Those lines are so powerful because there are two versions of Medusa myth. One when she is sexually abused by Poseidon and then the other when is a consensual relationship. The episode don’t clarify which version is it (although it is hinted to be the kids friendly one) but it also doesn’t matter.
In both versions she is still the victim. In the first one because Poseidon harmed her, yet Athena blamed the victim. Medusa says how she lived to make Athena happy. And then she gets betrayed by the person she loved the most. A betrayal that still happens in the second version. Athena saw how Medusa love wasn’t just for her and decided to punish her for that. Even though Medusa said Athena never answered her prayers. She still expected Medusa to devote herself just for her and couldn’t bare the thought of someone else stealing that.
I just think this episode does so good in the nature of the myths. Seeing how Medusa was turned as a monster bc of Poseidon and Athena’s feud. As well as showing her bitterness and how she deals with the grief. I found this powerful since many survivors of sexual assault choose Medusa as a symbol to fight back. Hence the lines she says on the show, and how she also calls herself a survivor. Truly amazing work.
You know what would be a really interesting plot twist?
If Mizu actually did find her father and it turned out he just wasn't evil. Like, if the man, even as a foreigner, was a genuinely decent person.
It would be interesting to see the moral struggle for Mizu after her whole life's mission was to eliminate the guy. Plus, they vilify the white men so much but it would be interesting if one of them was just a man, not a colonialist horror.
After pondering on it for several days, I have officially decided I did not like the direction of KFP4 and have banished it from my brain. It is no longer canon. KFP4? What's that? Don't know what you're talking about.
