Mediation Backfire YKTTW Discussion
Everyone knows when you see two dogs tearing into each other, the last thing you should do is try to get between them. What some don't realise is that the same can be true of people, too. Two characters in the middle of a bitter argument make up their differences over a common love of abusing someone else - usually, but not always, the person who tries to get them to make up in the first place. Compare Enemy Mine, when something similar happens to mortal enemies. Subtrope of No Good Deed Goes Unpunished. Quasi-inversion of Apple of Discord, when a third party makes two allies start arguing - this is about making two arguers temporarily join forces against the intruder.
