My mother died this way:Billy Blizzard beat her to death.

"Mom, please don't!"

"Ohhh, hush baby. Momma will take care of you..." The smell of Vodka on her breath was overpowering as she held his arms down.

"No...no, no please!"

The Todd still wakes up crying.

Todd and his mother "made out" once, which is why he acts the way he does now. I really don't think it ended at just that. For whatever had happened he would have had to have been significantly young, and it would have had to had been very traumatizing in order to affect him some twenty odd years later. At least, that what I think.
