Think twice before you enter the situation, because you will draw the agression of two people towards yourself. Also remember that although the highest aim of aikido is to disable the agressor without causing harm, your prime responisbility is to protect yourself. And if this means causing harm to the agressor(s) so be it. I would say it takes a lot of guts and self confidence in your technique to step in. Sometimes it will be enough to shout (ki-ai) letting them know that another person is aware and incoming, other times you might end up on the floor bleeding...
