Neville was a little bit surprised when the woman just appeared in the greenhouse with him, but not particularly startled. He was more than used to people apparating in and out around him so it wasn't that out of the ordinary. The way she showed up, with the bright showy display of sparks, was a bit more intriguing, but he didn't really question much. He was getting used to there being so many different types of magic in this place.
"Yeah." Neville answered with a little wave when she approached him. He was a little bit disheveled, and the bottom of one of his pant legs was ripped and bloodstained, but the cuts under it had already been healed. He glanced to the book and the pouch as she placed them on the table in the middle of the greenhouse and stepped up to the other side of it. "Oh! Uh, Neville. I'm Neville." He was tempted to inspect the seeds and was curious about the book but he didn't touch anything yet, "I was an herbology professor before I came here, and I studied it for a long time before that. I can't promise anything because they might be different plants than I'm used to, but I can do my best."
