Did all girls giggle? Her sister was forever giggling, and AJ never once did. Sure, she would laugh, but holding a hand to her mouth while giggling... NOPE. It just seemed foreign to her. A girl's question for the professor made her wonder the answer. Oh... so they were supposed to be guessing who was behind the illusion. Whoops. AJ had been about to guess who the girl was standing before her. At least she hadn't led on with that in her question so she was just going to play this off. Nothing to see here.
Now that she knew what she was to be guessing AJ's mind went back to the giggling. That was a girl thing so that meant that whoever was behind this disguise was a girl. Boys just didn't giggle. Unless... he was trying to throw her off her game because HE wanted the prize at the end of the lesson. Is that it, mister? Oh, AJ was on to you. He/she was eyed.
Outside.
"Good answer. I love the outdoors." Nuuuu. She was giving away secrets and answering questions that didn't need to be answered. Don't go giving things away, Valentine. It was her turn to answer.
"I'm in the best house ever." Okay, she couldn't leave it at that.
"Gryffindor."
But, once she had said the greatest house there really shouldn't have been any question one which one that was.
What to ask next? AJ tapped her chin as she thought about it.
"Who is your best friend?" That could be super helpful.
