Medea: Jason please forgive me for all the things I said. […] I have been out of my mind, hysterical. […] Jason: I praise you now, Medea, and I did not blame you (150)
Medea is apparently the cleverest person in Corinth. She's easily able to manipulate Jason into believing that she's no longer mad at him, even though she's ranting and raving for days. It's sort of amazing that he falls for this so easily. The play would have a lot more dramatic tension if Medea had at least one worthy adversary.
