Plot twist: Emma goes dark, but it turns out that she’s very much her father’s daughter in this regard.
So Darth Emma always drives at 5 mph over the speed limit, and puts the spoons in the fork compartment of the cutlery drawer, and hides David’s car keys in the refrigerator, and doesn’t rinse her dirty dishes so they’re harder to clean, and takes ages at the checkout because she insists on digging out the correct change
and Snow is annoyed because Emma lets baby Neal have far too much sugar when she babysits (“No I didn’t!” “Emma I can see the candy wrappers” *poof* “… what candy wrappers?” “ugh”)
and Henry is embarrassed because he’s thirteen and Emma ruffled his hair in public (“Mom!” “Muahahaha, kid!”)
and Killian is upset because she referred to the Jolly Roger as a sailboat (“It’s a ship, Dave, and a majestic one at that!” “I know, Killian, I know…”)
and Regina has had just about enough of Emma ringing the doorbell and then poofing out of there before she can answer (“I know it’s her, Robin, but I have no proof!” “Well maybe just lodge a complaint with the… sheriff… damn.”)
and Belle is really sick of Emma borrowing books and not returning them by the due date (“Just get it back, Will, you’re a thief!” “Yeah, but I’m not bloody stupid enough to try and steal from her!”)
I’m just saying, I think it has potential.
