles, so A feels repulsed by B. A then meets another double, C, who gets excited by doubles, so A gets excited in kind.)
Feel free to put on Wikis or give me ideas to make the phrasing less clunky
