Like many things in life, all good things must come to an end. The Changeling's charity work had finally reached its final day. And the day that both Changelings and Ponies were dreading had arrived. All seven Changelings never wished to leave, but they worry for their queen who was abandoned by all Changelings. They had to leave to check on her, so now they must say good bye to those who took care of them until now.
Pinkie Pie hugged her own Changeling so hard until her Changeling thought she was trying to break it, so it couldn’t leave and would have to stay at the hospital. But it somehow survived Pinkie Pie’s death hug, before thanking Pinkie Pie for the last party she hosted for it and the other Changelings, including every little thing she done for them. It said it will always remember the way of Laughter, so if it found anyone sad, it will make sure to find a way to make them laugh and smile.
Applejack gently hugged and comforted her own Changeling who was crying over her chest. It was really honest with what it felt here and cried with genuine sadness. It said again and again that it didn’t want to leave, but declined Applejack invitation to stay every time. It knew the team needed it, the queen needed it, so it had to go...Applejack wished it good luck on its journey and gave it saddle bags filled with Sweet Apple Acres apples, telling it to lie only when it was absolutely necessary and to never forget the way of Honesty.
Rainbow Dash still won every race she had against her Changeling, even as her Changeling tried hard to win against her until it finally become the fastest Changeling in the end. It told her it will train harder always and will return to challenge her for victory. Rainbow Dash smiled and said that she will always be here to accept it challenge when they would meet again. Deep down inside, she wanted to ask it to stay with her, but she knew, that the way of Loyalty she taught this Changeling means it will not abandon its friends, even for her.
Fluttershy and the other animals came to say good bye to her Changeling. Her Changeling cried a bit when it saw that all the animals were here for it, all willingly giving it final doses of love for its journey. The Changeling said it will miss them all, especially a little white squirrel that attached itself to it the most and helped it take care of the many animals all this time. But to it surprise, it showed that it wished to be Changeling's pet and go on the journey with it. The Changeling looked at her former keeper and asked if she was alright with it. Fluttershy nodded and wished both of them the best of luck. The Changeling hugged Fluttershy and said it will always remember her way of Kindness and would make sure to spread it to everypony it meets on its journey.
Rarity prepared four season clothing for her Changeling. She wanted it to be as comfortable as it could be on its journey. She told her Changeling that her boutique door was always open for it when it would return. She expressed that it was the best work partner she ever had and wished that someday she could entrust it to take care of one of her branches of the boutique. Her Changeling said it will remember her offer and promised to remember her way of Generosity.
Twilight told her Changeling that it didn’t need to go; it could stay here because she thought that someday, Chrysalis will return to her in the future, no matter if she would come here for revenge or help. But her Changeling said it couldn’t do it, it knew that their queen wasn’t exactly the best, but she was still their mother. She was willing to do many bad things so that her children could survive. But now, every Changeling at the hive had all abandoned her. It didn't know how she might be feeling right now, but it was likely to be very bad, and all it wanted was to make sure she was alright. It wanted to return to take care of her, show her that some Changelings still appreciated her efforts and won’t abandon her. Twilight understood its reasons and gave it a survival kit, map and many useful books for its long journey. Twilight hoped for it to return to Ponyville someday as an ally, not as an enemy...She wished her way of Friendship will make Chrysalis see the light someday....
Spike held his Changeling's hand and wished for it to have good luck on its journey. But somehow he could sense this Changeling still had some doubt in its decision. So he asked it if it was worried about something in particular. It said that it was afraid that it will become a useless sidekick again...It wasn’t sure if it was a good idea for it to go with the team, it didn’t want to be a burden on the group, it didn’t want to slow the team down on the journey to search for their mother...Spike smiled and told it that it was his number one student. He believed that it can be the good support of the team. It should have more confidence in itself and if it had any problems, it could always send a letter to him with the fire-spell he taught it. It listened to his encouragement and smiled, before it wiped away its tears and said that it will make him proud. The way of the good supporting assistant will always be with it.
All six ponies and one dragon observed all the Changelings remove their disguises and return back to their normal-selves once again. They waved good bye to them and they began flying away horizontally, wishing them all good luck and hope for them to return someday...
"In the end of Season 6, the Mane 6 returned to their home and found that their imposters (Black Changeling) were all still here. After hearing about how their queen had lost and that a new king had ascended, they surrendered to the Mane 6 and they were forced to do charity work to atone for their crimes while under the Mane6’s supervision. However, they refused to give up the love they currently had in order to become colorful Changelings and join Thorax's hive, saying they will find their old queen once they had atoned from all their crimes.
The Mane6 let these Changelings turn into Changeling versions of themselves, to better identify which pony each Changeling belonged to."
