Two months have passed since Chloe and Aylene have become sisters (and since Aylene got adopted by Celestia), and it was also fourteen months (one year and two months) since Chloe first arrived in Equestria), and it was also six months since Chloe turned 9 years-old, but there's still somthing both Chloe and Aylene are missing and that they still need for the most - a father.
Celestia and Luna were the mother and main auntie for both Chloe and Aylene since Black Heart abused Aylene and escaped before she can be capture and imprisoned, but they still wanted to find the perfect father figure for both Chloe and Aylene, because they knew that that's exactly what they're both still missing and waiting for the most, and so she decided to send both Chloe and Aylene to the changeling kingdom so they can befriend the colorful and love-filled changelings, whom are the loyal following subjects of the king of the changelings who dethroned the original ruler, Queen Chrysalis, and banished her from the changeling hive - King Thorax.
One day, Celestia and Luna decided to send both Chloe and Aylene to the changeling kingdom to befriend the friendly, kind and love-filled changelings, and so they called the mane seven (and Spike), and another pony, a Unicorn mare who is a traveling magician who was once an enemy of the mane seven (before and after Starlight's redepmtion), now an ally and a good friend, Trixie Lulamoon, to take Chloe and Aylene with them to the changeling kingdom so they both can make friends with the changelings, and maybe even pick up one of them as a father figure for the both of them.
On their to the changeling kingdom, Trixie introduced herself to Chloe, and explained that she was once the enemy of Twilight and of her friends, but also quickly added that she eventually changed and became a better pony, and that her most closest friend is Starlight, much to Chloe's amazement, and then Trixie referred herself in front of Chloe as "The Great and Powerful Trixie.", due to because she tends to talk about herself in a third person, or in her case, in a third pony.
Once everypony finally arrived at the changeling kingdom, Chloe and Aylene were both amazed to see how beautiful everything around them looked like, and then everypony too them both with them to introduce them to the changelings, and then they took them to the throne, where an adult male stag-like changeling with two large antlers which are shaped like ant mandibles, and a bit smaller but older male stag-like changeling with two smaller antlers which are also shaped like ant mandibles sat side by side. They where Thorax, the king of the changelings, and his older brother, whose name is Pharynx.
When Thorax met Chloe and Aylene for the first time, he reconized Chloe because of her being a human, and then he said to her "I've already heard of you as the good human who arrived in our world and is now living here!", and then he added "Cadance and Shining Armor told me so much about you, and thanks to them I also know your name is Chloe, and that Celestia have adopted you as her daughter!", and then he said as he warmed up to her "And every human who is good and kind and is adopted and respected by the Alicorn princesses as a son or daughter is also a friend of us non-ponies too!", and then Pharynx also began to speak to her.
"Wow, you're really a human, and I've never seen a human like you before!", and Chloe explained to him "That's because I'm a female human, and I'm also a girl and not a full grown woman!", and then she added "Anyway, it's so nice to meet your brother, Thorax the king of the changelings! He's the most benevolent father figure for all of the changelings in his kingdom!", but then Pharynx said to her "But I'm actually his older brother, and before I've changed, I was an aggressive and harmful changeling, just like all the changelings have been like in the past, when Chrysalis ruled, except for one changeling who was benevolent from the day he hatched - my younger brother, Thorax! And today he's both the leader and the king of the hive, but he rules in a good way by teaching us changelings not to feed on love and instead share it with others, and that's how all the changelings have changed! Well, except for Chrysalis!".
Then, Twilight introduced Aylene to Thorax and Pharynx and then she explained to them about her becoming Chloe's sister after she's been adopted by Celestia too, and that the reason for this it's because her real mother, Black Heart, abused her, beaten her and blamed her on her father's death, and she also forbade her from befriending both other ponies as well as all kinds of non-ponies, including all kinds of forest animals.
When Thorax heard everything about Aylene's life, he asked Chloe what her own life was been like, and Chloe explained that before she arrived in Equestria, she's been abused by her own parents as well as her older brother after her grandmother died, and that they blamed her on her grandmother's death and even tried to feed her to the tigers at the zoo to get rid of her for being kind and gentle and because they hated her so much, and that she suffered the same or worse life compared to Aylene's life.
Thorax was shocked to know that both Chloe and Aylene were been abused by their own families (respectively), and so he said to them both "You can stay here and befriend my changelings, and maybe one of them will be a father figure for the both of you!" and then added "Now go and befriend my changelings! They all truly like to share their love and friendship with the ponies who gave them these, as well as with other creature alike!", and then Twilight said to them "Go and have fun with the changelings!", and then she and her friends all turned to go, and Chloe asked them what they're doing, Twilight explained that she'll come back with her friends to pick her and Aylene up tomorrow afternoon, because she and her friends want to give both her and Aylene enough time to find and choose one of the changelings as a father figure for the both of them, and then Twilight used her magic to teleport herself and her friends back to Canterlot to inform Celestia and Luna about the mission they gave Chloe and Aylene which is to find and choose the changeling they love for the most as their father figure, thus leaving Chloe and Aylene behind in the changeling kingdom.
Meanwhile, Yigal, Gilad, Ezra and Black Heart all have arrived at the changeling kingdom and they're now searching for both Chloe and Aylene, and they're not alone - their six animals also came with them to make sure Chloe and Aylene won't be able to escape them. "When we find my daughter, I'll be cruelly trapping her in a basement for the rest of her life if she ever dares to befriend a bunch of filthy changlings!" Black Heart said with an angry face, but then Yigal placed a hand on her shoulder and then he said to her "It's okay, Black Heart, we'll find her and that stupid girl, Chloe, and then we'll give the both of them just what they truly deserve for being such a couple of disappointments to us!", and then they all continued to search for Chloe and Aylene in the changeling kingdom.
Meanwhile, Chloe and Aylene managed to befriend some of the adult changelings, but they still don't know which changeling they should choose as their father figure. Then, the two met a young male changeling who is around their own age, and when they asked him if he wants to be their friend, and he accepted befriending them both, before he stretched his hoof out for them to shake it. However, as Aylene was about to be the first to shake the young changeling's hoof, some larger hoof suddenly came out of nowhere and punched him hardly in the face and it caused him to fall down as he got knocked unconscious.
When they both saw the young changeling being knocked unconscious right in front of their eyes, Chloe and Aylene both looked in shock, before Black Heart suddenly jumped out of nowhere and appeared right in front of them with an angry face, before she approached her daughter and then she came close to threaten her as she shouted angrily at the Pegasus filly "WHAT ARE YOU DOING?!", and Aylene asked in shock "Mother?! Is that you?! What are you doing here?!", but then she slapped Aylene across the face and then she shouted at her "Changelings are dangerous non-ponies! You deliberately disobeyed me! You're not even supposed to make friends with them! Even if they're around your own age!", and then she slapped Aylene's face again, causing th Pegasus filly to cry in pain as she couldn'y bear the new and fresh injuries that started to form on her face, and this made Chloe angry as she's about to attack Black Heart to come to Aylene's help, but then she's grabbed and got pulled back by one of her wrists by force, and when she turned her head to see who's pulling her back, her eyes widened in shock and horror to see Yigal pulling her towards him by her wrist to prevent her from saving Aylene.
Then, Gilad came out of nowhere and then he slapped Chloe twice across the face, and then Ezra also came out of nowhere and then he said to her "You and your friend are ours and ours alone!", and then he, Gilad and Yigal all laughed evilly, before Gilad managed to grab at Chloe's other wrist to capture her, while Ezra came for the back of the neck to restrain Chloe like a wild animal, and then Tony Black came out of nowhere with a strong rope in his mouth, before he stopped dead in his tracks when he reached Yigal, his brothers and Black Heart, the black Bengal tiger dropped the rope from his mouth to allow Yigal, his brothers and Black Heart to tie up both Chloe and Aylene to make sure neither of them escapes, and so Yigal and his brothers cruelly tied up Chloe, and Black Heart joined in by cruelly tying up Aylene with the human girl together, thus capturing them both at once.
"Let us go, you monsters!", Chloe shouted at the three adult human males and at the Pegasus mare, and then Aylene asked "What do you want from the both of us?!", but then Yigal slapped them both across the faces with his large hand at once, and then he evilly said "You two are coming with us! Do you both understand?! You're not going anywhere without us! You two are ours and ours alone!", and then he, Gilad, Ezra and Black Heart all lifted and carried the two tied friends and sisters up and then they placed them both on top of Lin Raju's back, and then Ezra told the Mammophant to go, and he obeyed his human owner, and so Lin Raju began to walk away while taking Chloe and Aylene captive with him, and then Yigal, Gilad, Ezra, Black Heart and all the five other animals followed close behind as they all began to leave the changeling kingdom.
When nighttime came, every changeling went back to the hive to go to sleep, except for their king, Thorax, who is still worried about Chloe and Aylene since he haven't seen either of them in hours, and so he decided to go and search for them so he can take them to the hive to sleep with the rest of the changelings. However, after Thorax searched everywhere in the changeling kingdom for Chloe and Aylene and haven't found them, he realized that they're gone because they got kidnapped by Yigal, his brothers, Black Heart and their animals (upon finding their footprints which they all left behind), and after he followed the footprints, he ended up seeing them leading out of the changeling kingdom, much to his shock and horror to know that they all took Chloe and Aylene hostages and took them away from the changeling kingdom.
Thorax said "Oh no! Chloe and Aylene got kidnapped! I must send a letter to Princess Celestia! She must know about this!", and so he began to write a letter to Celestia about Chloe and Aylene's disappearance, and once he finished, Thorax sent it to the royal castle, and he hoped that by the morning Celestia, Luna, the mane eight and the royal guards will help him, Pharynx and their changelings to search for Chloe and Aylene so they can find them and give Yigal, Gilad, Ezra and Black Heart what they all deserve for kidnapping the human girl and Pegasus filly and taking them hostages.
