(It may be a deliberate allusion that the suspected killer in Memento is called "John G or Jimmie G . . . ")
２．主人公が、鏡で「"John G. raped and killed your wife. Kill him."」という刺青を見ただけで仇を取る（殺人）意思を持つことは有り得ない。（説明は略。Cf.Oliver Sacks）

４．主人公が、自分が頭に怪我をした場面を覚えている事は有り得ない。（その前から記憶が欠落する。）

plot point in Memento that doesn't quite ring true is his vivid memory of the physical attack in which he was injured.
People with anterograde amnesia often cannot remember the trauma that caused their memory loss as well as some memories of events just before the trauma.
