At Night, Hiccup freed the dragons from the arena and send them to the cove.
Next day, the warriors returned from the hunt.
Hiccup wrote a letter to his father to say goodbye.
Stoick sighs in stress.
Gobber ask "any luck in finding the nest?"
Stoick answers "not even close. Did you have any luck?"
Gobber comments "well if you consider your child worries are over."
Stoick ask "Hiccup?"
Villagers pat Stoick on the back "no one will miss that old trouble maker. Out with the old. In with the new."
Gobber comments "who would have thought. He has a sway with the beast. He said after he finished his last secret project, that he was leaving Berk for good."
Stoick ask "why would he leave for?"
Gobber sighs "the teens commented that he didn't get eaten by the Gronckle and he snapped."
Stoick command "I want him found right now.
The villagers looked everywhere for Hiccup.
Stoick checked his son's bed room to find a note.
Dear dad,
I decided to leave taking the dragons from the arena. Everyone wanted me thrown into the sea when I was a baby. I trained a Night Fury and together, I plan on ending your dragon raids. I don't plan on coming back for a while.
Berk isn't my home. If you kill anymore dragons, I won't forgive you. Goodbye.
Stoick left his son's bedroom and called off the search.
By night time, everyone ate in the Meade hall.
Stoick comments "Hiccup told me in his letter that he left with the dragons and plans on ending the dragon raids by himself. There will be no more dragon killing until he returns.
His secret project was training a Night Fury to help him escape from here. He said Berk was never his home because of how we treated him."
Two weeks later, Astrid was determined to fix her and Hiccup's relationship.
She snuck inside the forge and searched Hiccup's private room for answers.
She searched through papers to see pages of Night Fury.
She looks at a stack of papers in the corner and checked them to see they were of her with a letter "you were my crush, Astrid. When you dumped me as a friend, I felt that my happiness died with it.
You have a choice between Snotlout, the dumb one who would lead the village into the ground or me after I end the dragon raids. I don't plan on returning for a few years because you all hurt me for fifteen years, making me feel unwanted.
You can read my diary in secret to read how I felt about everyone. Just don't let anyone else read it."
(With Hiccup)
Hiccup comments "okay, guys, let's end the Red Death."
The dragons blast a hole in the nest.
The Red Death broke the rest of the wall to enraged that it I was disturb.
Hiccup and Toothless blast fire at the Red Death until it spread it's wings and flew after them.
Hiccup ask "do you think that did it?"
The Red Death roared, chasing after Hiccup and Toothless.
They lead the Red Death through sea stacks.
The Red Death destroyed the sea stacks like nothing.
Hiccup look behind to see the Red Death chasing them still.
He looks up at the dark clouds and says "okay, Toothless. Time to disappear."
They fly upwards to the dark clouds.
The Red Death follows them into the clouds and lost sight of them.
Toothless made passes while firing shots at the Red Death's wings.
The Red Death roared in pain.
After six shots to it's wings, the Red Death blast fire in all directions.
Hiccup commands "watch out!"
Toothless flew past the fire and caught the prosthetic tail fin on fire.
Hiccup looks behind to see the prosthetic tail fin burning slowly and says "okay, times up."
They fly down towards the ground.
Red Death caught sight of them and followed after them.
Toothless continued flying down towards the ground with the Red Death chasing them.
Red Death begins building up gas in it's throat.
Hiccup commands "hold, Toothless."
Red Death opens it's mouth to blast them.
Hiccup yells "NOW!"
Toothless spins and fires a shot into Red Death's throat causing it to burn on the inside of it's body.
Toothless flew back up the body of the Red Death as the dragon crashed into the ground because it's wings ripped from the holes.
The prosthetic tail fin burned completely and couldn't steer.
Toothless crashed into the club size tail knocking Hiccup unconscious.
The Deadly Nadder flew past grabbing unconscious Hiccup before he falls back inside the flames.
After the flames died, the dragons decided to fly them back to Berk inside the cove.
At Night the dragons arrived carrying Hiccup and Toothless back to Berk.
Toothless jumped out of the cove using it's claws to climb.
He ran to the village and sneak inside and sniff for villagers to a big building.
He push the door open taking everyone's attention.
Warriors stopped eating in shock.
Stoick got up and slowly walked upto the Night Fury and ask "where's my son?"
Toothless lower in get on move.
Stoick climb on Toothless's back.
Toothless ran out of the Meade hall.
They arrived by the opening to the cove.
Stoick squeeze through the space to find missing dragons and his unconscious son.
He carries Hiccup back to the village.
The dragons return to the arena but not in the cages.
Astrid stop by the chief house reading Hiccup's diary while watching over him.
Brynhild ask "how is he?"
Astrid sighs "no response, but from his drawings, I can say he started drawing me after he made my ax for my tenth birthday."
Brynhild ask "how do you feel about him?"
Astrid sighs "I kinda impressed that he trained a Night Fury and the arena dragons."
