So, I thought of a thing for your Hannah Hook AU?

"Right!" Harriet glared at those assembled, finishing up her ten-minute-long speech, not that any of them had counted or anything. "Do you have anything to say for yourselves?"

CJ raised a hand. Harriet ignored her.

"You're all grounded," the eldest Hook finished.

This, of course, met with an immediate outburst of protest.

"We're what?" CJ demanded.

"You can't do that?" Harry yelped.

"But I didn't even do anything!" Hannah objected.

"Grounded, Calista, and I most certainly can, Harry, and that's exactly it, Hannah - you didn't communicate with any of us for months, until one day you end up fighting on the side opposing your siblings - what were we supposed to think?"

"What? That's totally unfair!" Hannah argued. "They started it! Besides-" She gestured wildly, seeking any deserving target, and finally pointed at Ginny, who was standing the closest to her and had so far been watching quietly, not saying anything. "-She's the one who almost got me killed by crocodiles!"

"I said I was sorry!" Ginny finally broke her silence to say. Turning to Harriet, she asked "Does this also apply to me too?"

"Yes," Harriet said.

"But I'm older than you, and I'm not even-"

"I don't care!" Harriet clapped her hands once, sharply. "All of you are grounded! Starting now!"

And this is one of the many reasons why Hannah runs off to create her own circus at 15 with Haul, Amira, and her crew. And why she isn't seen for 7 years afterwards lol.

I wonder how they didn't find her though when her crew was literally called the frickin 'Storm Bringer's circus' and is always near a boat?
