In the past you would have left the kitchen when things got this heated, but Jupiter in Cancer has made you intrepid. Not only do you know that you're more competent than a supervisor, but you can already see how this person is on the way out. All you have to do is wait. Mars may be the planet of frontal assault, but Jupiter is laid-back. That's because Jupiter knows it can pull rank if need be, but it's always better if the other party comes to that realization themselves so that they yield the field without you ever having to get your hands dirty.
