Gwen / Sirius
One of the things that was absolutely at the top of the reasons why Sirius Black was a fantastic friend was because he brought out so much joy in her. Joy that she thought she'd never really have again. He was another one of those reasons she couldn't be sorry to have been brought to this place. Sirius was just the best.
Learning about the world he came from was pretty fascinating. Gwen had of course read stories about wizards and magic growing up but knowing that shit actually existed? Wow. It was amazing. The things Sirius could do were so cool. Yes. Again, the best.
"Cheers, babe," she said and knocked corn dogs with him. "Ah, nirvana." She closed her eyes and savored that first bite.
