Chapter 11: One Mistake is All it Takes

So usual backround info on this chapter: Hermione, Harry and Ron planned out a brilliant idea of using Polyjuice potion in the 7th movie so that they can look like Bellatrix Lestrange and get into her volt to search it for a Horcrux. But 1 tiny mistake alerts the Goblins. This is about how very easily this mistake could have been avoided.

"Hermione, I'm tired, we have a big day tomorrow, can't we just go to sleep" Ron said sleepily.

It was 11:30 the night before their trip to Diagon Alley. Only Hermione, Ron, Harry and Griphook were awake in Shell Cottage.

"I just have a feeling that we are missing something, please can we review the plan one last time" Hermione said looking at Ron.

Ron yawned "Make it quick"

Hermione took out a suitcase and layed out a blue print of Gringotts, she began.

"In the morning I take the Polyjuice potion and I transform Ron" Hermione started.

"We have enough of Bellatrix's hair to transform right?" Harry asked.

"Yep. So then Griphook rides on Harry's shoulder and they put the invisibility cloak on" Hermione continued.

"have you checked if there are any movement sensors at Gringotts?" Griphook asked.

"Yes I checked, there aren't. Anyway we walk into the bank and go up to the goblin in the furthest part of the room" she used little rocks to trace their path in the blueprint.

"So then if they ask for the key I'll say I never needed the key before and I'll just give them the code to the vault which is 6739- hopefully they won't want more information" Hermione said biting her lower lip in anguish.

"What if they are alerted that someone may try to break in and ask you further questions?" Harry asked instantly noticing the worry on her face.

"Well then we will either leave in peace and try later as someone else or I might be able to answer their questions-" Hermione paused, clearly realising something for the very first time.

"I can't bring my wand" Hermione said something clearly in her mind.

"WWHHHATT?" Ron asked.

"I can't bring Bellatrix's wand" Hermione repeated slower.

"Why?" Harry asked his eyes confused.

"Don't you see Harry? If they are alerted that the previous day Bellatrix lost her wand and then we walk in and I have the wand, won't that look terribly suspicious?" Hermione asked trying eagerly to get Harry to understand.

"OOOOOH" Harry said realising the fault in their plans.

"But you need to bring a wand just incase some death eater's start a fight!" Ron said.

Hermione looked in thought for a while,

"What if Harry brings an extra wand" she said slowly,

"That way if I fight starts, Harry just throws me the wand?" Hermione said following her thought.

"That could work" Harry said thinking over the plan.

Ron suddenly let out a loud chortle and snort.

"What?" Hermione demanded.

"Well don't take this personally but you are not the best at catching" Ron said laughing and nudging Harry in the Ribs.

Both Hermione and Harry stared at Ron in dagger eyes, waiting for the laughing to stop. The smile on Ron's face disappeared as he saw their grim expressions.

"KK fine, I'm sorry, I'm sorry" He said.

They rolled their eyes.
