After having fun together, Sonic and Adagio are trying to find Vampirina to tell her about their engagement. When they found her, Sonic called her "Vee! Um... excuse me, queen; I want you to meet Princess Adagio from the Southern Islands" Sonic said introducing Adagio "Hi your majesty" Adagio said "And we want... your blessing... for our wedding" Sonic and Adagio said by the same time "Um... wedding?" Vee asked "Yes Vee!" Sonic said by exciment "Sorry, I'm confused" Vampirina said "Well we still didn't planned anything; the food, the clothes, everything and... wait! Can we live here?" Sonic said "Here?!" Vee asked nerviouslly "Absolutelly!" Adagio said "We can invite your 12 silbings to live here too and..." Sonic said but his sister interrupt him "Wait Sonic, you can't! No silbings will stay here and no one will have a wedding" "Wait, what?" Sonic asked "Can I talk to you brother... alone?" Vampirina said "No! Whatever you want to say, the both of us will listen to you" Sonic said "Okay... you can't fall in love too soon" Vee said "Yes I can, when is true love!" Sonic said "Sonic, what do you know about true love?" "Well... more than you! You only ignore other people!" Sonic said and Vee said offended "You asked for my blessing, but the answer is no. Now... excuse me" "Um... your majesty, maybe I can..." Adagio said, but Vampirina stopped her "You can't, and... I want you to retire" Vampirina then said to a guard "The party is over, close the gates" But... "Vee, wait!" Sonic stopped her and he take out one of her gloves "Give me back my glove!!" Vampirina yelled "Vee please... please, I don't want to live like this anymore" Sonic said "Then... leave!" Vee said to her brother and she started to walk away, but Sonic still was arguing with her "I have done something to you?!" "Stop it Sonic!" "No! Why do you ignore me, why do you ignore everyone, why are you scared of saying it?!". Vampirina can't take more yellings from her brother that... "I said... enough!!!" Vee yelled and she thew a ray at the hall, making ice spikes between she and the guests; since her brother get her glove, she has unleashed her snow powers. Everyone was shocked, especially Sonic and Adagio "It's sorcery! I knew something was going on here" Trixie said "Vee..." Sonic said shocked and Vampirina started to run, all of the guests from outside cheered at her, untill she touched a fountain and freeze it. Behind her, Trixie and her sidekicks were chasing her "There she is, catch her!" Trixie yelled "No! Don't go close to me!" Vee said and she accidentally shot a ray to Trixie and her girls "M-monster!" Trixie yelled at Vampirina and she started to run away from the castle, but... her brother and his girlfriend were chasing her too "Vampirina!" Sonic called, but she kept running away. Vampirina then arrived to the edge of the fjord, when she stepped in the water, she saw that she can pass to the river freezing it; then she noticed that her brother was coming "No! Wait!" Sonic called, and his sister started to run though the water "Vee! Wait!" Sonic shouted and he slipped on the ice "Sonic!" Adagio said worried, and Sonic for bad luck, he didn't get his sister.
Meanwhile, in the outside of the castle... it was snowing! Sonic was surprised about the snow his sister make "Are you okay?" Adagio asked "No" Sonic answered "Did you knewed about this?" "No" and Trixie was really angry about this "Oh no! It's... snow! The queen make a spell on the kingdom! We have to stop her" Trixie said angrilly "No, wait!" Sonic yelled "You?! You have powers too?! Are you a monster too?!" Trixie asked "No, I don't have powers!" Sonic said "No, he doesn't have!" Adagio said "And my sister is not a monster!" "She tried to attack me!" "You slipped in the ice!" "HER ice!" And Sonic interrupted "It was an accident, she get... scared, Vee is not evil and she would never do that. It was my fault by making her angry, and I will be the one to look for her" "Wait Sonic! It's dangerous!" Adagio said "Vee is not that, when I find her, I will remend this" Sonic said "Adagio, you stay here and take care of Arendelle" "Sure Sonic" Adagio said "I leave Princess Adagio in charge of the castle!" Sonic said to the people "Are you sure you trust her? I don't want her to hurt you" Adagio said worried "Is my sister Adagio, she won't hurt me" and Sonic ride his horse to the forest
Meanwhile, Vampirina was in the mountain walking away from the kingdom and she then started to sing

Vampirina: 🎵The snow glows white in the mountain tonight🎵
🎵Not a footprint to be seen🎵
🎵A kingdom of isolation🎵
🎵And it looks like I'm the queen🎵
🎵The wind is howling like this swirling storm inside🎵
🎵Couldn't keep them in, heaven knows I've tried🎵
🎵Don't let them in, don't let them see🎵
🎵Be the good girl you always have to be🎵
🎵Conceal, don't feel, don't let them know🎵
🎵Well now they know!🎵
🎵Let it go, let it go🎵
🎵Can't hold it back anymore🎵
🎵Let it go, let it go🎵
🎵Turn away and slam the door!🎵
🎵I don't care🎵
🎵What they're going to say🎵
🎵Let the storm rage on🎵
🎵The cold never bothered me anyway🎵
🎵It's funny how some distance🎵
🎵Makes everything seem small🎵
🎵And the fears that once controlled me🎵
🎵Can't get to me at all!🎵
🎵It's time to see what I can do🎵
🎵To test the limits and break though🎵
🎵No right, no wrong, no rules for me🎵
🎵I'm free!🎵
🎵Let it go, let it go🎵
🎵I am one with the wind and sky🎵
🎵Let it go, let it go🎵
🎵You'll never see me cry🎵
🎵Here I stand🎵
🎵And here I'll stay🎵
🎵Let the storm rage on🎵

Vampirina stood in the top of the mountain and she make a big castle made of ice

🎵My power flurries though the air into the ground🎵
🎵My soul is spiraling in frozen fractals all around🎵
🎵And one thought crystallizes likes an icy blast🎵
🎵I'm never going back🎵
🎵The past is in the past!🎵
🎵Let it go, let it go🎵
🎵And I'll rise like the break of dawn🎵
🎵Let it go, let it go🎵
🎵The perfect girl is gone🎵
🎵Here I stand🎵
🎵In the light of day🎵
🎵Let the storm rage on!🎵
🎵The cold never bothered me anyway🎵

What will happen next?
