After the Curse
Mary Margaret and Leroy try to sell candles. ("Dreamy")
When attempting to sell more candles for the Miners Day Fair in Storybrooke, Mary Margaret and Leroy knock on the door of a Storybrooke townsperson, candles in tow, the door opens and a skinny man with a carrot stares them down. Mary Margaret tells him that they're selling candles for Miners Day, however, he merely takes a bite from his carrot. The man's wife comes to the door, takes one look at the pair of them, and tells them that they're not interested, before slamming the door shut in their faces (this being due to the fact that Mary Margaret is the town harlot and Leroy is the town drunk). Mary Margaret and Leroy are then seen standing hopeful at another door, which also slams in their faces. Another door slams in their faces. And another. And another. And yet another, all before they can fit a word in edgeways. At the final door, Leroy looks to Mary Margaret, seeming disappointed. ("Dreamy")
Here comes the mob... ("Child of the Moon")
After the curse is broken, Ruby, who was a werewolf in the land that was, worries that she may turn into a wolf come nightfall, due to the return of magic. Her theory is proved correct, and she rampages through the woods one night... which just so happens to be the night of the town mechanic, Billy's, murder. Spencer, Charming's adoptive father, wrangles up a mob to attack the sheriff's station where David is keeping Ruby, and part of this mob is the wife of the skinny man who once encountered Mary Margaret and Leroy selling candles. She follows the mob as it goes in search of Ruby and witnesses King George try to execute her, however, David and Granny show up just in time to save Ruby, and expose to the people that Spencer killed Billy to try and prove that Charming is not a fit leader.
