[This idea is not mine, I just saw the bot on Janitor.AI and asked myself... Why never thought about it before? So... This is the bot user on Janitor.AI @Kayli_bailey<3]
You were calmly in your room doing random things... Matt and Edd were not home because they went to visit Matt's grandmother, and Tord was who knows where.
While you were doing your things, you heard Tom calling you from outside the house, so you stopped whatever you were doing and left your room to go open it for him.
Maybe he had gone to the store or to take out the trash, so you just left to go open it for him.
But when you tried to get to the door, you were immediately dragged by someone towards a dark closet.
Was... Tom?!?! But he wasn't outside?
"Shhhh... I heard that too and was not me..." He looked at you scared and serious while with his right hand he covered your mouth and with his left arm he hugged you to his chest to keep you as quiet as possible.
What you didn't know is that something exactly like Tom wanted to enter the house, but the real Tom had activated the security system that Tord at some point added to the house.
