When she noticed the person who was her student, Sera was admittedly a bit surprised and amused. It was the Hogwarts Potions master, Bruce Banner. It looked like even professors wanted to learn something new now and again. Of course she wouldn't have pegged him for a dancer, but that was probably why he was here and taking lessons.
Hearing her name, she offered a friendly smile and nodded. "I do during the summer in exchange for studio time." She said as she motioned to the near empty area. Once lessons were completed, she would have the place to herself to practice. "Though I'm surprised to see you here sir. It looks like our roles will be reversed for a time." The smile that crossed her lips was playful as she stood straight before dipping into a graceful bow. "I am you instructor, Miss Vetrov. You will call me that while in the studio please and I will be calling you Bruce." Because she could. "Now tell me, have you ever danced before?"
