Just for reference... from "what about bob" you find out that Harry did know his mother but she left at an early age cause she couldn't take his father's constant moving around.
You're mistaken. It's sad (I have no life) but I have this episode, line for line, memorized. She did not leave Harry and his father. In fact during the argument with Justin Harry asks him if he's the one who killed his mother. 'Did you kill her?!' 'No. I. Did. -Not-!' Dresden then looks to Bob and asks 'Is he telling the truth?' Bob stammers and then notices the piece of broken table flying for Harry and shouts to warn him. Harry drops on the voodoo doll, Justin dies.
Please don't misquote me.
I don't like finding out months after the fact that someone has been misquoting me to claim the show version of Harry's mother was alive and or that Harry knew her. No. He knew about her. In What about Bob Harry asks Bob if he knew his mother. This is because Harry, himself, has no actual memories of her. Bob replies that he did not know her very well but knew her well enough to know she was a force to be reckoned with.
When Harry's father gives him the shield bracelet in Birds of a Feather Harry asks 'Why wasn't she wearing it?' (he's talking about when she died) and Malcolm says 'I don't know.'
I never claimed the show version of Harry's mother left him and Malcolm and I would fiercely argue anyone who would claim such a thing. There were only twelve episodes but certain things were firmly established for it's mythos.
