I might have gotten distracted at one point and missed the explanation for this. How did Rocky get the safe combination? I know she was in the closet but wasn't she down below and out of any vantage point to see the guy enter the combination?
That................is how she got it. She watched the digits being put in and memorised. So...................................it is one of those "just go with it" scenes. But yeah they specifically had the camera angles to where she saw the code put in for when he was closing the relocking the safe. She saw the code after he locked it because it stayed on the safe screen for a couple seconds before it disappeared. It was only 4 digits.
Movies. Lol. The writers had to do something to make it able for Rocky to get into the safe. Lol. But no it wouldn't make sense especially for the owner of the safe being blind. But movie writers, just chalk it up to that.
