One day when Sandra was 3 and Ted was 5 They were chilling in a room in their house while their parents were in another room doing something else, Ted was with Sandra trying to teach her how to say some words such as Splatfest, Mansion, and his name Ted however Ted smelled something burning and when he looked behind him he saw smoke, holding her sister's hand he decided to peek downstairs and then he saw the whole living room on FIRE immediately he wondered where his parents where and tried to find them before the fire spreed upstairs where he and his sister where located but he never did immediately afterwards he opened the window of the room they were in, grabbed a bunch of sheets, tied them together, and made a rope for them to go down he grabbed his sister and tried to go down not before seeing a shadowy figure walking through the fire before he went down the rope, once they touched the floor they ran to the front of the house were officials were trying to put the fire out Ted didn't know were to go because his parents were the only relatives they knew so he went to the one adult they were familiar with Captain cuttlefish, nobody ever discovered what started the fire and strangely Ted and Sandra's parents weren't found dead inside the house but instead they were found in the back of the house death with their chest burned off in a way that looked like someone blew up their chest off with a bomb or something Ted and Sandra always wondered what in the world started the fire and Ted was always confused about the shadowy figure he saw in the fire and what killed their parents but they never found out... until one faithful day 12 years later...
