A/N: Here's a map of the place, so you'll have a better understanding of the situation. The red lines show where the impostor can move through the vents.

The seven of you woke up at the cafeteria again, hearts heavy and no evidence or information about anything. Taehyung's face was hard and everyone threw weird glances at him because of the words he said.

The truth is, no one wanted to believe him. Cause if really one of you was killing people, if one of you had actually killed Yoongi, that would make things even more confusing.

"What do we do now?"

"It depends on what we assume. Yoongi died even though we were all together. Assuming there's someone in here that kills, and it's not us" Namjoon said, looking at Taehyung "I think we should split. It'll be easier to find out if someone else is also in here"

With the corner of your eye, you saw Jimin was about to say something to you, but Taehyung just pulled your hand and walked towards the direction of MedBay.

"Let's finish our tasks" Taehyung said and you left the others behind.

It was the two of you at MedBay. Your task there was to submit scan. You looked around and saw a round base on the floor.

"I think you should stand on there" he said and pointed at the base.

As soon as you did, green lights scanned your body. While you were doing this, you and the boy had locked eyes with each other. You could see his anger and smiled softly at him.

"We're all angry, Tae. And we're all worried. But all we have is each other, and we should put trust in that. There's no way one of us would kill. I think Namjoon is right, there's probably someone in here hiding, maybe the one that kidnapped us"

"Don't smile at me like that. You're dying inside and I know it" he said

You tried to forget Yoongi's body, bathed in blood.

"If... if one of us killed Yoongi... I swear I won't be able to trust anything anymore" you said and looked away so he wouldn't see your teary eyes "This doesn't seem real. Tasks? Impostor? Yoongi dead? The only reason I'm a calm is because I don't think it's real. I'm sure I'll wake up in a while."

"Yeah..." he said "You'll wake up. And I hope I'll be next to you"

He was so sweet, like always. So protective, but sometimes it was too much, making you feeling weak.

In the corner of the room you noticed an iron door at the floor, being closed.

"What's this?" you asked and Taehyung approached it and tried to open it with no result.

"Look's like... a vent? But I can't open it"

As soon as he said that, Jimin entered. He looked at the both of you but then spoke to you.

"Y/N, would you mind if I said some words privately with Taehyung? Jin is at the cafeteria, you'll be okay"

You didn't know what the boys wanted to say with each other, but you just nodded before leaving them alone.

"Take care" Taehyung said when you were at the door, and you smiled bitterly at him, as if you could do anything about it.

Jin was fixing wires at the cafeteria. You stood next to him. He was breathing heavily and seemed unable to focus on what he had to do.

"Are you okay?" you asked and he shrugged

"Who is okay? Name one person in here and I'll give him a reward. I'm extremely scared, I'm extremely confused, no one has any idea what's going on, Taehyung thinks it's one of us, I'm..."

He didn't manage finishing his words, when you heard Hoseok screaming.

"A BODY!! NAMJOON!!!"

Who is the impostor?

You're fucking kidding me...

Namjoon's name, had an X on it, just like Yoongi's. Now you, Taehyung, Jimin, Jin, Hoseok and Jungkook were standing around the circular table, having a screen to vote.

"What the fuck happened?" Jimin asked confused

"I really don't... that's so weird... it can't be what I think it is..." Hoseok was trying to speak but there seemed to be a chaos in his mind, and we was unable to put words into sequence

"Take it easy, just say what happened" Jin said but he wasn't calm himself "We were all together at cafeteria, you and Jungkook said you're going to navigation, Namjoon fixed the wires at cafeteria and said he's going to find you guys. And now he's dead"

"I really... I entered the navigation first, I was doing a task and Jungkook came in too, when I finished I was about to leave, and right outside the door there was... Namjoon... dead... oh my God this can't be real... I don't understand, Jungkook, didn't you see him when you entered?" Hoseok said and all of you froze in fear.

If what Taehyung thought was true, if it was one of you...

All the attention was now on Jungkook, who couldn't believe what he was hearing.

"Do you seriously... Guys come on, I'm as shocked as you are, I entered navigation after Hoseok and he indeed left first, but I swear I didn't see Namjoon, Hoseok just suddenly yelled, and when I turned around I saw him with the body..." Jungkook defended himself

"Man, I don't want to accuse anyone, I don't want to believe what Taehyung said, but it all happened so fast, I can't help it but assume... oh my God..." Hoseok murmured

"The truth is... the rest of us were pretty close. I left Jin and met Tae and Y/N..." Jimin said

"And I met Jin at cafeteria... if it's one of us... it's one of you two..." you said in disbelief

"That's right!" Jungkook snapped "It could also be Hoseok...I only turned around when you screamed, but you could have faked it..."

"Why would I report the body I killed then?" Hoseok yelled at Jungkook.

It all seemed so odd. Jin was at the verge of tears, Taehyung was avoiding showing any feelings, Jimin had wide open eyes, Hoseok and Jungkook were accussing each other.

And two of your closest friends were dead...

"Do we seriously... like seriously... try to find who of us... killed Namjoon and Yoongi? Are we seriously accussing each other of being a murderer? Of lying and pretending to be..." Jimin said

"A crewmate" Taehyung finished the sentence

"That's insane... this can't be..."

Why haven't I woken up from this nightmare yet?

That's all you could think of when you opened your eyes again and the five of you were at the cafeteria. You noticed that there was a table there, with a red button on, saying "emergency button" with a timer next to it, counting backwards, probably before being able to press it.

"Hurry, go finish your tasks so no one else has to die" Jin said and you all nodded.

You and Taehyung ran at electrical, where you had to fix wiring, and then went to weapons to clear asteroids. You didn't have the same tasks with Taehyung, but he insisted you had to do yours first.

Your heart was getting tighter and tighter.

"I can't take it Taehyung" you told him as you were walking

He stopped you and hugged you, putting you tightly in his embrace. Being with him the whole time was making him the only safe person in there, and that spread a warm feeling in your body.

"I know sweetheart"

Sweetheart...

Instead of making your heart beat faster, it sounded kind of weird in your ears. Was it the first time he said it? But why would it be weird? It was Taehyung... your boyfriend.

So why?

"GUYS!!! GUYS!!! IT'S JIMIN" Jungkook was heard.

Lights off. Lights on.

Who is the impostor?

voting time: 120 sec

Jimin was nowhere to be seen. On the screen, there was an X on his name. Jungkook was pale and trembling in fear.

"He was in admin. He was dead in admin, where Yoongi died before too. But Yoongi's body wasn't there. This is insane this can't be true... Jimin..."

Jimin...

In some way you'd managed to stay calm at the two previous deaths. You had managed to persuade yourself that it was a dream. But it felt so real, and realization hit you; what if you'd never see Jimin again?

Your heart was bleeding inside. The pain was unbearable and you fell on your knees. Taehyung saw you but didn't ran to your side. Instead, he looked at Hoseok and Jin who were looking each other in silence.

"The two of you... why are you like this?" he asked them and Hoseok was the one to speak.

"I remembered there was a security room... from there you could see only corridors from cctv. One of the cameras shows right outside admin. I went immediately at security and watched the cctv. Jin came there as well after he finished his task at cafeteria. We were both watching. The only person that ever entered admin was you, Jungkook" Hoseok said and no one spoke for a while.

Jungkook cried. He cried a lot.

"YOU CAN'T MEAN THIS, RIGHT? YOU CAN'T MEAN THAT I WAS THE ONE WHO KILLED JIMIN!"

"I'm just saying... what we saw..." Hoseok said

"And previous round, Jungkook, you were the most possible suspect" Jin added.

You looked at Jungkook. He was still crying, yelling and yelling things to defend himself, but you really couldn't understand what he was saying. Your mind was blank. You tried to see him as a murderer, as someone who'd kill three of his friends. As someone who'd lie, as someone who'd fake his tears.

He then faced you.

"Y/N, you believe me, right?"

But then, at the corner of your mind, a memory replayed itself.

"Jungkook, you believe me, right?"

And you saw yourself in him, when you cried and begged to be believed.

You voted Jungkook. Hoseok and Jin voted him right after that.

You turned your back to him like he once did.

Taehyung pressed "skip", not taking part in this.

Three votes on Jungkook, and one skip.

A door opened right under Jungkook's feet and the boy fell to the unknown. He disappeared, and you'd never forget the teary eyes he had when he looked at you as he was falling.

Words appeared on the table, leaving you all dumbfounded.

Jungkook was not the Impostor.

1 Impostor remains

Wait... what?
