Sierra had been searching around through all the places that weren't locked, she had to find this portal gun. Where could it be? She wasn't sure, Wheatley didn't know where it was, and Space just kept muttering space to himself. How would she know when she found a portal gun?
Sierra was just about to give up, when she eyed the vents, maybe she was small enough to crawl through there. She could see if she could find a portal gun and then bring it back. She fit very easily into the vent. "Okay, remember, find the portal gun, and come back and maybe we can get through," Wheatley said. She spent her time searching for that portal, when she spotted a weapon-like item, maybe that's the portal gun, Sierra thought. She opened the duct and grabbed the gun. She then crawled her way back to Wheatley and Space.
Sierra held the portal gun and fired away. She shot two portals, orange and blue. "Wow! This is so cool," Sierra said going through the portals. "Yes, yes, but now if you want to go in you have to shoot the portals and have to be able to get inside," Wheatley explained. Sierra thought for a while, she wasn't sure what to do. She walked around, there were some areas that were higher than others, she couldn't get up there easily, at least, without a portal gun. She shot a portal above those areas and she was able to enter other areas instantly. She explored around a lot more, but then Wheatley started panicking again, "okay well, maybe it's best to head back, I really, really don't want to face her," he said. "Stop worrying, we'll be fine, be a little braver," Sierra said. Wheatley just sighed.
They entered a big room, broken parts, and big pieces of metal everywhere. "What happened here?" Sierra asked. "Your mother," Wheatley said, "she killed GLaDOS and tried to escape the testing chambers, and pretty much destroyed the place." My mother did this? I don't believe it…
After a few minutes of walking they spotted the A.I., and hid. "There she is, okay well we had our fun, so lets go now," Wheatley whispered nervously. Sierra just glanced at him, and turned back to GLaDOS. "So what happened after my mother killed her?" Sierra asked. "Well, after that I tried to help your mother escape, and ended up taking control, and didn't really do a good job at it, so then GLaDOS regained control, and I was shot into space," he explained. She didn't really understand much, but she got what he was saying, GLaDOS hated her mother, therefore she would kill Sierra. "By the way, I never did ask, what are cores anyways?" Sierra asked. "Cores are what are attached to GLaDOS in order to improve her, unfortunately, there are corrupted cores, such as what Space is," Wheatley explained. "Are you a corrupted core?" she asked. "No I was made and programmed to, well, slow down GLaDOS, she was too smart for the scientists, so they had to create me in order to keep her from hurting anyone before she got too smart," he said. "Sooo…you were built to be a moron?" she said. "I AM NOT A MORON!" he yelled, but then quickly went silent.
They knew she would've heard them because of Wheatley yelling. Shoot we're so dead Sierra thought. She couldn't think up a quick enough plan before she already found them.
Sorry so short promise to make it longer next time :)
