Three weeks have passed since Agatha announced her redemption to the good side to all of Ponyville and Canterlot (and also to the changeling kingdom), and now she's living quite happily in Carousel Boutique with Rarity, Sweetie Belle, and the two orphan baby Liontaurs, Simba and Sirga, who are also living in Rarity's home, as she (Rarity) was the pony who chose to adopt and take them both in, but when Agatha also came to live in Carousel Boutique, she met the two baby Liontaurs and grew attached to them rather than growing angry and jealous of them (like she did with baby Dan Ashmor before she left Yigal and the other villains for good), and Simba and Sirga, who both felt the same way for her, decided to stay near and next to her and look up to her at all times ever since they first met her, just like how loyal children treat their own parents.

This behavior of Simba and Sirga showed that they actually want Agatha to be their new mother (after and since Terrence killed their own and biological mother when she tried to save Bluebell from getting choked to death by the evil bull elephant), and when Agatha realized that these two baby Liontaurs really think and care much about her, she decided to take them in and become their adoptive and surrogate mother after Rarity told her the painful truth about their own and biological mother's death at the hind leg and foot of Terrence (since the evil bull elephant kicked her too hard when she tried to save Bluebell from him), and ever since Agatha became Simba and Sirga's adoptive and surrogate mother, she felt happier than she ever felt before.

However, one day, the royal family from the Crystal Empire (Shining Armor, Princess Cadance and Flurry Heart) and dragon lord Ember (from the Dragon Lands) came to visit in Canterlot on the same day and at the same time, and when they arrived at the royal castle all together, they're greeted by Celestia and Luna, as well as by Shujaa, Chloe, Aylene, Stephan, and even by Tah and her son Trog, but they aren't the only ones who greeted them - Aron, Zach and the other girls (Bluebell, Linda and Layla) also greeted the Crystal Empire's royal family as well as the dragon lord at the same time, and all the baby and toddler centaurids (Stephan, Linda and Layla's respective younger siblings) all did the same.

However, when the mane seven, Spike, the CMC, Kenai, his two good toddler Beartaurs Kayden and Tallulah, and the baby Liontaurs Simba and Sirga came into the throne room to meet the Crystal Empire's royal family and the dragon lord, they all greeted them and welcomed them for their first shared visit in Canterlot, but when Agatha also came to the throne after all her new friends to meet the Crystal Empire's royal family and the dragon lord, Shining Armor, Cadance, Flurry Heart and Ember all gasped in shock at her presence and their faces suddenly turned pale white when they saw Yigal's former lioness who have recently betrayed him and ran away from him when he, Tony Black and all the other villains have turned her away in order to care for baby Dan Ashmor, thus showing that the Crystal Empire's royal family and the dragon lord were all horrified to see her again after everything bad she have already done for all these years to all of Equestria, long before her eventual redemption.

However, this time, it wasn't Shining Armor who appeared angry and disappointed to see Agatha like he previously did with Kenai, but it was Cadance and Ember, who both appeared angry and disappointed to see Yigal's former white lioness, instead of Shining Armor himself. Then, Cadance lit up her horn and threatened to blast at Agatha with her magic, while Ember clenched her own hands and claws and into fists as she too readied herself to attack the white lioness if necessary, but Agatha seemed less interested in fighting both the Alicorn princess and the dragon lord, and so she kept herself calm and waited for the two to speak to her.

Then, Cadance asked in an angry tone "What are you thinking you're doing here?!", and then Ember added "Who let you just walk into the royal castle and into the throne room to meet us just like this?!", but then Agatha said "Hey, it's okay, I mean you no harm no more. I've changed.", but then Cadance asked as her brows furrowed in anger but also in curiousity "Why should we believe you?!", and then Ember added and pointed out "You're Yigal's evil lioness! Every creature knows that!", but then Rarity stepped forward and she put herself between Agatha, Cadance and Ember and then she said "She's not his lioness anymore! Let her speak up and explain to you two about what happened to her recently that caused her to leave and run away from that inexcusable ruffian and from all of his evil friends! Please, listen to her!".

When Cadance and Ember both heard what Rarity just said, they both said "Fine!", and then Cadance said alone "Now you speak up and tell us everything that happened to you that we need to know!", and then Agatha said back "As you both wish, you're adored majesties." and then she started telling and explaining about what happened to her that caused her to angrily leave Yigal and the other villains and never return back to them ever since, but even after she told and explained everything to Cadance and Ember (and also in front of everyone else), the two female equestrian rulers appeared unimpressed and it also appeared like they didn't seem to believe in anything Agatha told them.

Then, Cadance hissed and said to Agatha "Well that's a very entertaining story, Yigal's lioness, but unfortunately, you had to worry about that little important thing called 'evidence'.", and then Ember added "That's right, if you said you have reformed and turned on Yigal like you said you did, then neither of us believe you! And I suggest that everyone else should also agree with the both of us!", and then the two said to her together and in unison "Face it, Agatha! You was and you still ARE evil! And that's exactly what you'll always BE!", but then Agatha begged and said "No, please! Wait!", but then Cadance and Ember both stepped forward and gave the white lioness angry and threatening looks as neither seemed to believe in her or in whatever she says about herself being good from now on, and then they both yelled at her together at the top of their lungs "GET OUT OF HERE NOW, YOU MONSTER!", thus shocking and even scaring Agatha, who in response stepped aback as the Alicorn princess and the dragon lord both kept approaching her and they also kept gaining on her as she fearfully stepped aback from the two female equestrian rulers, who both appeared willing and determined to chase her out of the royal castle and away for good.

However, Sweetie Belle and Spike stepped in between Agatha, Cadance and Ember, and then Sweetie Belle said "Hey, leave her alone! She's a good lioness and I truly like her for who she recently have became!", and then Spike added "You two should show her some love and respect for what she already have been through before she eventually changed!", but instead of listening to what the young Unicorn and dragon both said, Cadance just used her magic to levitate and forcefully move them out of the way so they won't interfere and won't stop what she and Ember have planned to do with Agatha.

Then, Cadance said to Agatha "Now you're going to get what you really deserve for all of your crimes, you monster!", and then Ember added "That will show you what happens when someone dares to mess up with us and tries to cause so much trouble to our entire world!", and then they both raised up a forehoof and a claw of each of theirs, before they both moved them down together and brought them across both sides of Agatha's face, thus striking together a double slap across her face, causing her to cry in pain and then shake off the pain from the attack, and then she yelled back at them "Stop it, please!", but Cadance and Ember both appeared to be not listening and they kept ignoring whatever she said, before they continued to attack her again and again in order to chase her out of the royal castle, for they both haven't forgotten about all the crimes she already have done before she betrayed and ran away from Yigal and from the other villains and left them all for good.

However, when Agatha couldn't take anymore pain from the Alicorn princess and from the dragon lord's attacks, she fought back in order to stand her ground (which she should've done before when Yigal attacked her in order to get her feeding bowl away from her and back to baby Dan), but then the fight between them stopped when Agatha accidentally ended up scratching and slashing both Cadance and Ember on the chests, thus causing the two to cry in pain as they then held onto their own chests with their hooves and claws before they both turned back to Agatha and looked at her again with angry eyes and their brows furrowed in anger, but Agatha was in fact the one who really suffered the most.

Then, Agatha yelled in pain "I guess that's it! If these two so called majesties still thinks that I'm still evil and dares to attack and harass me just because of my horrible past, then maybe I should just go away and leave you all alone and will not return until I feel like it's safe for me to come back!", but then Rarity begged "Agatha, please, don't go!", but then Agatha turned and tried to give her a reassuring smile and said "It's okay, Rarity. It's for the best. Trust me.", before she then slowly turned around and started to walk away from everyone else and then she left the throne room, but once she exited and left the royal castle, Agatha started to run away with tears forming and rolling down her eyes and trailing behind her as she continued to run, and eventually she left Canterlot, but she didn't returned back to Ponyville, but went all the way to the green meadows near the Everfree Forest to have some time alone with herself so she can let go of her pain.

After everyone watched Agatha leaving in pain and in tears, Cadance and Ember both gave a proud smirk at what they have just done, but then Rarity approached them and then she said to them "Cadance, Ember, for being among the rulers of Equestria, how could you two do this to Agatha?! She means no harm no more! Why don't you believe anything she says?", but then Cadance said back to her "Because she meant nothing but trouble to all of us and to all of our world, and her owners even dumped both Shujaa and Kenai behind them and replaced them with a pure black giraffe and a golden zebra!", and then Ember added "We just want to say that that evil lioness finally got what she really deserved - to be chased away from Equestria, and that's all!".

However, Sweetie Belle and Spike both stepped forward as well and then they both angrily yelled up at Cadance and at Ember right in the faces, starting with Sweetie Belle yelling "You two don't even know her now, but you'll get to know her once you both finally give her a chance!", and then Spike added "Now look what you've done to Agatha - she ran away in pain and in tears! How can you two be still happy with that?!", but then Cadance said back and warned "You two shall watch your tongues when you're speaking to rulers like us like that!", and then Ember added "She had her chance to serve as Yigal's evil lioness - and she failed! Now she got just what she deserves for the rest of her life - to be all alone!".

However, before the argument can continue and go any further, everyone suddenly heard some babies crying, and at first, they all thought it was Kayden and Tallulah who are both crying because they may be hungry or thirsty, but when they all looked at them, they saw that they're not the ones who are crying, but then they pointed and motioned towards both Simba and Sirga the baby Liontaurs, who are in fact the ones who are really crying, and when Rarity saw the two precious baby Liontaurs crying, she trotted up to them and then she tried to comfort them and calm them down, but then she realized the real reason to why they're both crying - Simba and Sirga want their adoptive and surrogate mother (Agatha) back, as they both missed her so much.

When everyone realized what mistake Cadance and Ember just did that caused the baby Liontaurs to cry, Celestia spoke up and said "You have to find Agatha and bring her back!", and then Luna added "She's these precious baby Liontaurs' adoptive and surrogate mother, and they love her so much that watching her leaving in pain caused them both to cry like this!", and so Celestia and Luna tasked every creature to go and find Agatha and take and bring her back home, and they also tasked Cadance and Ember to apologize to Agatha for their cruel actions and for mistakenly believing that she's still evil once they find her, but when the two female equestrian rulers heard what Celestia and Luna said, Cadance begged and tried to say "But we don't want to!", but Celestia and Luna both looked down at her and at Ember with stern looks on their faces, and when Cadance and Ember knew that they don't really have much of a choice but to go with everyone else to search and look for Agatha, they looked at each other for a moment and then Cadance said to her and asked "You think what I'm thinking?", and then Ember said back "Yeah, I do. It's our fault that Agatha ran away in pain and in tears like this.", and then Rarity approached the both of them and then she said "And you two are going to help us all find her and bring her back home, and of course, you two have no choice but to apologize to her for what you both did to her, which resulted in and caused her to run away like this!", and so Celestia and Luna bid temporal farewell to everyone else and said that both will wait for them all until they come back and return with Agatha, and so Chloe, Aylene, Stephan, Tah, the mane seven, the CMC, Spike, Shujaa, Kenai, Bluebell, Zach, Layla, Aron, Linda, and Trog and all the other babies and toddlers (including Simba and Sirga the baby Liontaurs) all left the royal castle and embarked on a long journey to search for Agatha, and Shining Armor, Cadance, Flurry Heart and Ember also (reluctantly) followed them all close behind.
