The next day, the second year Gryffindors and Slytherins had their first DADA class with their new professor. They'd all heard whispers from the other classes that had had a lesson earlier on, and apparently this witch had some idea of how to teach. As usual Alexander and Hermione got their front row seats, but they were lucky they had arrived early as everyone bar a few Slytherins had aimed for a front seat.

Tonks came down from the office, and the first things that the students noticed was that her hair was now purple and she was dressed in Muggle clothing, "Good morning everyone. Hope you've had a good day already. Now, before we begin, how about you ask me some questions, if you have any. Be sure to state your name when you are chosen."

Hermione had her hand up first, and wasn't the only one, and was picked, "Hermione Granger, and I was wondering in what way you will be progressing our learning. All at the same time or allow those who are at the stage to press forward?"

"Very good question Miss Granger, and relevant as the first thing you will all be doing is an exam to assist me in pinpointing exactly where you are. Very simple, if you can't answer don't worry. Alright, how about you there."

Tonks had pointed to Lex, who rose, "Harry Potter, and I apologising for being so forward, but are you a Metamorphmagus?"

"Bravo Mr Potter, 25 points to Gryffindor. Yes, I am indeed a Metamorph, Level 5, first in my family for a while. For another 25 can you tell the rest of the class what being a Level 5 means?"

"It means that you can change anything, including sex and species, with little more than a thought. You obviously wouldn't do that until you had trained though, the internal organs of the human body are far too delicate to mess around with. Being a Metamorph is typically an inherited talent but there have been documented cases of a child being born into a completely Muggle family that has the talent. Most Metamorphmagi are recruited by the Unspeakables during their final years of schooling due to their ability to change appearance."

The witch nodded, "Perfect and worth 40 points to Gryffindor for it. Time for one more, so… Very well, since your hand looks about to be falling off, your turn."

The one that Tonks pointed to was Draco Malfoy, far up the back, who stood with a pompous aura about him, "Why should we listen to a halfblood that is both the daughter of a blood traitor and can't even walk over a flat surface without falling on her face?"

"Cousin, I will tell you and everyone in the class this just once, I hear one more thing about blood or bullying of any kind, not only will I remove 1000 points from your house, I will place you in detention for a month and request that your Head of House personally punishes you. That is your only warning, and don't even bother threatening to go to Lucius, I am an Auror, even if only a trainee," the grey eyes pierced through the blonde's own, letting him know she was serious before breaking the glare and smiling at the class, "Right, let's do this exam. Once you've answered all you feel you're able to, bring it up the front and you can leave for the day."

The exams were handed out, and they were very thick, but the two demigods dove straight in, answering the questions easily and quickly. While the students around them slowed down and the room emptied, Lex and Mia were still going strong. It didn't take long for the room to become empty bar them and Tonks, who was marking the exams piled on her desk.

When the bell for lunch sounded, the purple head shot up and noticed that the pair were still going, and were actually near the end of her exam. Getting up, she noticed that her exam wasn't in English anymore, and they weren't writing in English either, something she would be discussing with her colleagues soon. Standing there she watched as they finished and waved their hands over the paper to revert it to English.

"Outstanding"

The two demigods had known she was standing there and grinned at her as they passed over their exams, "We've done a bit of studying outside of class. Here you are Professor Tonks, all done."

Tonks watched as they left, her brain going a thousand miles a minute. Her stomach then growled, so grabbed her Self-Inking Quill and took the two exams in her hand down to lunch with her, grateful she didn't have any more classes that day. When she sat beside Severus, he spotted the handwriting and smiled internally, "Did they get to the end?"

"Yeah but maybe they missed one"

"No, if Harry and Hermione made it all the way through, they didn't miss any and I doubt they got one wrong," the man shook his head, "They're going to get their bloody masters in every subject before they are legal adults, and they'll drive me grey soon."

The Auror was shocked, "They couldn't have answered every question; they're 2nd years. And what language do they read and write in by the way?"

"Ancient Greek and it is very possible," Filius said from his place on her other side, "Already Miss Granger and Mr Potter are into their 5th year work for my class, I'm going to have them sit their OWLs at the end of the year."

"Same with all the other basic subjects, and they started on the electives last term," Severus told his former student and colleague, "Best thing for you, place them up front and let them go at it at their pace."

Tonks had something else in mind, so went silent and marked the exams, still surprised when she marked every one as being correct, and they hadn't missed any of them. She knew that her idea was perfect for the pair, that is of course if they approved.
