(at around 10 mins) Emmett and his dog are riding in the elevator and it stops on floor 3, he is clearly terrified with his flashlight close to his body but when the scene changes to the elevator opening up, we see Emmett with his arms down at his sides with a neutral expression then it cuts back to him terrified again with the flashlight close to his body and when it cuts to a shot of his dog, his hand with the flashlight again is down to his side.
