I'm going out on a massive limb, but what if the serum somehow gets used on Gold and a fully evil SerumRumple emerges. This could potentially be the hooded figure that kills Emma in her vision (the figure used dark red/maroon smoke to vanish her sword, Rumple has maroon smoke).

Even if it isn't SerumRumple, I still have a feeling that a Serum character could be the death of Emma.
