The OP sounds more like sheer vindictiveness and spite. Chalk it up to experience. If there is one thing your AC should learn is to address blue a bit more respectfully in the future. There is no reason for him to "Go Nuts" and start the cascade. Blue may not have started out hating your guts, but it sounds like you gave him ample reason to after the outburst. You can't control what other people do, but you can control how you handle the situation, and teach your team to do the same.
