Erase his memories and seeks out the smartest person she knows for help.

"[Obliviate.]" she murmured and after a moment's worth of consideration, Harry gave her wand a half-corkscrew movement through the air to incant: "[Mobilicorpus.]"

Uncle Vernon's pudgy body lifted itself up off of the ground and settled around Harry's chest height. With another flick, his body floated after her as she walked towards the Master Bedroom. Harry rolled her eyes when she found that the door was locked, as she suspected every other door other than her own was. Even now, her relatives didn't trust her with any part of the house, despite the fact that she was helping to move them back in as an apology for being forced to move out in the first place.

"...Then again. Maybe that's why they're still not too fond of me." Harry murmured to herself with a guilty realization. "Still," She tapped her wand against the handle and non-verbally cast the Unlocking Charm. "Aunt Petunia had to have known that this wouldn't have kept me out. S'not like I got the Trace on me anymore."

Sighing at the actions of her distrustful relatives, Harry settled Vernon into his bed. She even did him the service of covering him with the duvet, but that was more because she kept finding her eyes drifting towards his crotch.

[Obey men.]

Harry closed her eyes and took in a deep shuddering breath before slowly exhaling it.

This body and stupid Oath were going to drive her mad.

'I should go to Hermione. She'll know what to do.'

With the Destination of her best friend's place fixed firmly in mind, a Determination to reach it and a final Deliberation to commit to the movement, Harry turned on the spot and-

Crack!

-Disapparated from Little Whinging and reappeared at the Apparition Point of Ration Alley.

It was a section off of Diagon Alley meant for the poorer wizards and witches. Such people were more often than not muggleborns and which Hermione, despite easily qualifying for more expensive districts, chose the more impoverished location as a show of solidarity.

"Ye' lost, girly? Ol' Frank here can show you some place to stay that's cheap. Reckon' ya' don't have a single Knut on ya' if yer' forced ta' wear rags like them."

From the way Harry was immediately accosted by a corpulent wizard in raggedy robes himself, she had to wonder if Hermione had chosen the safest neighbourhood to live in, despite knowing that she was a perfectly capable witch.

"No, thank you." said Harry coolly, wanting to immediately brush past the man before he said anything that her Oath would interpret as a command.
