A/N: Someone suggested writing a chapter about Chrona and Ragnarok, but the flashbacks on her childhood just seemed so screwed up. I can't bring myself to concoct a funny situation from it…sorry.

By now, they'd been through everything. They'd been through the hideous STD slides (This could happen to you, kids!), and horrible allegories for menstruation: "So Mr. Uterus decides to make things just right for the baby, if she's ever conceived, by lining his inner walls and stockpiling precious blood." They'd been through every birth control device ever devised by man, and every disease devised by nature.

They'd been through anonymous Q and A. At the end of the day, a brave few ill-informed students would put slips in the Enlightenment Box. Questions would be drawn from random the next day. In most cases, the result was all-too-explicit questions followed by stammered explanations from Cid.When Maka had seen Black Star's attempt at nonchalance while stuffing his question into the box, she laughed. "I think we'll all know it's your question if it ever gets picked." All she got was a scowl at the time, but later she would be proven correct.

That Wednesday, Cid pulled out the only question he'd ever refuse to answer adequately in the entirety of his teaching career. "How does one become-" He squinted as if he were rereading the paper, and his face fell. "How does one become…..very big. And satisfying for the la-. Oh no."

A unanimous sea of eyes swept to Black Star's form. He had drawn attention and, as usual, failed to notice it wasn't the right kind of attention. "HEY, PROFESSOR." He roared. "WHAT'S THE ANSWER TO THAT KID'S QUESTION?" Tsubaki could do nothing but sigh these days, and sigh she did.

"No one knows, Black Star. No one knows." Cid was massaging his temples and wondering why he didn't go for the elementary age group instead. "All right." He trudged on, resolute to move to greater things. "I think we've covered enough of the basics for now, and enough of the safety side. You know the science. What hormones increase when humans fall in love, children? Yes, Maka?"

"Dopamine, serotonin, and adrenaline."

"Good. Tomorrow we'll shift to sex and soul relations." Over the years, Cid had found the knack to make his closing remarks just as the final bell rang.

The next day, no one noticed the kid in a sharp black suit sitting in the back of the room. Instead, they all stopped and stared at the massive TV parked at their teacher's desk. Today was a video day. Soul couldn't resist a high-five with Black Star, and everyone else seemed pleased as well. At the opening bell they all scrambled into their seats. They didn't know the course of their Technician/Weapon relationships would be forever changed by what they were about to hear.

Soon Cid had turned on the video. All the screen held was two lines, blue and red, on a graph. Soon they started to move. They fluctuated up and down, and most of the time they stuck together. Where blue went, red went. "Bo-rrring." Black Star moaned, rolling his r's as he always did. Cid paused the video. "Can anyone tell me what this is? Yes, Oxford?"

"It's a Resograph."

"Correct. Care to explain what a Resograph is to the class?"

"A Resograph charts the synchronization pattern of two souls." Oxford said. He was one of those students who loved to hear the sound of their own voice, particularly during class.

"Yes. This pair is particularly well-synced, and that is because they are a meister and weapon pair. Now I'll display a resograph of the same pair six months later."

After a bit of fumbling and fastforwarding, a new graph came onto the screen. Where the lines had simply been close before, they now occupied the same place. A purple line was in place of a blue and red line, as if they had been mixed together. The class was amazed.

"Is this the ideal pair, Professor?" Oxford asked. Cid shook his head. "No, Oxford, and you'll see why in a minute."

Suddenly, the two lines split and went haywire, spilling into opposite ends of the graph. A gasp ran through the entire class. And they snapped together into a single purple line again. The same cyle seemed to repeat over and over, until they split so far they seemed to exit the graph. The last shift had an air of permanence.

"What happened, class?" Cid inquired. No one volunteered an answer. Cid launched into lecture mode. "Puberty happened. The first graph was of the pair when they were both thirteen. By the time they were fifteen, they were unable to sync again for even the shortest period of time. That's because they fell in love."

Maka felt something curdling in her chest. She wondered what felt so strange, why she felt like she had done something horribly wrong. Even Black Star had nothing to say. He was gazing at the top of his desk. She wondered if he was feeling the same way.

"At first, a romantic relationship between a tech and weapon does wonders for their synchronization. Their wavelengths match to an extraordinary degree. But that kind of connection is unstable. They get absorbed in their own feelings, and get too emotional. They have lover's tiffs during battle. They snap easily in and out of sync. If you've learned nothing this whole year, you'd do well to keep this in mind: The connection that'll keep you alive is a reliable connection. The agitated state lovers are in isn't reliable at all, especially at your blazing hormonal age. The pair here broke up, as most teenagers do. They couldn't work together ever again. Years of training together had to be undone. They don't have the right, and you don't have the right, to jeapardize that secure and platonic bond with your partner. This kind of thing is only exaggerated by sex, as you can imagine."

Too many children were squirming in their seats. Cid plowed on, regardless. "If you have the slightest inkling this might happen, I urge you to go to the nurse's office after school. There's a system worked out to seal out those feelings. It's a harmless operation, and it'll ensure you a stable pattern with your partner for years to come. Yes?"

"Will anything else change if we opt for that?"

"No, Killik. Nothing will change at all."
