Hirigami: "Ugh... Can you stop whatever you've been doing?"
*mouths the words 'answer him' to Piper*

Technically he is... damn never though about it

Yeah. Y'know Hirigami is mainly vegetarian, aside from salmon.
Hirigami: "Be quiet."
Aand now Piper has to annoy him again.

Piper: "I've never been able to read on lips. But... uh... sure. I can stop"
Will: "But i suggest you don't touch his pizza anyway. I'm kinda stuck to a wall here"

*sigh*Piper, please annoy Hirigami as much as possible.
Hirigami: "Why are you telling her to annoy me though?"
...
Hirigami: "Agh, no, I can't keep doing this, someone let me out of here please!"
Oh no! Don't annoy him! He'll go kinda sorta evily if you do right now.

I just found the cutest fanart of Percy and Nico.
Will, Annabeth and Percy: "Let me see!"
Nico: "I'll send you to Tartarus if you show anyone"

I don't care Nico. I'm a monster and therefore i like it in Tartarus. Here it is!: https://images.app.goo.gl/KKexvSx5NXbB9Qxz6
Will: "Just adorable"
Nico: "I'll murder your mother, you stupid rabbit"

Hirigami: "Argh, someone! Listen to me!"
Oh boy, I think he's going out of control, Piper, maybe you should use your power on him now?

Piper: "Okay... Hirigami, aren't you tired? You should go to bed and take a nap" *using her power*

Hirigami: "Uhh... yeah"*yawn*
Phew, I'm glad that's been sorted out. Even if Hirigami didn't use his power on Piper sucessfully.....

Piper: "I'm still confused on what power he has"
Percy: "Hey, where's Aria? Does she like pizza with fish?"

Aria left earlier and she likes sweet and dry fruits or berries, not meat. Also Hirigami has a mind manipulation ability.

Leo: "So he's like Piper then?"
Piper: "I didn't even notice that he started using it"
Percy: "I also have that. But only with sea creatures. And it's more like i can speak to them telepathically. Not manipulate them"
Annabeth: "He has only manipulated one person in his lifetime. By accident. He's not smart enough to do it on purpose"

Percy: "Bob isn't something to joke about, Annabeth! He's trapped inside Tartarus forever now and will never get out!"

He didn't activate it properly on anyone here, Piper.
Aria: *Aqua Jets back*"MagoChestoPiiieeeee!??"

Piper: "Oh. Okay"
Percy: *cries*
Annabeth: "We should leave"
Percy and Annabeth: *leaves*

Wha? Why was he crying? What wha...?
Aria: "Magochestopiiiiiiiieeeeeeeeee!"

Bob was a titan that Percy accidentally gave an amnesia and then basically accidentally manipulated him to be his friend and help him when he needed him. He sacrificed himself to save Annabeth and Percy from Tartarus

Ah. I think I get it.
Aria: "Maaaaaagooooooooooooo Cheeeeestoooooooooooo Piiiiii-"
*cavors Aria's mouth*Stop, please just stop.

Percy: *stops crying* "Did i hear Aria!?"
Annabeth: "Uh... no you didn't. That was only your imagination"
Percy: "Don't lie to me! I heard her!"
Piper: "No you didn't. You miss your little sister and wants to hang out with her right now" *uses her power*
Percy: "...Okay" *leaves with Annabeth*
Annabeth: *whispers* "Thank you"
