I have no idea where I wanted this to go but, I wanted to try writing something in Jack's perspective, I hope you enjoy!
Jack woke up with a gasp. He couldn't remember what he was dreaming about, but it left him feeling cold and out of place.
He rolled to his side, hoping he'd be able to cling to Hiccup without waking the other boy again.
But Hiccup wasn't there.
Jack's breath hitched.
"Hiccup?" This wasn't right. "Hic?" It felt too cold.
Breathe. Calm down. He swallowed the lump in his throat. Breathe, he told himself, Hiccup's fine, it's going to be okay.
Are you sure? Asked the stupid annoying voice from the back of his mind.
To smother said voice, Jack tossed aside their blankets and left the bedroom, trying to drown his panic in his stomach acids so it'll disappear and stay that way.
A quiet 'chirrup' from Toothless snapped him out of his haze. He looked down.
"Toothless?"
The black cat merely blinked and rubbed against his leg. He turned away and headed into the kitchen, where Jack heard something moving around.
He found his missing brunet putting away a bowl.
"Hiccup?" he breathed. Hiccup flinched and spun around.
"Jack!" he whispered, "Hey! I'm sorry, did I wake you? I woke up feeling a little hungry and- hey, are you okay? You look a little-" Jack cut him off, wrapping his arms around him.
"I just-I need-" he took a deep breath, "Can I just…hold you for a bit?"
"Yeah, of course," Hiccup immediately hugged him back, and Jack held him tighter, finally beginning to feel like himself again, "Do you wanna talk about it?"
"Maybe later, do we have anymore hot chocolate?"
"Yeah, do you want me to make some?"
"No, I'll make it myself, you want a cup?"
"Sure, hot chocolate sounds pretty good right now."
"Um, do you mind staying out here? At least until I'm done?"
"Of course, and then we can set up a movie or something when we get back to our room."
"Sounds good."
