Sorry if another discussion about this was started, but I couldn't find any.
When Bigby was at 207 room, in the wardrobe there was an envelope with pics incriminating Crane. If it was him that made that with Lilly, would he be so dumb letting evidences like that at the crime scene? I don't know, maybe it wasn't him letting those pics there, but it sounded a bit amateur. I can't believe that someone so intelligent like Crane would do that.
Well, perhaps I may be misunderstanding all this, but that really got me thinking.
