I was watching a horror movie on Tubitv and forgot the name of it. It was about a brother and a sister living together. Their mom died, and the brother never leaves the house and everytime his sister goes into town, he will ask her to pick up some coconut water even though he had a fridge full. He also gave his sister’s dog 2 pills. Then the dog tried to kill him. and when his sister got back home, the dog tried to kill her. Then she hit it with a bat?
