Notes: Cookie Jar is a bunch of unrelated one-shots focused on Hiccup's adventures. Some chapters will be full-fledged one-shots while others will be notes, rough ideas, or even a mix. Some slash. RATING MAY GO UP.

This chapter is a one-shot in note-form.

Summary: When Hiccup encounters a time-traveling dragon believed to be a myth, he is dragged 5 years into the past – just before he shot down Toothless. It's hard enough returning to the present but, given his terrible luck, he's on a time limit: a fleet of possibly hostile Romans steadily approach Berk in the present. He needs to return home fast. Especially since he hates being a runt again. (Time Travel AU)

Timeswap

Timeswap is a crystal-esque dragon with a special gem in its chest: two upside-down pyramids connected together, resembling an hourglass shape with sand inside of it. (Origin of hourglasses originated form this dragon) The gem is a blend of spit, sand, and glass. Dragon spit protects some sand from being heated/turned into glass by the dragon.

Trader Johann visits Rome and swaps one of Hiccup's inventions (catapult shield...flaming sword?) which has the Berk crest on it for a hourglass artifact from Roman Black Markets. (Bending canon time here but Berk doesn't know Johann's a traitor yet)

The hourglass is actually a gem once stolen from Timeswap. A gem the Timeswap wants back.

The Black Market merchant winds up selling the invention to a Roman general. In turn, the soldier gives the invention to the Roman Emperor as a gift in hopes of earning positive favor.

The Emperor is impressed with the workmanship, never having seen anything as functional AND intricate. Emperor sends a messenger to Berk asking for the inventor of the device to join Rome.

Johann travels to Berk and trades the hourglass and a journal documenting the myths of Timeswap dragons to Hiccup for another one of his inventions. Johann leaves. (Johann prolly knew the dragon was real because of the Dragon Eye? Somehow? He tryin' to get rid of Hiccup. Jerk)

At night, just after Hiccup and Toothless' evening flight, Hiccup reads through the Timeswap journal for the millionth time and plays with the hourglass, wondering how it was made because what was this clear texture? How was their sand inside that same substance?

Toothless encourages Hiccup to sleep. Hours later he's awoken by the Berkian Guard horn and he rushes outside to find an unfamiliar ship with a vaguely familiar crest. It takes a moment before he recognizes it as the crest on the Timeswap journal.

The lone Roman Messenger docks and delivers the scroll. Blearily, Hiccup allows the strange looking stranger in robes to stay the night.

Next morning he writes a response, declining the offer. "I'm chief to my village, I can't up and leave! Also, where's Rome?"

The messenger leaves. Emperor receives message and gets mad. How dare someone refuse him! So he sends out a fleet to take the inventor by force to use as a personal blacksmith/inventor. Rome would benefit from brains like his!

Hiccup has no idea he ticked off an Emperor. Instead, he chiefs around the village and takes moments to play with Toothless and fidget with the hourglass. It's the genuine gem, not a replica. Hiccup doesn't know that since he has no point of reference.

The Timeswap tracks down the gem to Berk and in turn to Hiccup.

Berkians starstruck by the shining, fantastical new dragon

Hiccup approaches Timeswap despite Toothless freaking out and Fishlegs comments on the empty slot in the dragons chest. Hiccup realizes it's the same shape as the hourglass and he, absent-mindedly, mentions that he thinks he has what the dragon wants.

Oddly enough, the ancient dragon seems to understand perfectly. (Time travel gives it a wide range of exposure to different languages)

Timeswap follows Hiccup to his house while he chatters to Toothless about the hourglass and how the journal notes match the dragon they see. Toothless unhappy and uncomfortable all the while keeps a stern eye on Timeswap.

Hiccup in his house mentions how he misses Stoick being around and especially being chief so he could return to exploring and have more guidance. Outside, Timeswap listens, seemingly understanding.

Hiccup emerges from the house with the hourglass and gives it to the Timewasp just as the Berk Guard blows the horn. Roman fleet approach.

Hiccup groans as he nears the docks with Timeswap idly watching nearby. "Wish Dad were here, he'd know what to do..."

Hiccup sends the Berk Guard to fly out and investigate, Before he can find out WHY the Romans are there, a bright light flashes in front of Vikings and Romans alike.

Hiccup, as present Berks knows him, and Timeswap vanish.

In their place, a 15 year old Hiccup now in a 20 year old body stumbles forwards, horribly confused and feeling a throbbing headache.

In the past, Hiccup falls flat on his back, the bola launcher sitting in front of him. An awful headache pulses in his temples as a distant night fury screams.

He blinks, dazed, until a monstrous nightmare steps on the wood and he scrambles to his feet. His two flesh and blood feet.

Horribly confused but having no time to dwell on it, Hiccup tries to run forward only to misjudge the length of his legs and trip as his weight hits the ground before he was subconsciously ready. Like walking up steps and forgetting there's no more.

He yelps and rolls to his feet just before the rouge nightmare can claw him. He runs towards the village only to realize everything's wrong.

Dragons and Vikings are fighting once more. The buildings themselves are different but familiar. Why are they fighting like it's a raid again? Why does he have two feet? Was that Spitelout running past and yelling at him to get inside? Why would he get inside? He was that man's chief!

Wait, why did Spitelout look younger?

The nightmare continues its chase as he weaves through the village, limbs not quit working the way they should. The dragon nearly catches him with a blast of fire as he hides behind the metal portion of a pillar, sucking in air.

A familiar voice booms. "Son!"

Hiccup freezes.

Impossible.

Stoick himself lunges at the dragon, punching it clear across the snout. Hiccup openly stares. Because that's his dad right there. Alive and living and so very much there.

He must be dreaming of an old memory because it's all impossible but the heat feels real and the voices are loud and everything's familiar but not quite right all the same.

The wooden pillar falls and tumbles through the village towards the docks. Hiccup swallows as Stoick turns a disappointed scowl onto him. He'd forgotten how much that look had hurt long ago.

Stoick scolds him in front of the village, but instead of his usual snarky remarks he just stares, drinking in the vivid dream for all its worth. The unusual quiet from his son startles Stoick enough to cut his scolding short and send him home with Gobber.

After the front door shuts, Hiccup rushes through the back door and flees to the forest, needing to think. He follows the familiar path to the cove and jolts when he finds the broken trees and soon Toothless tied up.

Hiccup, remembering this all too well, apologizes to Toothless and repeats the motions. Toothless screams at him and flees.

Instead of fainting, he follows Toothless to the cove.

Toothless is NOT happy to see him until he ditches the knife. Hiccup tries to approach but Toothless warns him away. Hurt, he leaves.

He returns home to Stoick telling him he'll be joining dragon training. Wishing the dream would end already, he knows the drill and heads to his room. Were the stairs always that long?

Next day, he wakes to two flesh and blood feet. Groaning, and deciding to ditch dragon training because it's all just a dream, after all.

He heads to the cove with a basket of fish. He bribes Toothless and starts talking to him, explaining his situation and Toothless looks at him oddly before trotting away. Hiccup groans and pulls out his journal, doodling and writing, he slowly stars realizing its not a dream.

Timeswap. The time traveling dragon.

He realizes he must've switched places with himself. But if he was in the past, then were was the past Hiccup?

~oOo~

Past Hiccup stumbles forwards with a headache and in a world so incredibly not his own.

Everyone's older and callin' him chief and they're about to be attacked and what is happening here? Why don't they ask for Stoick?

And then he looks down to find he's missing part of his leg.

Which brings a whole slew of questions.

Like:

"How do I walk?"

"How did I lose my foot?"

"Is my not-foot gonna fall off?"

"Does it rust?"

"Do I oil it?"

"Still skinnier than I wanted to be as an adult"

"Wait, I have a mom?!"

"Where's my dad?"

And everyone exchanges uncomfortable and odd looks cause, "Hiccup...Stoick's been dead for weeks."

So yeah, Older Hiccup swaps bodies with younger Hiccup. Younger Hiccup is so fuqin confused and prolly kidnapped by the Romans. When Hiccup switches somehow, he's understandably confused to find himself on a Roman ship like what da fuq?

Notes: Watched HTTYD Race to the Edge and felt an itch to write that just had to be scratched.

Also, I plan to maybe write & post a Teen Titans BBRob story for my friend Lymaria. It was her birthday yesterday and I still haven't given her a present yet. Figured a fic would be a good gift but I'm lacking in ideas.

Thanks for reading and feel free to leave a comment with thoughts, feels, or even ideas!
