I don't own Scooby Doo that belongs to the creators.
23-yaer-old Sammy had no right to call Kenneth his brother anymore, after what he did he had no right to belong to the family. He betrayed not only his trust, but his loyalty to him and Scrappy's too. They continued to watch as their younger selves body were trembling, they had one thing in mind destroy Kenneth . He caused this to happen, and for what money. Money is poison; it's what drives this world to madness they thought.
16-year-old Sammy heard the bell ring, Scrappy and him walk sloppily up the stairs of the basement, and Sammy opened the front door. They saw his brother Donnie stand there with a worried expression on his face, Sammy and Scrappy couldn't hold him themselves anymore Sammy jumped on his brother, hugged him, and toke out all the pain and regret he held up inside, Scrappy howled tears striking down his face.
Donnie came inside, and saw the basement door opened. Once little Sammy settled down, and fell a sleep from crying too much. Scrappy and him walked down the stairs of the basement. As he went down he knew from the blood and pieces that someone has not only murdered his mom, dad and Scooby, but also copped them to pieces. He found no evidence to who did this. He was sick to his stomach, he ran up stairs and straight to the closest bathroom.
23-year-old Sammy and Scrappy ran up the stairs, out the door, and to the time traveling car. They finally knew who caused all this misery, not only to them, but Donnie too. If it wasn't for Kenneth , they would be smiling and laughing. They wouldn't be sleeping with a face full of tears, and a sick feeling in there organs. Kenneth was the cause, and he was going to pay. No one will figure out that they are going to destroy Kenneth's future, and his case will be unsolved just like Scooby and his parents. But first they had to go back to their time to gather up some things they need for their plan to work, they headed to the car and left.
