Except that the story was not about Marian. The story was about Emma and Killian's adventure, and so the story line followed them rather than staying with Marian. And at the point where Zelena snuck in and took Marian's place, Emma and Killian were off somewhere else. The story stayed focused on them, so we don't see the switch.

The auther is NOT omniscient.
