Does a fog card stop the Dark Lady from moving, make her jump, or change her path?
The designer answered this in several replies, and the rulebook's fog card option says the cards do not change her movement.
No. A fog card takes the place of a stealth card in her sequence, so her path and step count stay the same and she still passes through that location. The only effect is that you cannot search there that turn. Playing or discarding a fog card does not make her jump either.
