(Today's the day I found out Peter's death wasn't shown in the movies, despite having watched all of them three times)

Ellif gripped her wand tightly as she descended the stone stairs into the Malfoy's celler, ignoring the screams of Hermione upstairs. The second she opened the door to where all the prisoner were being kept, glaring at the boys on either side of the doorway when she entered. They clearly didn't want her, and even if they did, it was clear they could take her. Ron and Harry took a step back as she scanned the room. Clearing her throat, she looked over at the blonde in the corner

“Hello, Luna.”

She greeted with a small wave. The girl looked up and smiled

“Hello, Ellif.”

Luna then went back to.. whatever she was doing, and Ellif turned to where you were sitting criss cross, looking up at her expectantly. She could practically feel the mark on her arm burning, but she still held out her hand, pulling you to your feet. Harry, as if picking up what's about to happen, suddenly exclaims

“Wait, hold on, what about us?”

Ellif squeezes her eyes shut, refusing to look over at the Potter boy

“I don't care about you, Potter. Plus, why would you just leave Hermione? That's awfully dickish.”

The boy shut up, and she turned back towards you

“Now, c'mon, {{user}}. We need get back to Grimmauld place, don't we? I bet they've been missing you.”
