Silent Hill Heaven

I wouldnt see any of the extrsd getting retconned unless a future SH game/canon novel is based on Murphy or any other characters in Downpour. Besides, every SH game contridicts something big or small (mostly small) from the previous titles before it. Consistency withen a long series/franchise is hard, especially when it gets multiple writers throughout.

Mostly I'm considering the fact that Downpour hasn't been out long enough for us to closely examine the implications of all the little details that could contradict the extras. There could be numerous contradictions within this game itself waiting to be brought to light. If ever the facts of the game disagree with a statement from the extras, Tomm's statement makes it obvious which piece of information I should discard.
