Executive producer Edward Kitsis said, "Every part of her is fighting her dark urges," adding,"What happens when [the darkness] mixes with the lightest magic of all, and will Emma have the strength to fight it?"

Meanwhile Adam Horowitz said, "How a 'Dark One' manifests is specific to each person who takes on the mantle. Emma will have her own unique spin on what it means to be a 'Dark One'."
