"So that's how my sister and I got our names!" Precious Treasure commented after hearing the story, "I can't believe that she's missing this out!"
"But the next part of the story is not as good as the others..." Yona warned, "And it is not so romantic."
"Well, in that case, I'm listening." Sparity showed up, having overheard what Yona said about the upcoming part.
"Alright then, not long after Sparity hatched, Rarity had a lot of problems." Yona explained.
In a flashback, Rarity was galloping around Carousel Boutique, in a hurry.
"Sapphire Shores will be here tomorrow! And her dress must be divine!" Rarity told herself, "How can I lose it right after placing it where it won't be lost?"
Rarity turned around the corner and found something unpleasant: Precious Treasure and Sparity were nibbling and drilling on the dress for Sapphire Shores!
"Bad babies!" Rarity scolded, "That's it! I've had enough of being patient with you! Ever since you were born, I can barely get some sleep, every time I take you out to see Spike, you cause a lot of problems that delay me, like you always do, worst of all, you are preventing me from doing my work! My job! Especially when I'm a well-known designer! This is the last straw!"
That night, after accomplishing his Friendship Ambassador duties for the day, Spike returned to Canterlot to retire for the night, and message his beloved Rarity. But when he opened his magical book, he was shocked to find a message that he wished that was not real: "Spike! The kids have caused me too much trouble! And since it is your idea, I have made a decision, to want nothing to do with you! I sent the kids away to be adopted by Lyra and Bon Bon, to take away our status as a family! Because I'm through with you! We are officially broken up!"
Spike was in tears to learn what Rarity did, "How could you? We're friends!"
"Spike, what is wrong?" Princess Twilight Sparkle asked, approaching her adoptive little brother.
"Thi is what's wrong." Spike sadly handed the message to Twilight for her to see.
"How can Rarity do something so awful like this?!" Twilight asked.
"I think she got too much pressure...because of me..." Spike sadly stated.
"You know wha, Spike?" Twilight asked, "As the Princess of Friendship, every friendship problem I know is something that has to be taken care of! I'll help fix this problem, and I'm going to do it now!"
Later that night, Spike and Twilight visited Lyra and Bon Bon's house, where they retrieved the babies and apologised for having to take them back when Rarity confirmed that Lyra and Bon Bon could keep the infants. The two mares accepted the apology and figured that they would not be very good adoptive parents.
Spike comforted his crying children, "Don't worry, Daddy's taking you back to Mummy."
"And Aunt Twilight is helping!" Twilight Sparkle added.
In Carousel Boutique, Rarity was designing a new dress for Sapphire Shores just before she heard a knock on the door. "Come in," she said, before Spike and Twilight entered.
"Oh, it's you, Spike." Rarity huffed, looking unhappy and a bit angry.
"Rarity, please don't be mean to the babies, they're your family for creature sake!" Spike told the unicorn, but got a response that he could never imagine.
"They may be my biological offspring, but I disown them! And since you're too busy with your duties, I figured that Lyra and Bon Bon could take care of them as their adoptive children or something!"
"But, Rarity! You're their mother! Plus, you figured that you would like to have them for the future generation of Equestria!" Spike reminded.
"At least they are still alive, that's what matters," Rarity coldly pointed out.
"WHAT?!" Spike asked in shock, "You only care about them being alive, and not how they live?!"
"Spke, they are nothing but trouble, even before they were born!" Rarity harshly shouted, causing the infants to cry.
Spike handed Precious Treasure and Sparity to Twilight before confronting Rarity, "Rarity, that is it! You've crossed the line with how horrible you are to our kids."
"Our biological kids, but not necessary our kids anymore." Rarity coldly explained, ""I already said that we are officially broken up! And I sent the kids to Lyra and Bon Bon, to be adopted by them, and take away our status of being a couple!"
Heart-Brokered, Spike cried out, "I can't believe I had a crush on you...since I first saw you!"
