Harry stepped through his office door along with his wife who took a seat next to him at his desk.

With the flick of his wand, a giant yellow arrow (with feathers, of course) hovered around his wand.

"There is no need for introductions," said 'Professor Granger', "as our beloved headmaster introduced me yesterday right before the great show of Mr. Potter, Mr. Black, Mr. Pettigrew, and Mr. Lupin." The arrow floated around and pointed to each in turn.

"Now," he said and made the arrow dissapear, "there is no need for that as we go through the rest of roll call. And may I say now, gentlemen, that absolutely no pranks will be tolerated."

"None at all," he said before James started to groan. "Unless, you plan on giving up your spot of captain of Gryffindor house."

A knock rang throughout the classroom. Professor Granger went over and opened it up. "I sure do hope you're not abandoning class on the first day of school, Professor," he said, to Professor McGonagall.

"No," she nodded curtly, "but I need Potter for a moment. About last night's showing and-"

"to tell me I made Captain," he finished.

"Yes, but-" she stuttered.

"Ah," said Harry, as he tapped his head, "but I knew," which earned him a slap from his wife.

"What!" he said, "I did! Plus, there should be no slapping, as well as no pranking in this class."

"You did that just for me!" said his wife.

"Yes, so what if I did? I may also have done it for someone else."

Professor McGonagall stood gaping for a second before she straightened up and said, "well, Potter, Black, Pettigrew, Lupin. I need you all in my office for detention at eight every night this week."

"But Professor! Quidditch," said Black.

"Then Potter will have to schedule it earlier in the evening, now, won't he?" and with that, she left.

"Put-" started Harry.

"Do you have a wish of two detentions a night?" he asked as he started a spell.

"What?" asked James.

"Put. It. Away."

"There will be no wands out unless I say so. Understand?"

James and the class mumbled.

"Understand?" he asked again.

"Yes, Professor," everyone chanted.

Harry sighed and turned to his wife. "And this was supposed to be a fun class, I didn't want to have to yell on the first day nor teach a lesson. I didn't have one planned."

"Awh, Professor! We don't need a lesson," said Sirius.

"You don't?" asked Harry.

"No! This could be a study hour!" he said.

"On the first day of school?" asked Harry.

"Well, erm-"

"But, I agree. You don't need a lesson on the first day. I was gonna let you ask questions," he said, "but since you all want a lesson…"

A hand raised. "Yes Rachelle?"

"How old are you?" she asked.

"Turned eighteen this past July," he said.

"He's married!" someone hissed and Harry rose and eyebrow.

"Might I add," he said, pulling his wife next to him, "that this is my wife. We got married not even a month ago."

"How'd you get the scar on your forehead?" asked someone.

"Ah, hand please. Yes, Elizabeth?"

"How'd you get the scar on your forehead?"

He sighed and ran a hand through his hair. "Nervous habbit," he said before Lily could raise her hand.

"Stop it!" hissed his wife.

"What? Oh, yes, really should."

"I got the scar when I was one. Someone cast a spell on me and it backfired. It killed my parents, too."

"Wow," said someone.

"I didn't know it could happen that way," said Lupin.

"Well, it- really didn't happen… in that order, I guess. Next question."

"How did you know what I was going to ask? And that James would be Captain?" asked Lily.

"Uhm, well… that's kind of- an unfortunate- uhm, side effect? That should not, ah, of really been asked, but that's not your fault."

"When you battle as often as my husband has and for such a dark cause and with the same person, it often shows that once in a while… uhm…"

"Powers can be switched," read John. "It's extremely rare, happening in an approximate one out of one hundred cases ever studied. It's so rare, in fact, that half the people end up dieing from the loss of power on their behalf and-"

"-and the sudden surge on the other's," finished Hermione and added, "sorry, mind blank, Harry."

Harry blinked and stared at his wife. "You know what you basically told them?"

"What?" she asked without worry.

"That I'm more powerful than the average wizard."

"I didn't-" she started, "ooo… but, I did, didn't I? Oops?"

He sighed.

"Again?" asked Hermione and Harry nodded. "I'm really sorry, Harry."

"It's alright, Hermione. No, that's alright, I'll do it by myself."

"Ah," she nodded in understanding, "selective?"

He sighed again. "yeah, hopefully I won't have to say everything all over again…"

"I'm sorry, Harry," she said truthfully.

"It's alright, I know you didn't mean to do it, just like I didn't mean to."

He sighed and this time erased only the memory of this conversation and the fact that he knew what they were going to say. He sighed. That was the fourth memory charm he had placed on this class within the last hour and a half. Luckily, the bell rang shortly afterwards and everyone got up to leave. Hermione had fun giving people a pick-me-up charm as most of them couldn't remember what their Professor and his wife had been talking about moments ago. As soon as the charm hit them, thought, they really didn't care…

For the next class, Hermione sat down with Harry's journal.
