Let’s take a pause for the moment. The facts are: her car was found in a similiar spot as Ashley’s and also where Emma “stopped” in the end of True North. Gym Teacher/Frederick? was seen stopped behind Kath’s car and he got out. This was the after they bumped into each other at school. There was a plot and conspiracy between Gold and Regina. We know not of any concrete details to the plan except for the key plant, and they expect her to run (MMB) that is. Red found the box with the heart and it had Kath’s DNA and it was not glowing and MMB’s fingerprints are on the box. One of the keys on Regina’s skeleton key ring opens MMB and Emma’s apartment door and is one in the same as the key in MMB’s jail cell. Red found Kath is the alley and she seems at first glance to be disoriented and she’s dirty. She was last seen near woods.
Other than what is factual. There are no other real details to say she was or wasn’t captured. Magic or no magic was involved. It does not take magic to plant a key into a cell. It does not take magic to abduct someone and free them. I’m not saying that was how it happened but does anyone see a point to where this is going? we cannot in our predictions or theories talk for the characters or suggest things to they are fact when it is based on speculation to start with. We should look at what is facts, see what is missing, then see if there is a conclusion or not that the path leading to the makes sense or not.
