"John dear, could you help your father with his project before he hurts himself?" "Yes mother!" he replied. He chuckled to himself. His dad was always working on some project; he was a scientist at heart after all. He walked down into the basement, curious as to what it could be his old man was working on this time. When he got to the bottom of the stairs, he saw something underneath a tarp. Thinking of it as an old project of his dads, he turned his gaze, focused on the workspace before him tinkering on something was his father. "Whatcha working on Dad?" "Oh!, John! You startled me! Don't do that."
"Sorry dad"
"It's ok.. uh, you want to pass me a screwdriver?"
"Sure!" As John grabbed the tool, he noticed his old US Army figure was in shambles, and it looked as if the AI chip was torn out of it's socket. "Hey erm, Dad? Where did the AI chip from my old Army guy go?"
Upon hearing this, his dad turned around, grinning ear to ear. "Son, you remember how I wanted to make us our own Servant? To help your mother around the house? I decided to use it since those newer fancier ones are pricey. It's almost done"
John then realized what lay beneath that tarp. The AIs Body
He then pulled off the tarp, giving the body a look over. It was spectacular. It was close to an actual human being in every way. He then took a few moments to collect himself.
His mother was diagnosed with leukaemia several years prior, making her daily chores difficult. His dad helped her when he could, but between his projects, it was also getting difficult for him. John could help, but his job was too good to give up. They would have hired someone already, but after hearing how many were thieves stealing behind their employers back, they decided against it. They were also pricey, at 50k a month and they didn't have that kind of money, even with Johns job.
He asked his dad when it'd be ready
"Soon enough. Say, an hour? I just need to program the AI, set up rules, all that mumbo-jumbo"
"Ok" When he heard this, John was pretty excited. His mother could finally have some assistance. He then decided he'd better go to work, letting his dad do his thing.
7 Hours after
When John pulled in, he couldn't contain his excitement. What did Dad name this Servant? What were this AIs capabilities?
Walking in, his parents were in the living room, also visibly excited. "John! Meet Gregory!"
The AI Servant walked into the living room at that same moment. "Hello John! My name's Gregory! It is a pleasure to meet you!" Observing the AIs face when it spoke, it was incredibly life like, and his voice... it was smooth and calming, like an actors voice in the 50s.
"Hello Greg!"
Right when Greg was about to respond, John woke up. A single tear trickled down his face, realizing it'd all been a dream.
In reality... in reality the AI was almost as nice. One night, when his parents were sleeping, the AIs security firewalls failed, and it killed them in their sleep. It was out there somewhere, probably killing more, for sport.
