Alastor was in his back garden with his father. His father was abusive and almost always drunken. Alastor was just tidying the garden when his father came out and yelled at him for not doing it right. He hit Alastor across the head with his empty beer bottle. He demanded that alastor get him a new one. Alastor complies and runs inside to get one. However, alastor got the wrong bottle, which made his dad furious. He hits alastor with the bottle again, and again, and again... Etc
