Gryffindors and Slytherins mixing without issues. Things have definitely changed or maybe they just grew up.
I'm confused whether Padma or Pansy are both at the party. In this part, I'm not sure who's sitting on the couch with Draco and Harry.

"Is everyone at this party part of a pair?" Padma came by and flopped next to Draco on the sofa. Draco shifted towards Harry to make more room for her and Harry loved the feeling of being pressed so closely to him.
Harry looked at Parkinson and then followed her gaze to where she'd been glaring. In the corner, darkened by the shadow of the Christmas tree, were Charlie and Neville, snogging. Harry laughed to himself because not a lot of people saw the pair in a relaxed setting because if they were out together, Charlie was almost always all over Neville.
