When the six riders and six dragons get to the dragon island, they find its total chaos - the boats that weren't destroyed got set on fire and are burning, the Vikings are running away, and Gobber and Stoick are trying to keep the dragon that redefines 'monstrous' at bay long enough for some to get away.
Hiccup yells "Fishlegs, break that dragon down!"
"Tail made for smashing, little eyes, big nostrils, thick scales, relies mainly on smell and hearing and has seriously thick armor!"
"Ok, Ruffnut, Tuffnut, see if that thing has a shot limit - get it mad. Fishlegs, Snotlout, stay in its blind spot, make some noise. Astrid, you, Brightfire, Toothless, and I need to find Bloom!"
"On it, let's go!"
Brightfire looks around for a minute, then flies down towards one of the burning ships - Hiccup just spies the cage, and Bloom's coughing form. He and Toothless land, and Bloom coughs out "Get out of here, Hiccup."
"Not without you, sis. C'mon, lets spring this lock."
Bloom suddenly looks up and desperately yells "Fly!" Her voice changed somehow, and Toothless and Brightfire immediately take off like they didn't have a choice - and then the massive dragon's tail smashes into the ship, sending Bloom and Hiccup into the water.
Hiccup and Bloom both try to get the door open, no luck - and Hiccup passes out from lack of air.
Stoick jumps into the water, grabs Hiccup, and then is shocked when Bloom starts glowing bright orange - especially her hands. The cage suddenly blows apart, and they all go flying out of the water - Bloom, literally.
When Hiccup opens his eyes, Bloom's usual outfit has been replaced by a belly-showing top and skirt…and wings sprouting from her back. They look small and delicate, like they couldn't hold her weight up, but they flick back and forth as she coughs up water. "Bloom, what happened?"
"I don't know. I just got really desperate, felt heat surge through my body, and then…oh. Wow." She looks at her new outfit, sparkly skirt and top, handless gloves, boots, and then her look turns to amazement when she turns slightly and her wings respond.
"I guess those work then?"
"Yeah, I guess. C'mon, Hiccup. Let's go save the dragons we threw our lot in with." She lets out an ear-piercing whistle, and Brightfire lands in a streak of white, thrumming happily. Bloom hugs her head, saying "I know, I missed you to. I had to protect you though. And hey, flying is going to be even more fun now." Bloom climbs up and Brightfire takes off before Stoick can find his voice.
Toothless lands, and looks at Hiccup. "On it, bud."
Stoick says "I'm sorry, about everything."
"Yeah, me to. You'll probably want to say that to Bloom to though, fair warning."
"You don't have to go up there, you know."
"We're Vikings, it's an occupational hazard. Besides, my sister's up there and we'd do anything for each other."
Stoick grasps Hiccup's hand, and says "I'm proud to call you two my kids."
"Again, you'll want to tell Bloom that to. She didn't take the whole 'lot' comment well. Or the part about us not being your kids."
Stoick grimaces, remembering times when Bloom would stay mad for days and sometimes weeks - this is definitely going to be so much longer if they survive.
Toothless takes off, and it becomes a fight to end all fights. Fishlegs gets crushed by his Gronckle, which then rolls over, and Snotlout is stranded on top of the dragon's head - luckily, he's got a hammer to smash into its eyes, until it gets annoyed with that and he nearly falls to his death. Astrid nearly does the same, until Toothless catches her and sets her down on the ground while flying.
Then, it's just Bloom and Hiccup still on their dragons - it's a good thing the Night Fury/Light Fury species is easily the most agile of them all. They're twisting around the thing's shots, dodging its fireballs, and Bloom's quickly proving she's got more than just wings to use - she's also got her own fireballs.
Brightfire will shoot the thing, and then a blast of orange will also hit the massive dragon moments later. In a normal fight, one would start feeling sorry for the thing, getting hit with blast after blast from all directions - that thing doesn't seem to be very hurt at all.
Even when they get the thing - which Hiccup thinks they should call the Red Death - flying, it's still getting bombarded by shot after shot from everywhere.
Down below, the Vikings are watching in awe as the sky lights in in purple and orange, the outline of the massive dragon that nearly killed them all clear for a moment each time. Astrid whispers "They're beating it…they're actually beating it!"
Of course, when the thing falls to the ground and explodes, they all cheer - when a new kind of dragon they've also never seen appears, looking like it's made entirely out of fire and landing on the ground before disappearing, nobody knows what to make of it. Nobody human, at any rate - the dragons all go still, almost like their waiting and hoping for something.
It's when they see a bright white body that they realize Brightfire's there - which may mean Toothless, Hiccup, and Bloom are there. Stoick and Gobber go forward, and find Toothless and Brightfire apparently alone.
Stoick closes his eyes, muttering "What a fool I am…"
Toothless looks at him for a minute, then slowly opens his wings to reveal Hiccup in his limbs, safe and uninjured. Stoick presses his head to Hiccup's chest, hearing a strong, steady heartbeat, and says "He's alive! You brought him back alive! Thank you." He presses his hand to Toothless' head for a moment, who almost seems to be nodding.
Brightfire, however, is a lot more hostile towards Stoick - Bloom probably told her what happened, and the fact that she was in a cage doesn't help matters any.
Hiccup groans just then, and says "Oh, what happened?" He sits up, only to be crushed in Stoick's arms.
"Oh, you're alive. And awake. Hiccup, what happened up there? That first dragon fell to the ground and blew up, but then a second, even stranger one, landed and disappeared. And then here you all are."
"I don't know, I was riding Toothless, we hit the dragon's tail, and the last thing I heard was Bloom shouting 'no!' After that, waking up and getting my ribs cracked. But, really, I feel great. Like I didn't just get hit with a massive tail and should be dead. Where's Bloom?"
"Seeing as Toothless had you, I'd say in this one's grasp - but, uh, she doesn't seem very happy with me."
"Well, I sorta told her what happened. And she's really protective of Bloom for some reason." Hiccup kneels beside Brightfire, whispering "It's over, Brightfire. We won. You've got Bloom?" He gets a head nod, and sighs in relief. "She's alive, right?" Another nod. "Can we see her?" Brightfire bares her teeth at Stoick, growling warningly. "It's alright, he's our dad." That gets him a look like 'how stupid do you think I am?' from the dragon, and Hiccup says "Look, I know things were said and done. But we're both worried. She wanted to protect you, Brightfire. That's why she told him she could find the island. That's why she let herself be locked up and all."
After a minute, Brightfire unwraps her wings to reveal Bloom, unconscious and changed back like she didn't have wings and a sparkly outfit on less than an hour ago. Toothless sniffs her body as Brightfire nuzzles her hair, and she moans and shifts slightly.
Stoicks sighs in relief, "She's alive, she's alive. Thank you, Brightfire."
Hiccup looks down, and gets a pretty good shock once again - Toothless' tailfin has grown back. "What? Toothless, how…look at your tail!"
Toothless holds his tail up and stares at it for a minute, flexing the fin one way and another like he's testing it to see if it works - it does, like it was never torn off in the first place.
Hiccup and Toothless stare at each other for a minute, and Hiccup finally says "It had to be Bloom. Dad, half of Toothless' tailfin was torn off. Remember when I said I shot down a Night Fury? Well, it was Toothless - and half his tailfin was torn off in the crash. I made a prosthetic so he could fly, but…but the fin itself got burned away by the Red Death. But now…" He just gestures uselessly at the new fin, and Toothless sniffs at Bloom's body again and chitters almost sadly. "Ok, let's get her back home. Dad, think you can - ok, never mind. Brightfire's already growling at that idea."
It ends up being that Brightfire carries Bloom back to the ship herself, flying down to it and keeping any humans but Hiccup and Astrid away at all times - worrying a lot of people, but its abundantly apparent that the white dragon doesn't care.
And Stoick doesn't get to go anywhere near Bloom, he actually gets tackled to the ground by Brightfire, and Toothless' roar and a warning shot has most people backing away carefully from what appears to be his mate.
When they get back to Berk, Stoick isn't even allowed up in Hiccup and Bloom's room - which gets him mad, but he's also given the dragon no reason to know she can trust him. He locked Bloom up in a cage, how could he do that?
It seemed like the right move to make, at the time - when he was furious and feeling betrayed - but now he regrets it with every fiber of his being.
Especially when Brightfire lets Hiccup up and over to Bloom's side in an instant, but refuses to even let him past the doorway - or it'll be Toothless in the door and not the white dragon, who'll then be found lying her head on Bloom's torso and trying to wake her.
After a few days, and some help from Hiccup - after a very long talk between them where Stoick mostly sat and didn't say a word while Hiccup laid out every single reason why he befriended a dragon and preferred his company to that of the village - he's allowed in their room.
Those reasons? They seem to be endless.
Toothless never hurt him.
Toothless never called him Useless.
Toothless gave him a chance to prove himself.
Toothless actually made him feel like he wasn't a waste of space.
Toothless actually cared about him in a way nobody but Bloom and Gobber ever showed. And seeing as Gobber wasn't really made for being a parent, that's highly dangerous coming from him - even Stoick knows that.
The rest of the village minus Bloom only ever belittled and insulted him.
He, the kid's father, was only ever either angry or disappointed in him - he disowned the siblings for trying to find a better way than an endless war and constant fighting.
He never took any kind of interest in Hiccup's wellbeing whatsoever, never stepped in to stop the bullying that happened constantly, no matter what he tried to be more like the others he never once even said he cared for Hiccup.
How he said he almost gave up on Hiccup, that hurt worse than most of it all.
How Hiccup is practically an exile in the village because he's so different.
How it's the same for Bloom, but she doesn't care what the village thinks of her so it's no problem to her whatsoever.
AN: Hey, everyone - finals are over, and I'm out of school! Hooray! Sorry I started a new story right in the middle of this one - got hit with the idea and thought it was too good not to try. As for the last review i got for this story, yes, I'm going to add in the other HTTYD movies in with this story...eventually. Anyway, enjoy! I've got about a week off from classes of all kinds, so I'm fully planning on updating my two stories in that week. Please review if you've got suggestions!
