Jack swam further out into the ocean, readying himself to face the oncoming storm. This is for Hiccup. "Bring it on, Pitch! Come and get me!"

"Well, what an interesting development. The gallant prince has come to rescue his kin." Tooth swam out from the shadows. "Hi, Jack."

"Tooth?" Jack stared at her in shock.

"Not quite." Shadows enveloped her, revealing the Sea Witch. "Always the hero, Jack."

"So this was all a trick?! To get me to reveal myself and become your slave!"

"And how easily you fell for it. Now Santoff Clausen will crumble, and so will Berk."

Jack's eyes burned white with magic. "I'd like to see you try."

"Who's going to stop me? Your little lover boy? He's trying to drown himself as we speak."

"You can't fool me again, Pitch. Every word out of your mouth is a lie! You'll pay for what you've done!" Jack let loose a shock of power, sending a blast of ice towards Pitch's heart.

Pitch ducked with a laugh. "Silly boy! What fun you are!" He waved his hand, a misty bubble forming in the air. "Look if you don't believe me." In the bubble played the image of Hiccup searching in the water for Jack. "He can't breathe, Jack. He'll die."

"I won't fall for your tricks again," he ground out. "You fooled me with the cuff but I know Hiccup. He's the most stubborn creature I've ever met. He wouldn't do that."

"But how can you be sure? He's such a lovesick little guppy, and he did say he would rather drown than be without you."

"I'll just have to trust him!" Ice shot up around the witch, trapping him inside.

"Trust. How easily breakable trust is. How can you trust you, Jack? You lied to him; you've left again; you abandoned him just when he opened his heart to you. What is trust when one side is a liar?"

"Shut up! You know nothing about love. You don't get to lecture me on it!" Jack started to condense his icy cage, trying to crush Pitch inside.

"He's dying, Jack. And it's all your fault." Pitch's laughter rang out around Jack as the ice exploded. "I always win, Jack. Don't forget that," the voice whispered, fading.

A sense of dread filled his stomach. "Hiccup." Jack swam as fast as he could back to the shore. He looked around desperately beneath the crashing waves for any sign of his viking. There! At the sight of a familiar metal glint, Jack darted forward and dragged Hiccup to the surface again. He pulled the rider onto the sand. "No no no no. Why would you do that?" He breathed into Hiccup's mouth, trying to force the water from his lungs. "Don't leave me!" Hiccup lay there, motionless, his lips blue. Jack sobbed against his chest. "This wasn't supposed to happen. We were supposed to live happily ever after. I never should have dragged you into this, Hiccup. I'm so sorry."

Laughter rang out through the air as the storm grew worse. Santoff Claussen is mine! And soon, Berk will be mine too!

Jack looked wistfully down at his love and stroking his cheek. He started to sing softly, weaving into the tune the magic of an ancient siren spell he'd seen before:

"If there could be another day not asking for too much,

but another day I see your face or if I could feel your touch.

Only you create this feeling in me I hope you understand

just the sight of you and I do believe that you will always be my man.

And I can't help but think that if I didn't have you that I wouldn't be where I am, you give me words of wisdom, advice that's wise and you tell me that I can.

For we are two hearts coming together,

joined as one from now until forever."

He let out a gasp when he felt the magic doing its job. Jack whispered over Hiccup's lips, his own almost touching. "I bind my life to yours. If you die, I die with you. If you live, I live. I share my life with you."

Green eyes slwly opened. "Let me come with you, Jack," Hiccup whispered before closing the distance between their lips. "We belong to each other, remember?"

"Hiccup!" Jack cried in relief and threw his arms around him. "I love you!" He kissed him again and again.

Hiccup smiled and held Jack close. "I love you, no matter who you are."

Jack returned his smile. "Promise you won't do something so stupid again. You could have died, Hiccup. What if I hadn't gotten to you in time?"

"I don't know what happened. It felt like something was pulling me down."

"Pitch," he growled. "He's still here...Look out!" Jack pushed Hiccup roughly, the two of them rolling out of the way of a shadowed spear. "Go! You need to get to Toothless!"

"Be careful, Jack!"

"You too!" The prince slid back into the water, hoping to draw Pitch's fire from the rider. "What do you want, Pitch!? What was the price that you so desperately want me to pay?" Jack brought up a sheet of ice in time to protect himself from another shot.

"I want the world, Jack. With your death, I'll claim Santoff Claussen. I'll save Berk for later, as a favor."

"My father will never bow to you!"

"I know. But he will bow to you."

"What's that supposed to mean?" Jack dodged or blocked each attack, sending blasts of ice when he could.

"As we speak, your father is giving you the crown. Well, he's giving me the crown."

"He wouldn't give me the crown. My brothers are meant to take over the throne."

"Oh, but what a father wouldn't do to have his favorite son back."

Jack launched himself at the witch, filled with rage. "I won't let you get away with this!"

"You think you have a choice?!" Pitch laughed, and his shadows wrapped around Jack tightly. When they slithered away, Jack's body was shriveled and brown from the waist down. "Wouldn't do to hurt that pretty face, would it? Might need it for later."

The prince screamed in pain, writhing in the water when he found he could barely stay afloat. Jack couldn't do anything when he was flung from the sea and sent crashing through his own ice. When his body stopped bouncing across the sand, he groaned. A flicker of hope washed through him when he saw his staff on the sand nearby. Maybe, just maybe, if he could get his legs back he could keep fighting. Jack slowly dragged himself across the sand, desperately trying to reach for the wood.

Toothless swooped down onto the beach, and Hiccup practically leapt off his back when they landed. "Jack! Oh sweet Odin, what has he done to you?" He picked Jack up, careful with his shriveled flesh. "What do you need?"

"S-staff," he gasped out, pointing towards it. "If I had legs again…"

Hiccup grabbed Jack's staff and placed it in his hand. "Go, my love. Defeat him."

Jack lowered himself down to his feet carefully. They were weaker than before but at least he could move better than with his tail. "I don't know if I can, Hiccup. I was never a warrior like my brothers."

"You have Swiftide, and you have me."

"Thank you." He gave Hiccup tight hug before running off towards Swiftide's cave. The dragon happily let him on her back and took to the sky. "Pitch!" he screamed, pointing the staff threateningly at him. "Leave my family alone!"

"Or what, you pathetic whelp? You'll ice me?" Pitch laughed. "Why don't you just give up? Take your human boy and go?"

"And leave you to run rampant destroying everything I love? In your dreams!"

"You can't have it all, Jack. Choose your home, and I destroy Berk. Choose Berk, and I destroy Santoff Claussen. Now's the time, Jack. You chose once before, and you can do it again."

"I won't choose! Maybe I'm cursed to never be completely happy in the sea or the sky. But I can't make that choice anymore. I love both equally, and so I choose to put an end to this!" Jack leapt of Swiftide's back, hurdling towards Pitch with gaining speed. "I choose happiness!" He collided with the witch with an impact of magic so strong it froze the sea's surface everywhere in a mile radius.

Pitch grunted with the force and pushed Jack back with a roar. "I refuse to lose to you!" He shot his shadows towards Jack, grabbing the staff from his hands. "What I give, I can take away." He closed his fist, and the shadows shattered the staff into pieces. "If you won't choose, I'll do it for you. May you never again see your precious human! May the sea forever keep you apart! May the waves carry you ever further away!"

"No!" Jack cried out when the staff broke, clutching his chest as pain shot through him. He was left to lie sobbing on the ice, his tail flopping around uselessly. Jack watched in horror when Pitch pulled a glowing golden scepter from the ice. Swiftide swooped down to shield him from the witch. "Hiccup! Be careful! With that scepter he can control all the powers of the seven seas."

"What?" Hiccup gasped, his body knocked from Toothless' back onto the ice. He groaned, giving Jack a look. "Where in Odin's name did he get that?!"

"My father, King North of the Seven Seas. He tricked him, posing as me so my father would crown him King and give him the scepter!"

"You're a prince?!" Hiccup gasped, leaping out of the way as the shadows shot at him. "So I was right!"

"I really don't think-" He paused to throw up an ice barrier around them. "That right now is the time to be discussing this!"

"Now is the perfect time! You lied to me!"

"What did you expect me to say when you asked why I was on that ice? Oh, I'm the son of the most powerful magical being on this planet but I gave it all up to fly and to be with you?!"

"That would be a start!" Hiccup ducked another shadowy spear.

"Few people in the world even know we exist. It's forbidden to reveal ourselves!"

"And?! It's not like I'm just anybody!"

"I hardly knew you yet!"

"And when you did? Maybe after we slept together?!"

"Revealing the secret would mean I had to leave! I couldn't do that! Watch it!" Jack knocked Hiccup over to get him out of the way of another attack. "I'm sorry, okay?! I was selfish, and I didn't want to give you up!"

Hiccup reached over and pulled Jack into his arms. "No matter what happens, your secrets are mine. Tell me everything," he whispered, kissing Jack quickly before pushing him back. "Take Swiftide and go save your family! I'll take Toothless and see what I can do for mine!"

"I won't leave you!"

"Jack, we come from different worlds, and both of those worlds are in danger." He kissed him again. "If I don't save Berk, where will you come home to?"

Blue eyes locked with green. "Be safe. You are my home, Hiccup. Make sure you're still here to come back to."

"I will. We have so much left to explore, remember? A whole world."

Jack reluctantly pulled himself onto Swiftide's back, holding tightly to her neck. "Let's go, girl." The scauldron dove through a crack in the ice and disappeared into the depths.

Hiccup looked around at his burning village, devastated. A loud roar made him turn, and he froze. "Alpha…"

Santoff Clausen was a mess of chaos. Pitch had rallied all of the predators in the vicinity to his cause. Merfolk bewitched by him fought against their own friends and family. "Dad!" Jack and Swiftide ducked through the insanity until they came to the palace. He looked down to see the king and his brothers fighting in the courtyard. North's swords were a flurry of power, taking down any enemy in his path. "Dad, look out!" Jack shot a sheet of ice in time to save him from the bewitched merman trying to attack him from behind.

"Jack!" Tooth darted towards him, pushing against his chest. "What's happening?"

"Pitch has completely lost it. He's attacking Berk and here at the same time. He has Dad's scepter up on the surface."

North gathered his son into his arms. "My boy! Where have you been?!"

"Dad!" Jack hugged his father tightly. "It was all a set up. Pitch just wanted you to give him your scepter so he could be the most powerful being in the world."

"I know, Jack. As soon as he had it in his hand he revealed everything and attacked. But you are back now, and you can help!"

"I can barely swim. I won't be much help." As soon as North let him go, he settled onto the ground without his aid.

"What happened to you?" The king took in his son's injuries.

"It was Pitch. I don't know what he did, but it's not the same as it used to be." Jack looked down, ashamed he'd let Pitch get the better of him. "I'm sorry, Dad. I failed you again."

"I can help you, Jack! You can hold my fin, and I'll take you anywhere!" The orca settled under his arm.

"Tooth, are you sure? It's dangerous out there."

"I can help! Let me help!"

"Then let's do it. Can you take me around the perimeter?"

Tooth nodded. "I can do that! I'm good at being sneaky!"

"We can do this!" Jack held onto his friend's dorsal fin. The two swam out of the palace.

"What's your plan, Jack?"

"Freeze any enemies we can. They aren't themselves right now and can't control what they do. And if we can get through all that, try to make a barrier." Jack peeked around a corner to see what they were facing.

"Jack, is your two-leg okay?"

"I hope so."

"I hope everyone else is going to be okay too."

"We'll just have to do our best and see them on the other side of all this."

Hiccup's eyes scanned the ice-filled water from the sky. "He's down there somewhere, Dad. He's doing bad things if the Alpha has awoken."

Stoic looked to his son. "What do you want us to do? We'll follow your orders, son."

"I need to somehow send a message to Jack. He needs to know what's coming."

"Any ideas? There's a thousands of feet of water between you and him. "

"I know that!" Hiccup sighed and scratched the back of his head. "I don't even know where to find him."

"Do you trust he can handle himself down there?"

"I know him, and I know he can do anything. I'm just worried about him. You couldn't help worrying about Mom."

"You're right.I couldn't help it. But she would have roasted my behind had she known I was worrying over her when I should have been focusing on battle. I think your Jack would do the same."

"I don't doubt it. He is the bravest man I've ever met. Dad...I do love him."

"Then show him by winning this fight."

"I won't win this. We will. All of us."

"Lead the way, son."

Jack collapsed back against a castle wall, chest heaving. "I think...I got them all."

Tooth clicked. "Jack, are we winning?"

"Down here. I don't know if it's the same up on the surface."

"Should we check?"

"I want you to stay here, Tooth."

"But I can help you!"

"It's too dangerous up there. Pitch has the scepter and is more than likely causing a lot of harm. I don't want you to get hurt. Stay here." Jack gave her a comforting hug.

"Be careful, Jack."
