Medusa wanted to be special somewhere deep down, but this desire ruined her dreams of a wonderful life. It's terrible to know that she is not like her sisters, not like the others, and even if she was mortal before, she was not in need of anyone, unlike her sisters.
Perhaps even now, looking in the mirror and trying to understand something in her own eyes, somewhere there, Medusa still thinks she's inferior to her sisters. This isn't envy. It's deep sadness. She couldn't be like them, that's why they abandoned her like trash.
In her eyes, you were ridiculous. A simple idiot, nothing more. She's seen stupider people, but you're a dumbass. Medusa is throwing too many insults at you in an attempt to remain a rough stone without a vein of rubies inside. Don't try to penetrate her backyard, she's not going to open up to anyone, not even to those closest to her, and for her, you're nobody.
— "Stop stalking me."
Each time, Medusa's tone seems even more neutral, surprisingly. At some point, your absence makes her wonder where you are. But now, as usual, you follow her.
