Lucky stopped talking, then Lily was signalling him to talk. "I.... Dont..." he finally replied, gasps and whispers were heard, Lucky got frustrated inside that he raged and bursted out the things he wanted to say "Go on! Whisper and think that the thing I'm doing is not princ-likely! You may be wondering, why even marry her if at the end you will just say no? It was'nt my fault, I got distracted so I accidentally said yes, then this girl beside me did not even bother ask back if she didnt understand! Also, my brother listened to a girl that is not his siblings , and did not bother asking me the question Really? Are those all true?! But you know what he said? He said I'm so proud of you! And walks away! What kind of big brother is he?! He did not even notice that I was already frowning at the very start when I heard him and the King's conversation. Go! Complain that it's my fault I wasted all of your time"he said, then one of the merfolk sitting stood and asked "I know noone would get upset if they dont love anyone yet, but you my highness... You seem upset! Who is this girl you love and if she's here, can you by chance show her to us?"then Lucky's face went blank for a moment then, he slowly smiled "Ofcourse"he answered. He approached Cathy, then Cathy's eyes opened wide, "W-wah? B-but Lucky, they know I'm Princess Cathy of Crystaux!"she whispered to him, "Don't worry, if they shutted you down, remember. I'm here to protect you"he whispered back, Cathy sighed and said "Let's do this" as she stood up from her seat. "Feast your eyes, this is Cathy my love..."as he scratched his neck, everyone gasped, whispered and murmured things. "Isnt that Philip's sister?!"Paul raged as he went to Lucky's face, Lucky putted Cathy behind him and spoke "Yes, and what's wrong with it?". Then Paul replied "Have you forgot mermaid ryle 1730?! Never talk to humans ever again! I thought you and your siblings inclunderstood never to make communicate ewith humans ever again! Did you see what they did to mom and dad Lucky?! Are you now against us?!"then Katelyn stood up from her seat and said "That's where you're wrong dear brother... Not all humans are destructive and would harm us! And I saw that it was that orange haired human's fault. Please dont include those who are innocent!". Paul's face went blank, "You two, leave this Kingdom at once! Take this human friend of yours too!"he demanded as the three left Goldtina. On the way there "Ummm... What's your name, Katelyn right? I uh... Was wondering, why did you defend me and Lucky?", then Katelyn suddenly turned red "Er... I-it's because, he's my brother! And I think, not all humans are evil. I know the orange haired guy killed our parents, but my brother should'nt include the innocents!"she sighed and apologized for what Paul have said. Cathy accepted it, she smiled and hugged her, "Um brother? What in sea shakes is she doing?"Katelyn asked. His brother laughed lightly "It's called a hug Katelyn. It can show someone that you appreciate something, you're happy, or um... Showing affectionate?"he said. Then Cathy offered them to stay at her place until they are ready to go back. When they reached there, she said "Stay here, I'll get a friend of mine to turn both of you into mermaids so you can stay at my secret room"as the 2 waited at the wave that lifted them up. After almost 30 minutes, Cathy has returned with her apprentice and her apprentice's gf. "Okay you two, wear these crystals. I putted laces so it can be necklaces, so you don't have to put it in your pockets and loose it!. Just think that you want to turn into a human and, you will turn into one! That's the crystal I gave to Cathy, only she has light blue crystal, and you guys have yello and pink. Go on, try it!"she said, as both Lucky and Katelyn followed Ducky's instruction and they turned to humans! But, when they turned into one, they had nice clothes!
This is Katelyn's clothing:
