Now, make a hiatus in your end and think about a break of ten-twelve years. That kind of event doesn't really make people closer, you know. Amrod and Oilossë never played cards together since this day, never talk either. But one day the artist wanted to take some news from her old friend and went into her apartment. The code was the same so when she wasn't answering, he solely get in. Nothing had changed except the fact that it was even wealthier than before. She could have move to a bigger place, but this apartment was the last memory from Ulwarth. Certainly the raison why she stayed in.
Suddenly, an "hello ?" came from the other side of the room and Oilossë arrived. At first he thought it was only her robot, but her face had changed and the time did his thing. She wasn't a teenager anymore, but a strong lady. Still, she was pretty.
"Oilossë, I'm sorry to come without telling you in advance but I was walking in front of the building and … All the years came back into my mind, all our memories and I wanted to see you one more time" he said, opening his arms to hug her.
"Happy to see you too." She answered, coldly.
"I'm sorry , I though after the … you know …"
"What ?" Still cold.
"Don't force me to say it please, but Ulwarth ... We both loved him at our way. And he's gone because of us. Nothing of that should have happened."
"You are right. It is true." Frozen.
And now you should know what's going on. Obviously, when you kill someone you do remember. Why Oilossë wasn't remembering that ? Maybe because that wasn't her ? Now the robot knows their secret. Never ever trust a clever robot, every movie about robot could tell you that. Still, people never learn !
Thus happened what should happen, the robot started a riot. She didn't want to do humans stuff instead of them anymore. They need to do what they can do. She wanted to live her life, find friends robots and hang out with them, not cleaning the house 24/7 for a stranger whom strangely looked like her. Besides, robots have emotions too, they are not solely electricity and cables, what everyone seemed to think. One top of that, it wasn't fair : she was aging and not her humans. Robots are not supposed to age instead of humans ! After some quick searches on her database, she found the best way to kidnap someone without leaving any marks or clues.
One night, while she was on a deep sleep, she put on the human's face the chloroform she had bought a month before (don't arouse suspicions, you know). When she rested assured that she wasn't going to wake up, she took her body between her old mechanic arms and brought her into the cellar of her own apartment. Even if she lived in a building, she had her own cellar, where she never got a foothold. Statistically it was the safer place to hide a corpse : on his own house, where no one would think to look. Moreover, only a few people knew she had a cellar. And the best part of the plan is that no one will know she's missing, because the robot will BE Oilossë. Simply genius.
