Hazbin Hotel/Harry Potter : Ava goes to Hogwarts!!

First task

Ava couldn't help but look around in excitement. She had never been in a castle before. Well she's never been to a castle on earth before. Although where would she even find a castle in New Orleans? Not to mention the United States is not exactly known for its castles. Clearly, it must be a European thing.
She couldn't help but wonder if this was similar to her uncle Lucifer's castle. That castle could be compared to a ring leader's circus tent despite its extravagance. Ava especially likes the room filled with rubber ducks, so much focus on a presumably simple animal. She was curious to see what it looked like,  Ava was walking around the common room.

Harry nervously looked around the room, thankfully it was empty. He had made sure everyone was gone before bringing the pair to the Gryffindor common room. Right now everyone is in the dining hall eating lunch so sneaking her in wasn't much of a problem. He did place her under the invisibility cloak just in case, he did not want to deal with the inevitable problems Ava might attract.

Ava and Orion looked around the room. It was so red and gold. It was just like her Uncle Lucifer's minus the apple themed decor. Ava could tell Orion was getting restless. His movements were getting more frustrated as he checked every corner of the common room.

"Harry, can we have something to eat please?"

Harry flinched slightly. He should have expected that eventually everyone needs to eat at some point. "Oh um...okay." What did demons even eat?

Ava tilted her head when he looked around the room. She couldn't help but notice his sudden unease. "Is something wrong?"

"I've never really been around a demon before. I'm not sure what I can get you." Harry admitted.

"Anything really. We just want something to eat. Orion wants something too. Right?" She looked down at the plush in her arms.

The deer nodded vigorously.
"See."

Harry was still unsure. He could have sworn he read somewhere that demons can only eat meat. Or worse human flesh. Human flesh is not something that can be obtained legally or even something he wants any part of. "Are you sure? I don't want to upset your parents."

Ava rolled her eyes. "I already told you my daddy and uncle will be happy that I'm helping you. Just give me something. Please. I'm hungry."

Orion nodded along.

"Okay. Okay. Um..." Harry knew he couldn't take the two to the great hall. Everyone will notice the sudden appearance of a girl and a deer, even if they are under an invisibility cloak. He is sure Dumbledore would at least notice, the headmaster seems to know a lot of things.

An idea sprung into his head. Harry remembered the kitchen, the Weasley twins were always bringing back treats when they snuck past curfew. When considering the frequency of the treats, the house elves seem mighty agreeable. The only downside is the location being near the Hufflepuff dorms. So there's a chance that one of them could spot him.
But what other choice did he have? Picking up the invisibility cloak beside him he intended to drape it over the little deer demon only to find her and the stuffed deer missing. Panicked, he turned his head around the room hoping for any sign of the demon but he couldn't find her anywhere. Then Harry felt something tug on his sleeve. Looking down his eyes widened as Ava and Orion reappeared from out of thin air.

"How did you-"

"Uncle Luci taught me. It's how I sneak into the kitchens at night. I'm not supposed to but sometimes I'm still hungry after dinner." She pouted, Harry might even comment that it was her attempt at playing innocent.

"Oh..." Harry didn't know what else to say. "Well um...if you're okay with it we need to go down to the kitchens. That's where we're going to eat."

Ava smiled and nodded. "Okay."
