Sabryna hadn't really waited for a reply, making the decision to go to the Room of Requirement whether she was wanted or not. But she brought her journal with her, just in case she got an no along the way. She could always turn around and go back, right?
She was wandering along, one hand wrapped behind her back and gazing around her when she spotted Tristan. She practically skipped over to him, figuring that this was the spot.
"I didn't tell any prefects," she assured him as she approached. "And I swear to be good and not talk too much and let other people get a chance to talk or you can put a silencing charm on me, but I don't want to miss out on the fun!" she said, then quickly bit down on her thumb to silence herself. She smiled somewhat sheepishly. "Can I come in and play? Please?" she murmured around the digit.
