i think ive managed!!!!!!
Basicly this is what happend (sorry for lousy english):
So basicly i think it goes like this : if we start the theory from assuming that he killed his wife with insullin , then we ask ; why didnt he end up in an institusion like sammy? So then we can say - well maybe he is running from the cops? Well that is probably not the case because it seems as if the police is not around too much.so then we ask- wait, does the police evdn know? I mean, we didnt saw any policeman around, anyone he knows ( incluedong family members of his ) he didnt step foot in his own apartment even once. And the story about this sammy guy is not here for fun- it is here to explain lennys situation- the rape case git him the short term problems, and afterwards the sammy story was the same as his story :(
