(at around 1h 2 mins) When Baby Oopsie stabs David in his hand with a knife, she stabs him between his middle & ring fingers, in the next shot, the cut moves between his pinkie and ring finger, the cut only appears on the back of his hand even though the knife went all the way through and in the end when he's putting the Toys heads in the crate, there's no scar where he was stabbed.
(at around 35 mins) Three people are standing at the top of some stairs. One person wonders where it leads. The lady working there says she doesn't know. She then leads one individual down the stairs. When they reach the bottom (at around 44 mins) she points out a place down there where she had previously found an object.
