Your question indicates that there are multiple miscreants embroiled in varying degrees of misbehavior. My advice is to find the one that you think is the least culpable (or perhaps the most amusingly culpable), and build a case for why that person ought to bear the bulk of the guilt in the story. If you’re really good at BSing, try making the case that nobody is guilty of anything. For added challenge, do it without resorting to relativism.
Do it right, and your teacher will heap laud upon your humility’s back so that it breaks.
There are ways of sculpting a homework question so that its odor does not offend @jeruba’s delicate nose. Like not mentioning that it’s a play, or that it’s by Edmond Rostand. In this way, you will more likely come across as someone who knows the material and is looking for others who also enjoy Rostand’s work.
