Twitch and Jack returned to the car and drove back over to the camp to find Hiccup still alive and okay, thankfully. They explained the entire story to him from finding the abandoned research facility to realizing what has been going on there that lead to the creation of the zombies.

"And that's what happened." finished Jack.

"Woah." gasped Hiccup with bulged eyes. "That's so weird. So someone's out there controlling these things?"

"Yep. But let's worry about that tomorrow." said Jack with a yawn. "We should head to sleep."

"Alright."

That night while resting in their tent, Hiccup was still wide awake while his friend was fast asleep in his cot. Hiccup could swear he could hear something coming from outside their tent.

"Psst. Jack. Jack, wake up." whispered Hiccup.

Jack groaned groggily, half-asleep and answered, "What?"

"Y-You hear that?"

He only got a loud snore in response.

"Jack!" Hiccup hissed loudly, which earned him an annoyed groan.

"Go to sleep."

Hiccup sighed and slowly arose from his cot and out of the tent to investigate the strange noise himself. Sure enough, there was a dark figure outside wandering through the campsite.

"Huh?" This made Hiccup raise an eyebrow and red flags to go off in his head as he slowly and quietly followed to mystery person who, unsurprisingly, turned out to be Twitch. He entered his office while Hiccup hid behind a bush. Over the sounds of crickets and other night sounds emitting around the forest, there appeared to be a conversation going on inside, which left Hiccup confused. Who could Twitch be talking to?

The voices were muffled, but Hiccup could almost make out the sentences, explaining something about "I think I've gained their trust" and "they're getting close". The voices ended for a brief moment, leaving only silence inside. Then all of the sudden, there was a deep-pitched voice shouting, "You fool!"

Along with the sound of the slashing of flesh with a blade, a mess of blood splattered on the window. Hiccup gasped with absolute horror at this and retreated back to the tent before he could be detected. Hiccup could not get any sleep last night after what he just witnessed. He was 90% he just witnessed a murder. Hiccup laid in his bed in a fetal position, eyes wide open, red and tired as he stayed awake, hoping nobody would enter their tent and kill them too.

The next morning, Jack awoke from his sleep and stretched his tired bones with a yawn.

"How'd you sleep, buddy?" asked Jack.

"Jack." began Hiccup, staring at his friend dead in the eyes.

"Yeah, Hiccup?"

"Something happened last night." Hiccup replied with a hint of fear. "Come with me."

Confused, Jack followed his friend over to Twitch's office where Hiccup witnessed the murder the night before.

"In there." Hiccup explained, pointing at the building.

"So this is where you saw Twitch go?" asked Jack.

"Open it. Carefully." ordered Hiccup with an uneasy and even more frightened feeling that there would be something they won't unsee. Jack rolled his eyes at his friend's behavior right now, believing he was just overreacting, but he reached for the door knob, nonetheless.

"Relax. It's not like it's gonna-" Hiccup gasped with shock once Jack opened the door. To his surprise, there was nothing inside. There was no body, no blood and Twitch was no where to be seen nor that mystery person he was speaking with. Jack and him entered with Jack not shocked or worried in the least.

"It's...a house. Great." Jack shrugged, certain that his friend was freaking out over nothing.

"Wait, what?!" Hiccup cried, not believing this one bit. "But there were screams and Twitch...and...and...and..."

"Don't you think that maybe the lack of sleep got to you a little?" asked Jack, shaking his head.

"No! I swear! I was here last night." Hiccup persisted, pleadingly. "I saw things-"

But all of the sudden, Jack found a doorway on the floor and opened it up to see a secret hole inside, which caused him to think that his friend might be right.

"Oh, a secret." He exclaimed with surprise. "Maybe you're onto something."
