Raven & Sarah
"I hope you enjoy them," Raven said sincerely. She did want her to have a good time, but she also wanted the slight satisfaction that it was her designed fireworks the girl would enjoy. Raven was a tad selfish that way.
"As for the headphones...I built some. Some are store bought," she explained. "But Hermione cast a noise dampening spell on them. So she's the real rock star, here."
Yes, Raven could even praise others for their work as well.
