On the train.
"So... Luna you ready?" Harriet asks
"I think you may have corrupted me." Luna says
"It's fine it's just a bit of pranking." Harriet says
"Did I hear what I think I heard Georgie?" A red headed twin asks peaking his head into the door says
"Oh I think we did Freddie." George said or was it Fred.
"So which one is Fred and which one is George? I'm 90% sure you flipped it." Harriet says
"I think they did too." Luna says looking over the paper for the ultimate prank.
"They have promise." Fred says
"That they do." George says
"Let me take a looksie." Fred says grabbing the paper before laughing.
"Is it really that good dear brother of mine?" George asks
"That it is." Fred says
"Wanna help us?" Harriet asks
"Yeah but you need to tell us about the polyjuice smoke bombs." Fred says
"It's momma Weiss's recipe I mixed I just added dumbledore's hair." Harriet says
Luna giggles at that.
"Your mom helps you with pranking?" Fred asks amazed
"No only a few of them do. Something about being the inheritor of the marauders. Although my dad love potioned my mom, and another one was a death eater. But we don't talk about that, oh my brother is also the number one knuckle head ninja." Harriet says
"That's why she said that last year!" George shouts
Harriet smiles.
"Yep, momma Lily helped them make the map." Harriet says as she pulls out her copy of the map.
"Uncle Sirius was padfoot." Susan says having snuck up behind them.
"Yep and Remus Lupin was Moony then my "dad" was prongs and finally worm tail the betrayer." Harriet says
"So do you know how they got their nicknames?" Fred asks
"Of course it's from their animagus form." Harriet says and Luna nods since she would listen to Lily's stories with Harriet.
"So, what's this about pranking?" Susan asks since Sirius kinda got Susan into a prank war with him over the summer.
"It's this." Harriet says holding what appeared to be a smoke grenade filled with polyjuice potion.
"What other tricks do you have?" Fred asks
"I have gender change fluid." Harriet says
"Fair warning don't prank Professor Kyra, according to momma Lily she could make a marauder cry." Luna says
"Momma Lily Luna?" Harriet asks
Luna nods.
"She told me to call her that." Luna says
"Why is that?" George asks
"Momma Kyra pranked the god of pranks a few times..." Harriet says
"Masks ready?" Harriet asks as she opens up her trunks to show some old fashioned gas masks.
"We aren't pranking ourselves too?" Fred asks
"I don't want to walk around as a wrinkly old man for a few hours." Harriet says with a shiver as she puts her mask on.
Susan and Luna scramble to do the same.
The twins seem to move a light speed once Harriet pulls the pin on the grenade and throws it into the air vent quickly blocking it off with a rubber tray.
"Where did you get that?" Fred asks muffled through the mask.
"I just had it." Harriet says as the screaming and yelling starts.
=====================
Meanwhile Kyra is sitting in the prefects cart instructing them on how to cast a bubble head charm.
"So, any clue what just happened?" Kyra asks since their meeting was interrupted.
"I will go and check." a senior Slytherin prefect says leaving.
Meanwhile Kyra has to suppress the urge to laugh.
Poor Hagrid they should be arriving at hogwarts in 20 minutes the half giant is going to be so confused.
