TheEvilQueen's video: Once Upon a Time 03x13 Witch Hunt - Emma and Regina trying to replicate the memory potion

SPOILERS AHEAD! DON'T WATCH IF YOU HAVEN'T SEEN THE EPISODE. Regina is trying to replicate the memory potion while Emma is anxiously observing her work with great interest. Regina's attempt at replicating the potion unfortunately fails and gets all frustrated since she can't live in Storybrooke if Henry doesn't remember her. Emma though gets another idea saying they've been running the wrong con. Regina though still not catching on says that she's not well-versed in cons. Emma explains it's an old bail bond's trick. You smoke out the perp by letting them think you're onto them. So if the person who's responsible for this curse thought they were about to make a memory potion, they would want to stop them. They just need to get the word out and Regina knows exactly who to tell. Leroy comes in barging into Granny's Diner with news that Emma caught Regina in the office who was close to making a memory potion. The real culprit *cough* Zelena *cough* then sits up and leaves the diner. Emma: Well, do you remember? (Regina angrily throws the flask into the wall.) Emma: Either that wall did something to you in the past year or I'm gonna say it didn't work. Regina (sighs): I must have missed an ingredient.
