It wasn't as though Pyrrha was expecting anything unusual to happen today. Just her standard Saturday routine: Do some training, join her team for breakfast, then some relaxation time. Nora had been pestering her for the last month to just ask Jaune out, and as tempting as it was...

She just couldn't muster the courage to do it. This feeling of cowardice made her frown as she jogged on the treadmill in the school gym.

She wanted so badly to just be honest, but... The prospect of rejection froze her to her very core. How could she make him understand that she'd fallen for him at first sight? Even someone as socially inexperienced as her realized that it would sound crazy. She had lived most of her life wearing masks, concealing her true feelings. It had been vital for survival and success, but now?

It paralyzed her with fear at someone seeing the real her. Especially Jaune.

Ha... The Invincible Girl, afraid of being rejected by the one she loves, she thought with a mental sigh, It would be funny if it wasn't so sad...

After finishing a workout that would kill an Atlasian Specialist (her daily routine), Pyrrha went to the showers, washed up, and emerged in her school uniform. She paused as she entered the hallway, and frowned.

Wait... That's another electromagnetic field powered by Aura... Why am I feeling another-?

"Hello Mother."

Pyrrha started and turned around. Her jaw dropped. The young man before her was... Was tall. Redhaired, with deep blue eyes, aristocratic cheekbones, and a pointed chin. He wore armor similar to hers, but with segmented plating under strong pauldrons. A red cape hung from his shoulders, and a leather band was around his head under his short hair. A Clipueis shield was on his back, while a mechashift Spatha hung from his belt. His walk was confident, but not arrogant-Almost painfully familiar.

Pyrrha blinked a few times. Her mind went to the most likely possibility for this unusual young man to be standing before her calling her mother.

It was a fairly short list, after all.

"Um... I have run into stalkers before, so, I'm sorry but I can't be your-" Pyrrha began, as politely as she could. The young man shook his head and groaned. He held up a hand to his face, and calmed himself before he spoke again.

"Ugh, no, I'm not a stalker. I'm..." He sighed again, and looked right into her eyes.

"Okay... You told me that you fell in love with Dad from the moment you pinned him to a tree in the Emerald Forest during your Initiation. Is that true, or false?"

Pyrrha's jaw dropped. Her face went bright red.

"I-You-What do you-?!"

"I know this is going to sound crazy, but I'm your son Xander," he introduced himself, "I'm from the future. My best friend, Moses, has a time travel Semblance. We accidentally got sent back in time... To the day of your first date with Dad. Jaune Arc."

Pyrrha continued to stare in shock. Xander bowed his head.

"I know how it sounds. This-This isn't a scam. and I know it's a lot to take in, but..."

"Eeeeeeeeeee...!"

Xander started and gaped at her.

"Mom?"

Pyrrha's shock slowly turned... Into an ascendant joy. A joy she just couldn't keep contained as she squealed softly.

She grinned, her eyes lit up, and her soul seemed to fly!

Her keen mind rationalized that this was too insane to be a scam of some sort, and who would know of when she fell for Jaune but her own son? She would tell her children the story, over and over, with their father, her Jaune, her Jaune, alongside! Share with them all the love and affection she was denied in her life, and make sure her children knew they were the product of true love!

She hugged her tall son, and it felt like the most natural thing in the world. She beamed up at him, and relief flooded his face.

"I believe you," she said. Xander grinned and hugged her back.

"Thanks Mom... Thank you... That means everything. Though uh... We might have a problem. I mean, along with the date-"

"What problem?" Pyrrha asked, maternal concern emerging in her heart as naturally as breathing. Xander winced.

"Um... Basically, if you don't go on that date, I will never be born. And uh... I've got a lot of temporal half-siblings. Other kids from other timelines where Dad... Didn't marry you."

Pyrrha's jade eyes narrowed.

"What."

"I-I mean, if I'm the destined son of Jaune Arc, then you know, it doesn't matter, but they're all going to try to hook Dad up with their mothers to-"

"What."

Xander cringed as Pyrrha's face became grim. Oh, she could be a scary mother. Good to know. She hoped she would be loving but also able to command respect and fear when necessary. Mostly love! But also fear where required. She wasn't going to raise her kids like her mother did!

"Um, yeah, so they might be gunning for Dad and then my siblings and I will never exist-"

"What."

Pyrrha pulled out her Scroll and summoned her locker. The rocket locker flew in through the open archways. The moment it was in range, she yanked it down to the floor with Polarity so hard it left a crater in the tiles. She yanked out her gear and got dressed in no time. She swung back around, Milo and Akuo in her hands. She didn't pay any mind to Xander's embarrassed blush.

"M-Mom, did you have to change in the middle of the-?"

"Yes," Pyrrha said, slamming her shield and sword together hard enough for sparks to fly off them, "Nobody's erasing my baby from existence. Let's find your father!"

Xander grinned in relief, and it filled her heart with song.

"Thank you Mom... That means everything to me."

"This means everything to me too, son," Pyrrha said. Her serious countenance broke for a moment into a shy blush.

"Just... Out of curiosity, how many children do your father and I have?"

Xander smiled.

"Uh... Nine? I think you were trying for a tenth when I left but-"

"Eeeeeeeeeeee!"

Xander stared at his mom. Pyrrha coughed and shook her head. The excited teenage girl retreated... And the Spartan warrior emerged.

"Come on son... We're getting my man."
