Hiccup knew he shouldn't have let him in.

It all started when he noticed how things suddenly changed the place where he had left them. First, it was a candle. No big deal. It could've had been his imagination and actually, it must had been a coincidence.

He thinks he had put it on the kitchen counter that night when the lights were out in the whole street. When he bent down to put away the forks that had slipped out of his grip, the lights turned on, apparently the storm was going away but the candle wasn't there anymore. He shrugged it off until he found it on his nightstand.

He owed it to that time when he played the Ouija board with his friends. He had invited them to come over on rainy night once again, it was the raining season after all and when they finished watching The Lego Movie, Ruff and Tuff suggested the wicked game.

It was thrilling at first. The twins and Fishlegs wouldn't stop giggling; Snotlout kept glancing nervously around and trying to cover it up. Astrid snickered and just went with like Hiccup because why the hell not? They were bored teenagers.

When their fingers were connected on the small Ouija triangle and it suddenly started moving once they've made the stupid questions, the teenagers shrieked excitedly. Hiccup just laughed and humored them just because of Snotlout's face. There weren't even making serious questions and he knew that it was mostly the twins who were moving the triangle. He admits he pulled it to the 'YES' answer when they asked 'Is Snotlout a crybaby?' to which Snotlout spluttered indignantly and didn't want to play anymore.

Once the excitement died out, Hiccup made sure to follow the instructions on the box to close whatever portal they had 'opened' because he had seen enough scary movies to know what happens when stupid teens play the Ouija board and don't finish it appropriately and he was sure as hell that he didn't want a stupid ghost or spirit wandering in his house. His dad would kill him.

Deep down, he had always been kind of a believer. So, he ended the game before 12o'clock.

As expected, nothing happened that night or the next two. It was on the third night when Hiccup worried.

He had been sleeping peacefully on his bed until he heard the murmurs at the back of his mind. His sleepy head thought at first that it was Gobber or even his dad but their voices were deeper. When his brain finally registered that it couldn't be them, Hiccup cracked an eye open and looked around his room. He saw nothing. He glanced at the alarm clock (It was shaped like a dragon, by the way.) and it read 4:32. Not even the spirit's hour or whatever it's called. He ignore it since he couldn't hear the voice anymore, it had probably been a dream.

His mind was just entering in the realm of unconsciousness when he felt a weight on his bed by his foot. He jolted awake with a gasp.

"Oh, shit! Toothless!" He exclaimed but the Komodo dragon wasn't there. "Toothless, don't do that!" He crouched down and looked under the bed where Toothless usually sleep but he liked to slither under Hiccup's covers every now and then. Especially now since it was October and the wind was getting chillier and chillier because of the rains and Hiccup was very warm.

Again, Toothless wasn't there and it suddenly hit Hiccup the memory of his dragon falling asleep downstairs on the couch when he ate too much peanut butter.

"Shit…" He cursed.

After that, he told Astrid everything and little by little he believed more. He told her that maybe he they hadn't closed the portal right, maybe they shouldn't have played the Ouija so close to Halloween. Astrid had remained calmed and rubbed his back. "Don't believe in it; don't even pay attention to it. I've read that the more attention you pay to it the more it will get to you. I'll try to figure something out." She advised and Hiccup followed her instructions.

The third time something happened was when Hiccup and Toothless would catch glimpses of something near the windows. Always near the windows. Hiccup would turned around and act like he had seen nothing but he would whisper to Toothless.

"You saw that, didn't you, bud?" He inspected the cover of his magazine, trying to look nonchalant.

Toothless would look pointedly at the window, as if the thing was still there and then he would curl around Hiccup's waist protectively. He wouldn't let him go until the room got warmer. That was something Hiccup didn't notice until that day. Every time something happened, the room where he'd been was colder. Strangely, he also noticed that nothing ever happened when he took nice warm baths, where steam would feel the room or when he was in Gobber's forge.

Those were all the hints that Hiccup needed to know that he wasn't dealing with a demon. Thank Thor.

"Dad, I think there is something in the house,"

"Something in the house?" Stoick asked.

"Yes, like a ghost or something," He elaborated.

Stoick, unimpressed, glared at Gobber who was making pancakes.

"What?! It wasn't me!" Gobber argued. "I didn't tell him anything!"

Stoick shook his head and continued reading his newspaper. "There are no ghosts, Hiccup." And that was all he said to that.

But the sights, the sounds and even what he felt was making everything harder to ignore until Hiccup got the point where he understood that this wasn't something that would go away by its own. But what could he do? Other than whispering "Go away…" softly every time he thought he saw something by his window.

The fourth time something happened was when he finally saw him. He was sleeping again but now even the slightest sound would wake the paranoid teen, so when he heard the knocking on glass, his eyes snapped open. It wasn't even knocking; it was like someone was just hitting his window slightly with their nails.

Hiccup had heard stories like this and what they all had in common was that if you turn and look, you're dead. Obviously, he wouldn't look but he wouldn't just go back to sleep and in no way in hell would he stay there and do nothing.

So, Hiccup slowly sat up and got out of bed, his green eyes firmly planted on the wall. The knocking slowly stopped and the teen felt watched. That only made him more curious. He took a step and then another, cursing that Toothless wasn't there with him and gradually made his way to the door, but not before walking across his mirror.

There, from the corner of his eye, Hiccup saw something crouching at the other side of the window. For a second, he thought that maybe he was imagining the sounds, but really seeing something there, seeing that he really saw, heard and felt those things, surprised Hiccup so much, that his gaze ripped itself from the wall and went to the crouching figure.

And he saw him. The thing… the boy who had made Hiccup's days a nervous wreck. He had white hair, or at least Hiccup thought he did. It had a grayish tint, too. Blue and wet eyes. His skin… it hurt Hiccup to watch his skin, it was so white! But it had purple and blue-ish in places like his ears, the tips of his fingers, his lips, his chin. It was almost like he had frost bite and even a caress would ruin the flesh.

Hiccup gasped and turned reflexively, half-expecting to the boy not to be there anymore, but he was. He was still there. Hiccup's eyes were wide as plates and soon the boy mimicked. The auburn shifted in his place, position ready to flee. The other boy seemed to notice this. He raised his hand slowly as if trying to look harmless or to calm Hiccup. But this only scared Hiccup more and spurred him into action.

He sprinted to the door and almost ripped it open from the force, but before he could get out of his room, he heard the boy calling out,

"No, wait, wait!"

Hiccup ignored him and went directly to his dad's room as fast as his pajamas would let him. He burst the door open and shook his dad awake.

"Dad, dad! There's a junkie outside my window and he's trying to get in, dad! Call Gobber! Where's Toothless?!"

Stoick jumped from his bed and looked around alarmingly before his son's words reached him and he ran to the room with Hiccup right behind him.

"Dad, be careful!"

Stoick unlocked the window and Hiccup felt a chilly breeze getting in. Stoick tuck his head out, checked the surroundings, the roof, the first floor. Snowflakes fell slowly and kissed the ground.

"There is no one there," He declared. "Stay here, I'll go tell Gobber." He locked the window again and disappeared in the corridor.

Hiccup nodded dumbly and panted, trying to even out his breath. Snowflakes gathered by his feet and the room was colder than he remembered. Behind him, he felt a presence.

'Let's get this over with…' He thought.

He shut his eyes and turned around, counting to three before opening his eyes. There he was. Inside his room. Again. At least now, his suspicions were confirmed, only Toothless and he could see him and he could turn invisible whenever he wanted to. This wasn't a junkie; this was actually something of the paranormal.

He stared at him and clenched his fists, waiting for the boy to lunge at him just like in the movies before he killed him. He just wished he had seen Toothless one last time, hug his dad more and listen to Gobber more frequently. Good-bye, world.

He glared at the boy and waited. He couldn't even get words out of his mouth. The boy, and now that Hiccup gets a good look at him, looks his age. He stares at Hiccup incredulously.

"I knew it… I knew you could see me!" The boy jumped excitedly in his place and pulled his hair, a wide smile decorating his white face but soon froze and looked pointedly at Hiccup. "You can see me, right?" He asked worriedly.

Hiccup took a breath before answering. "Listen, I didn't mean to wake you from you slumber or whatever, but my friends and I were just playing. We didn't actually think that a ghost would really show up! I tried to finish the game like we should but apparently something went wrong or- or- or- I don't know, because you're here and-"

The boy abruptly leapt from his place, cutting Hiccup's blabber off to grab his face. Hiccup gasped because of the fright and because his hands were ice cold.

"Don't, don't, don't!" Hiccup tried to pull away but his hands were hard and firm.

"No, no, no! Shhh!" The white-haired hushed, pulling him closer and nuzzling his face against Hiccup's. "Hiccup, shh! I'm not going to hurt you. I've just wanted to meet you for a while. Don't be scared, please!" He said desperately.

Hiccup pulled his freezing face aside to ask, "How do you know my name?!" And although the boy had asked him not to, the auburn was getting more and more scared and it showed through his breathing.

"Please, let go of me. You're really cold," He begged and pushed against the other.

"What?"

"I said let go of me, please,"

The boy paused for a moment, like deciding whether he should let go or not, before reluctantly pulling away. "Oh, right, right. I'm sorry,"

Hiccup thought fast. "No, I am. I shouldn't have played the Ouija board that night. I won't play the Ouija board ever again, so please…"

"Ouija board?" He seemed confused for a moment before chuckling. "Oh, I'm not a ghost," The teen noticed that the paranormal entity or whatever he was, was getting closer indiscreetly and with every step he took, Hiccup took one back.

"Then, what are you?"

"Well," He chuckled nervously. "I'm a guardian, Hiccup. You ought to know that."

"I- really?"

"Yes," He hissed. "Don't you remember? I've known you since you were a little kid!" He approached swiftly and the sight honestly freaked Hiccup out. He tried to get back but collided with his nigh stand, knocking his alarm clock off of it.

"I- I- I'm sorry but I don't…"

"Hiccup," The slender boy once again grabbed Hiccup's cheeks, trapping him in place. "Look into my eyes and say you remember me."

Hiccup grabbed his wrists and looked into the other's blue eyes. He was scared shitless. What if his dad came back and saw them? He contained his breath, one because he thought it felt wrong that his warm breath mingled with the other's cold one and two because he felt that if he moved his lips, they would clash with the boy's.

Hiccup looked down; he was at loss for words. He didn't know this guy! And he thinks that he would remember someone as strange as him.

Blue eyes widened expectantly until he seemed to read what was on Hiccup's mind. He, too, looked down dejectedly before brightening up again.

"You're all changed. You were so tiny back then," He started. "Well, you're still tiny now but," He chuckled nervously.

"Yes, I was little- er, littler," Hiccup said uncertainly, gripping those cold wrists. The boy was now caressing his face with his thumbs and picking every detail in the auburn's face. He quickly slipped away from his grasp before he started to not feel his face and now that the white-haired wasn't towering over him, he breathed slowly.

He crossed the room and sat on his bed weakly. "Are you going to hurt me?" He asked honestly. In the movies, bad things happen if you trust the spirits.

"What? Hiccup!" The boy looked alarmed. "Why would you think that?" He tried to get closer but Hiccup jumped to his feet, ready to run and the boy froze in place.

"Are you going to hurt my family?"

"I wouldn't want to hurt Stoick, Toothless or Gobber," He answered and Hiccup wanted to cry. How did he even know their names? What is he up to?!

"Then, what do you want?"

"Nothing…" The boy said but he didn't look sure himself so Hiccup didn't believe him. In any case, he decided to humor him.

"Okay. In that case, I don't want to see you right now," He stated.

"But, I-!"

"Please." He said tiredly.

After seconds that Hiccup thought were more like endless minutes, his reply came.

"Okay…" He said sadly. Hiccup ignored his tone and walked out of his room without looking back.

He ran downstairs once he was in the corridor, found Toothless sleeping again on the sofa and lifted his heavy head to let it rest on his lap. Toothless didn't even notice, just snuggled into him while Hiccup's eyes were still wide and scared. Who would have thought that talking to a spirit would be so exhausting? Now that the adrenaline had died out, he felt weary as hell. But he didn't close his eyes until his dad and Gobber were back, safe and sound.

He didn't see the boy again that day. He hoped it had all been a bad dream.

Unfortunately, it was not.
