re: Dark S3 Discussion (spoilers after OP)

I just finished and need a lot of time to think things through. I do have one question and haven’t seen anyone mention it yet.

Why does Alt-Martha’s scratch under her eye change from left eye in one world to right eye in the other world? I know things happen differently in both worlds but that scratch only ever happened in one world, after she had died in the other. So I can’t figure out why it jumped from eye to eye. When I first noticed it I figured it was a mistake. But then it consistently happened. It just doesn’t make sense being that it’s the same Martha jumping from world to world, her scar shouldn’t be changing because of that. Did anyone else catch this? Maybe it was just a subtle way for us to keep up with what world we were currently in.
