Silent House/Headscratchers


 * When Sarah is hiding under the table downstairs and the killer leaves the room, she sees something which scares enough to scream and run back upstairs. What was it that she saw?
 * With the way that Sarah's father and uncle reacted to the Polaroids found scattered in the rooms, they were likely the pictures of and yet they just shove them in their pockets, mumbling that they're nothing important. Is it really such a casual thing to have accidentally left such photos lying around? Wouldn't that immediately tip them off that  remembers what they've done?
