Fully endorse the logical breakdown above.
But!! I just had to say that this prompt makes me so mad. It's more of the victim-blaming bullshit and double-standards for men and women. Medea arguably goes too far at the end, but that doesn't retroactively invalidate her. I, frankly, can't see how she communicates poorly at all. She hears what people like Jason and the chorus are saying, but just disagrees with him. And well she should, because Jason is gaslighting all over the place and trying to deflect blame - she refuses to let him get away with most of his bullshit, and brings the conversation back. He's lying through his self-indignant little teeth about being a selfish, insecure man-baby, and the only way anyone could communicate "effectively" with him would be to say, "Yes, yes, you're right, of course, I'll go, you're right, yes, yes." That's the only response he (or Creon) will accept. Seriously, though: how is she supposed to "communicate" better without just backing entirely down and invalidating herself for them?
In the meantime, she manages to buy an extra day from Creon, access to Glauce from Jason, *and* no-questions-asked sanctuary when she flees. I'd say that's pretty bloody good communication.
