When the next day arrived, Stephan and the Zebrataurs (minus Timmy and Layla) went out of their cave to have some fun together, and it was also the fourth and last which will help Brandon determine if Stephan should become an official member of the Zebrataurs herd (because Stephan only became a honorary member of the herd, during the second day).

As for Timmy and as for his older sister Layla, they went along with Chloe, Aylene, Bluebell and everyone else to search for Stephan and the herd, find them and persuade Stephan to come back home to Ponyville. While searching for Stephan, Fluttershy said "I hope Stephan will listen to us.", but then Rainbow Dash said "His father is such an unforgivable jerk for fooling him and lying to him about all of us not being his friends all along!", and then Rarity added "I hope that ruffian will be eventually caught and sentenced to live in Tartarus next to Lord Tirek and Cozy Glow for the rest of his life!", and then Bluebell said to them "I want Stephan to know that I love him with all my heart, and I also want him to know that he deserves to have me as his future wife instead of some Zebratauress who might be too unfit for him to be with.", and then Layla said unoffended as she understood Bluebell is not specifically referring to her "I understand you, Bluebell. I don't want to be Stephan's future wife, and I don't want him to have a Zebratauress like any other female from Brandon's herd as his future wife either.", and then Aron said "Brandon is trying to trick Stephan into becoming evil just like his father." and then he added "When I get my hands on that evil Zebrataur's neck, I'm going to strangle him for twisting Stephan into becoming evil against his will!".

However, then Linda said to him "Strangling that Brandon still won't help persuading Stephan to see that Zebrataur was been lying to him from the start. We need to find the best and most perfect way that will help us show Stephan that Brandon is merely just using him against himself.", and then Applejack said "I have to agree with Linda. We must find a way to persuade Stephan to see and realize that no good Zebrataur varmint is trying to make him evil just like his no good father.", and then Starlight added "I hope Stephan is alright. He needs to know that he could not trust Brandon.", and then Twilight said as they all kept searching for Stephan and the herd "I would like to show that monster for a Zebrataur some real magic for turning Stephan into a ferocious beast!".

Meanwhile, Stephan and the Zebrataurs herd were all doing fine together, but that is until the same adult female southern white rhinoceros from before suddenly appeared and started to approach them all with an evil look on her eyes as she also gave Stephan and the Zebrataurs an evil smirk. However, when one of the Zebrataurs, a male (not Brandon or Biff), saw the female white rhinoceros approaching towards them (Stephan, the herd and himself), he screamed "Run! A white rhinoceros is coming towards us!", and when Stephan, Brandon, Biff and the others also turned and saw the female white rhinoceros approaching towards them all with an evil smirk on her face, this is when Brandon cried "Everyone, run!" and so he, Stephan and the others all started to trot and gallop and they all tried to escape, before the female white rhinoceros then started to chase after them in a fast burst of speed so she can catch up with one of them, separate him or her from the rest of the herd, and then kill him or her for pleasure.

Stephan tried to gallop as fast as he can to keep up with the Zebrataurs herd, but then he started to tire off and slow down, thus allowing the female white rhinoceros to catch up with him and separate him from the Zebrataurs herd. Then, the female white rhinoceros said to Stephan in a gruff and evil voice as she gave him an evil smirk "Now what do we have here? Isn't it a normal white centaur? What are you doing with a herd of Zebrataurs?", but then Stephan said to her "Please, leave me alone! I did nothing bad to you before! Let me go back to my herd!", but then the female white rhinoceros stomped her right foreleg and foot on the ground next to him and yelled "Silence!", and then she added evilly "If you want to be with your herd again, you will need to serve for me as my assistant, centaur. If you want to be still alive, you will have to obey me. Only me. Only Ganda.".

However, Stephan then said "I serve and obey my leader Brandon, and not some heartless beast like you!", but this only made Ganda (the adult female southern white rhinoceros) angry at him before she said with rage rising in her eyes "You WILL obey me, and I know you DO want to be mine!", and then she pushed him and managed to knock him off his hooves and caused him to hit the ground, before she then aimed her head and horns at Stephan's upper human back and added "If you won't obey me, centaur, then you will die!", and then she angrily yelled "ON MY HORNS!", but before she can strike at Stephan's upper human back, a familiar female voice suddenly called and yelled "Leave Stephan alone!", and when Ganda heard the female voice that just yelled at her, she then got away from Stephan and yelled back "Who goes there?!", and then Chloe, Aylene, Bluebell, Andy, Zoey, Timmy, Layla and all the others came towards her and Stephan and then they all stopped a few yards away from them.

Then, Bluebell cried "Leave my dear Stephan alone, you big ugly rhinoceros!", but this only angered Ganda before she then yelled back "Who are you calling a big ugly rhinoceros, you trump!", but then Chloe cried "You leave Stephan alone!", and then Aylene added "Yeah! Just turn around and go away!", but then Ganda yelled "That's what you all think!" before she then charged towards them, but then Bluebell and Layla also went towards her, and then the three all started to fight each other in a fight of two against one, and so Bluebell and Layla worked together to fight Ganda and defeat her before they will go to Stephan and persuade him to come back home to Ponyville.

Then, Bluebell and Layla started to kick together at Ganda's back with their horse and zebra legs and hooves, and this caused the white rhinoceros to growl and cry in pain and she tried to shake them off, back then Layla jumped off her back while Bluebell just flew up by using her wings to do so, and then the two went up to Ganda's front and then they both turned tails and bucked her with hind horse and zebra legs on both sides of her face, thus causing her to growl and cry in pain some more before she then decided to retreat away for her life, and so she then started to run away for her life, thus leaving everyone alone with Stephan, who barely just managed to get back up on his hooves.

Then, Bluebell, Layla and everyone else approached Stephan and they were all happy to see him again, but Stephan wasn't feeling the same way before he simply asked as he turned away from all of them "Oh, what are you all doing here?", and then Bluebell answered and explained "We all came here to search and look for you, Stephan.", and then she went up to him and kindly grabbed and held at his hand with her own and then she begged and added "Please, come back home with all of us, Stephan. We all really miss you.", but then Stephan smacked her hand away from his own hand using his other hand and then he turned to her and yelled at her "Go away from me and stay away from me, Bluebell! I don't love you anymore! You're a disgrace to all of centaur kind! My father was right about you! You're indeed a dumb loser for the good centauress you are!".

When everyone heard what Stephan just said to Bluebell, they all gasped in shock while Bluebell looked at Stephan in disbelief and then she asked him "Why are you saying this to me?", but then Stephan looked at her unpleasantly before he yelled at her "Shut up, good centauress! My father told me you're such a dumb loser for who you are!", and this made Bluebell gasp in shock when she heard Stephan calling her a dumb loser for the second time, and then she asked him "Stephan, what are you talking about? I'm not a dumb loser. Why are you saying this to me?", but then Stephan said to her "I give you a fair warning, Bluebell! From now on, I'm part of Brandon's herd, and since he talked to my father about that before, he (Brandon) accepted letting me become a member of his herd, and therefore - nobody loves or likes me no more, except for Brandon and his herd!".

However, when everyone heard what he just said, Layla then also came forward to help Bluebell persuade Stephan to come back home to Ponyville and then she said "If you think Brandon really liked you so much like you at least expected, then I have something to say and tell you and to everyone else about him.", and then she yelled and let out the answer "Brandon is evil! He never even liked you! All he cares about so much it's for only himself!", and then Bluebell added in agreement with Layla "Layla is right! If Brandon dared to banish her and her little brother from his own herd for no reason at all, then he might do the same thing with you when you're at least expected!" but then Stephan yelled at the both of them "Shut up your mouths! Both of you!", thus shocking the kind centauress, kind Zebratauress, and also everyone else who stood behind them.

Then, Stephan said and added with tears starting to form in his eyes "Well, you all know what?! I'm not anymore friends or allies with any of you no more! News flash - none of you are no longer my friends or allies, and I'm from now on nothing more but your enemy! Goodbye forever, everyone!", and then he turned away from everyone and he was about to leave, but then Bluebell tried to place her hand on his shoulder and she cried and begged "Please, Stephan! Don't go! I love you with all my heart! Don't leave me!", but then Stephan smacked her hand away from his shoulder and then he yelled "Lair! You don't really love me! How could a good centauress like you love a bad centaur like me?! I'm done with you!", but then Bluebell cried "Stephan, you're not evil! Brandon and your father were both just tricking you into becoming evil!", but then Stephan yelled "I don't even care about what you're even saying anymore! Brandon is now my leader and I must obey him and follow his orders!", but then Bluebell cried "Stephan, you can't mean it!", but then Stephan finished and yelled "Goodbye, Bluebell!" and then he started to gallop away from Bluebell, Layla and everyone else with tears rolling down his eyes and trailing behind him, and when Bluebell saw him leaving, the heartbroken centauress lowered down onto her horse haunches and then she finally burst into tears and started to cry, thus prompting Layla and everyone else to come and comfort her and try to calm her down, but then Layla turned and looked in the direction where Stephan went and then she said with rage burning in her eyes "Brandon, you will pay for what you've done to Stephan! When my friends and I will find you, we'll be all giving you a taste of your own medicine! You twisted Stephan and you also turned him evil! You will pay for what you've done!".

As for Stephan, he kept galloping away until he felt he was far enough from all of his 'former friends', and this is where he finally slowed down but kept walking in a normal walking speed, but after a while, Stephan finally stopped dead in his tracks and then he said "Who needs Bluebell? Well, not me!", and then he added "She can find some other kind and yet stupid centaur she can choose as a future husband or something like that and forget about me!", but then a male voice said evilly "Stephan, I'm so proud of you!", and when Stephan heard the voice, he turned to see Brandon coming towards him, and when Brandon ended up stopping right in front of him, Stephan asked the Zebrataur leader "Brandon, what are you doing here?", and then Brandon said "Well, I'm just looking for you, that's all.", and then he added "What you did back there was just the same thing I would've done if someone would dare to betray me and my herd!".

When Stephan heard what Brandon just said, the centaur then asked "Really?", and then Brandon said "Exactly! The way you yelled at both that centauress with the wings and that traitor Layla is just what I wanted to see in you! That just showed me you're indeed fit and good enough to be one of my herd!", and this made Stephan ask "Are you telling me the truth?", and then Brandon said "Yeah, that's right, Stephan! You passed the test of proving me that you're fit and good enough to be part of my herd within four days! From now on, you're not only a honorary member, because now you're also an official member of my herd!", and then he placed a hand on Stephan's shoulder and added "Welcome to my herd, Stephan! Now you're in!".

Just then, Biff came out of nowhere and appeared behind Stephan, and then he said to him "Come, Stephan. You have so much more to do with us.", and then he went to Stephan's side and placed a muscular human arm and hand behind the centaur's upper human back and then he added "The herd is waiting for us. Come with us, Stephan.", and then he started to push and lead Stephan from behind while Brandon turned tail and started to lead them from the front, and then the three started to walk away and all the way back to the cave, where all the rest of the herd were all waiting for them to come back.

When Brandon and Biff returned back to the cave with Stephan, the Zebrataurs greeted and welcomed the three back, and this is when Brandon and Biff declared and announced that Stephan is now an official member of the herd, much to the herd's sudden outburst of joy and happiness to know that they all finally have Stephan as the first official member of the herd who is not a Zebrataur like the rest of the herd, and this made Stephan to burst into tears of joy as well, before Brandon and Biff then hugged him and tried to calm him down, and when nighttime came, Stephan and the herd fell asleep peacefully inside their cave, and Stephan was happy because he thought he finally found just the right place where he really belongs, but what he still don't know is that his joy and happiness won't be lasting this very long.
