Before Georgina, Rabina, and Lucy were born, Voldemort was in the healers clinic, putting their plan into motion.
Voldemort was cramping that day, and raised their wand against the healer. Voldemort realized why Bellatrix was immune to the crucatio curse. Why did Bellatri, Carrow, and Narcissa never tell then that cramping was worse than the crucatio curse? This was why Bellatrix would lie down with a bottle of hot water and smirk whenever Voldemort hit her with a crucatio. Damn her and her religous zealot child.
The healer moved quickly and brought the eggs outside. She dumped engorged potion on them and they grew big enough to see without a magnifying charm. 10 bees stung one egg each, which looked the bees.
While this was happening, Voldemort completed the horocrux ritual. After the eggs had horicruxes and would live forever, the heater shrunk the eggs back to their original size. Then she checked them to make sure they were fine, they were infect very healthy.
Once they were back inside Voldemort, Voldemort raised their wand on the healer. "Wait," the healer cried. Voldemort didn't lower their wand, but still waited.
"Since wizardkind existed, no one ever made eggs last forever, even with magic. You can have kids at 100. We'd love to have you work with us, your research is gold!"
Voldemort waved a manicured hand. "Maybe layer, my reldest daughter is a relgious zelot and may destroy places of learning for alchemy, healing, and potions. But at the same time she wil be the only witch to realize arithmancy is numerology or the divination-ish practice of assigning numbers to letters, not muggle math." Then Voldemort placed a modified memory charm on the healer.
After a day of rest, Voldemort hunted down the unloyal, unfaithful cheaters Rabastian and Barty. You-know-who on their you-know-what was bone chilling. And demanded extra sanitary products.
Unknown to anyone, voldemort was on the end of their period so one egg with a horocrux was still fertilized, after it split in three.
9-10 months later Georgina Lestrange, Rabina Lestrange, and Lucy Crouch were born.
And three years later a very pious five year old Delphi would be seen selling crafts at a stall near her church of Greater Good. She was raising a good chunk of change for Mother's Day. Delphi currently had had 200 galleons on her wizarding prepaid paycard. She would buy her mums anything they wanted. She's been a busy little bee at her holy lemonade and craft stall hustle. She forced her little toddler sisters with auburn hair to help her at the stall set up. outside her church. And then they had to massage her little legs at the end of the day.
"Use that 50 galleons for a gift for mum2, heathens," Delphi told them, braiding the Georgina, Rabina, and Lucy's hairs together. She couldn't tell them apart, anyways. "You never know when Voldemum will have more kids. Best let her remember you were her favoritist kids when a civil war starts between the Riddle-Lestrange Heirs."
"Okay Delphi," they chorused. The triplets obbegin crafting things to sell at the stand as best the year olds could. "And remember to earn brownie points" Delphi added.
The triplets ran off to butter to to voldemor tumbling because their hairs were braided together. As they wailed, a house elf appeared on hearing their wail like a command, and scooped them up before taking them to Voldemum.
