Hermione and Ron are on their way to Gringotts, the bank of the wizarding world, to destroy one of the Horcruxes. Ron and Hermione took a potion, so they would look like Bellatrix and another wizard. Harry and Griphook are hiding underneath the Ivisibility cloak as a man walks up to them
Well here I am Travers, now get out of the way.
Madam Lestrange, I didn't expect to see you here.
Hermione accidentilly screamed at another Death Eater
Hermione, he's another Death Eater, you have to respect him.
I'm sorry Travis, I have to go to Gringotts to check my vault. Goodbye.
Is everything alright?
Hermione shouted at the goblin, because she pretended to be Bellatrix, and Bellatrix wasn't the nicest lady.
Off course, maam. One of our workers will be with you shortly.
Let me into my vault, goblin.
May I see your wand?
IMPERIO!
Harry set a spell on the goblin, so it wouldn't notice that Hermione has Bellatrix's wand. They would know something's wrong because they stole it from Bellatrix.
Follow me.
They arrive and Harry and Griphook get out from beneath the Invisibility cloak.
Klink, Klang, King, Klang
Don't worry, it is trained to listen to the keys. Make noise with them and it won't attack us.
A DRAGON!
We have to start searching for the cup. After we found it I'll get the sword, right?
He'll never get the sword.
Off course.
Imperio! Stay here and help us!
I know he won't give me the sword, I'll just take it when the time is right.
