There was an episode in S1, (I can’t remember which one someone help me out on that, I think the finale?) in which Snow attempts to rescue Charming when Regina has captured him and has him in a dungeon. When she reaches the dungeon and opens his cell, she realizes that he is trapped in a mirror.
It’s Apple as Red as Blood
“But I’m rescuing you….”
Snow sees Charming through the mirror and it was all a trick
