"Perhaps one day I can repay you," Chrom said to the mysterious Marth.
Lucina opened her mouth to reply, but before she could respond a small girl with blue hair dropped out of thin air, and proceeded to land on top of her.
"Oof," Lucina grunted from her splayed out position on the ground. Glancing at the small girl that was groggily trying to sit up, Lucina's body froze in recognition. For the little girl who had appeared out of nowhere was a younger version of herself.
However, once again she was interrupted, as a 4 year old boy, a 3 year old girl, and an infant boy also popped into existence in the grass right next to her. This set the four and three year old into an intense round of giggling while the littlest boy started to whimper in preparation for a more intense crying session.
"Itsuki!" the small Lucina squeaked in panic as she scrambled off her elder counterpart and quickly gathered her youngest sibling in her arms. As if by magic, this seemed to return the little baby boy back to a state of complete and utter calm.
"Papa!" said the four year old boy with a grin towards the shell shocked form of Chrom. He waved at his father. "Hi!"
"Hello," Chrom said automatically. He seemed a bit bewildered by the new title that had been bestowed upon him.
"Papa," said the three year old girl as she walked over to her father. She held out both her arms and said a single additional word. "Up."
"Morgana," the little Lucina admonished her sister.
Morgana seemed to ponder her sister's wise words for a moment, before nodding to herself and looking back at the confuse face of her father. "Papa. Up, please." Chrom obliged her fairly quickly, and the young princess of Ylisse rested her head on her father's shoulder.
"You look remarkably like Robin," Chrom muttered to himself, although not quiet enough that Lucina couldn't hear. "If we weren't already engaged I think I'd be even more confused by this than I already am."
Lucina's brain tried to stop her mouth from wagging. It really did. But there was no stopping "Father, you and Mother got engaged this early in the timeline?" from slipping out. Her father's sharp glance in her direction told her he both heard and understood the implications of her little gaff.
"Chrom?" said the voice of Emmeryn from behind her younger brother. "What's all this, then?"
"This is going to sound ridiculous, Emm, but I think it's time travel," Chrom replied as Phila, Robin, and Frederick joined the strange group of blue haired children.
"Mama!" squealed the four year old Morgan right before he ran towards the tactician. Almost on reflex, Robin bent down and picked up the little boy when he got close enough to her arms. "It's like picking up a little Chrom," she breathed in adoring wonder.
"I knew milord and Robin were in love, but I wasn't sure it was strong enough to turn into a lasting marriage," Frederick said. He raised an eyebrow at the blue haired brood that had attached themselves to various members of their family. "It seems my worries were unfounded." The knight seemed to do some quick calculations in his head, before throwing a slightly disapproving look at Chrom. "One wonders if it was really necessary to bunch them all together like this, however. Really, milord, there is milady Robin's health to consider."
Chrom didn't really have a good response to that, since he technically hadn't even fathered any children as of that moment. He did, however, flush quite deeply in response to his knight's insinuations.
"Hi, Auntie Emm," the small Lucina said after she had walked closer to the Exalt. "Would you like to hold Itsuki?"
Emmeryn barely managed to hold in the gasp that emerged in response to seeing the brand of the Exalt in the small Lucina's eye. Thrown off by this, she too took a small blue haired child into her arms in an automatic fashion.
Itsuki looked at his aunt gravely, and the Exalt looked into her nephew's eyes with a graceful solemnity. After a few moments, the little baby boy was satisfied and promptly fell asleep.
Lucina (the elder) quickly threw away any pretense of pretending to be someone else, and asked a question of her younger self directly. "You know who Aunt Emmeryn is on sight, Lucina?"
The younger Lucina rolled her eyes. "Duh, big me. She and Uncle Priam visit us every few months."
The normally perfectly reserved and somewhat stoic Exalt of Ylisse seemed to freeze at the implications let loose into the wind by her young niece. "Lucina," Emmeryn said gently with a hidden note of panic and wonder in her voice, "are you saying that the Emmeryn from your time is married to a man named Priam?"
"And quite happily married at that," said Chrom's voice from behind Emmeryn. Except that Chrom was in front of her. Which meant….
"Papa!" Lucina said with a smile on her face as she waved to the new group of adults behind her Aunt Emmeryn's back. "Did you know that there are two of you here, Papa?"
An older version of Chrom smiled indulgently at his daughter, an arm around the shoulders of an older version of the tactician Robin. Both were dressed in finery that made it quite clear that Chrom was the Exalt and Robin was his queen. Upon seeing the calculating looks of his family's younger counterparts, he let his smile drop and spoke directly to the unmarred face of his elder sister. "Sorry for intruding upon you so suddenly, Emm. The method of our arrival was an unfortunate necessity, or so Naga has led us to believe."
The elder Robin picked up her eldest daughter and smiled wryly at her husband. "Are you implying that the Divine Dragon Naga deliberately dropped one version of our daughter on top of another for her own amusement, my husband?"
"I've spent enough time around Lady Tiki to come around to the fact that the apple doesn't fall far from the tree."
