After exploring the house and getting a basic idea of where the bathrooms and such were, they all were stumped. Would they spend 7 days walking around in a house that seemed completely empty and ghostless? Gaz, who had appeared a little interested before, gave up and sat down on the couch in the main hall, where she began to play her GameSlave. Zim also sat down, but in a second Keef was right next to him.
"So buddy, did you see anything cool? We didn't find anything except that old rat nest. I hope we don't see any ghosts. They really scare me, but I know you'llllll protect me won't you best bud? Dearest friend? Fav-"
"Oh, shut up!" said Dib, "He is an alien! And he is just going to use you in his eeeeevil, alien plans. He will probably lay eggs in your stomach and-"
"How dare you insult my best friend! You're the alien, CRAZY!"
"Someday I'll be remembered as a hero for saving the Earth from that..."
Zim rolled his eyes. They were so annoying. While they were engrossed in the fight, Zim got up and left. He walked down one of the hallways he had inspected before. He knew he was not supposed to search around the house alone, but he did not believe in this ghost stupidity. He was, however, careful to remember exactly where he turned so he did not get lost. He had been walking for about fifteen minutes when he heard it.
"Please let me out!"
Zim stopped dead in his tracks. There was nobody else in the house, was there? That was definitely not anybody he knew.
"Help me! ANYBODY?! LET me out!"
Zim took off his wig so that he could hear better and followed the voice. After a little bit of pacing, he came to a door. He could hear someone clawing at the wood on the other side of the door and yelling.
"Is anyone there?" asked Zim.
"HELP! Oh PLEASE help me!!"
Zim took that as a yes, but he debated on whether or not to open the door. What if the human on the other side was dangerous and was in there for a reason? He already had enough problems with the others, and this one sounded like an adult.
"OH PLEASE OPEN THE DOOR!!! OH PLEASE HURRY!AAAAHHHHH-"
Zim opened the door. He nearly fainted.
Nothing. Nothing but air. The room was completely empty. It was nothing but wooden walls and a wooden floor. But what was even more disturbing was the fact that the door had no doorknob on the inside. Once you got in, someone had to get you out.
Was he going crazy? Zim closed the door and locked it with the key they had been given. A room that you could not get out of should not be opened. He started back, but kept looking over his shoulder incase something dangerous popped out of the one-way room, which was (Zim hoped) impossible. But after he started walking away he heard crying coming from behind the door. This time the voice was different, and familiar, but he could not place on who it was.
"sobPlease...sniff...let me out Zim...I want to get out...It's so dark...I can't see...please help me...Zim...Zim, it's so dark...I'm so scared..."
Zim ran the rest of the way back.
A pale faced Zim returned to the hall. He had barely remembered to put his wig on before he went in.
Dib was the first one to notice his presence.
"What happened, Zim? You look awful." Zim sank into the nearest chair and managed to say, "I thought I heard someone in one of the rooms, but nothing was there." Gaz shrugged.
"Maybe you just imagined it." She said.
Zim shook his head and said forcefully, " I am SURE I heard it. It kept yelling at me to let him out of the room, and it knew my name."
Zim brought them to the room. It was just as he had left it: empty. But Zim still hated that room. It was terrifying, not to be able to help someone who was begging you to. It made him feel so weak. It was decided to keep the door locked.
