Question: In the first film, when Jacob is jabbed in the eye before falling down it's his left eye, now in part 2 it shows he's missing his right eye instead. Am I correct, or am I confused, or is it shown from a different angle?
Answer: It was our left and his right in reality, he was facing the opposite direction.
No, he was stabbed in his left eye. When facing the camera, the pipe is on the viewer's right which is his left.
Answer: In the first movie Jacob Goodnight was stabbed in his right eye with a metal pipe.
It was his left eye he was stabbed in.
