I mentioned how compelling dark Piper would have been, so I have to elaborate on that. This one’s for @winnies_sketches
Piper doesn’t like using her powers at first. She rejects any connection to Aphrodite, and that includes charmspeak.
But then she uses it on some monsters to save Leo and Jason, and thinks hmm, maybe this isn’t so bad. So she starts to use her voice more and more, only on monsters. Compared to all the other powers the other demigods have, Piper feels really inferior, so she practices her charmspeak over and over to try to fit in
Then one night on Argo II, she tries it on Jason. She asks him to get her a glass of water, which he would have done anyway, but his eyes glaze over and instantly gets her a glass. She feels guilty, but can’t deny the small rush of power it gives her. She finally has a way to contribute, to fit in, to show that being a child of Aphrodite is more than people think
In this au, Piper and Jason fall into Tartarus, and that’s when we see Piper truly start to lose it.
She forces monsters to help them, to turn on their own kind. They hate her for doing it to them, and she feeds off their hate, uses it to grow stronger. And then when they come across Akhlys, she attacks and injured Jason before Piper can force her to help. Her eyes turn black and instead of just leaving, Piper tells Akhlys to stop breathing. She does, and Jason and Piper watch the goddess fall to her knees, clutching her throat. The Jason snaps to his senses and begs Piper to stop, that no one should have that power. And Piper does. But she doesn’t forget.
After Jason and Piper get out, Jason has a long conversation with her about how scared she made him feel with Akhlys. Piper explains that if she has that power, why shouldn’t she use it? It’s no different than Jason flying
And then Jason is truly alarmed. Because Piper seems like she’s too far gone. The others can’t look in her in the eye after that, they don’t know exactly what happened down there but they see her force an entire legion of venti to help one day
Piper becomes so used to her charmspeak it starts to bleed into her everyday speech. Until one day she jokingly tells Leo to go take a swim. He promptly flings himself over the railing and plummets to the ground. He’s saved just in time by Jason, but Piper is so rattled by the incident she refuses to speak for days.
And it’s Jason, again, who pulls her out of it. Who convinces her to come back, saying he trusts her with his life. He always has. She eases up on the charmspeak, only using it on monsters and only when absolutely necessary.
Then comes the fight with Gaea. She doesn’t want to kill to Gaea, she doesn’t want to give into that side again, but she has to to save everyone. So as Jason struggles to keep her aloft, she tells Gaea to stop breathing.
But her charmspeak is so powerful it washes over Jason too, and he stops breathing. They plummet fall to the ground, saved by Pegasi, but it’s too late for Jason.
And Piper, hating herself but also hating Aphrodite for giving her this gift, completely goes rouge, vowing to tear her mother and Olympus down stone by stone. She’s the enemy no one can stand against, because her will always overpowers the wills of others. With a silver tongue and frozen heart, Piper McLean becomes the enemy.
