Emma (Savior) takes Serum and we see The Dark Swan
I don’t know if this is possible unless Emma has some residual darkness left in her. Didn’t her parents perform the work of the serum by transferring her darkness to Lily?
Maybe Rumple and Belle could both take the serum and they could pair off – spinner Rumple with Belle and DO! Rumple with Dark!Belle. Seems like the simplest solution to their problems. Although – if Belle took the serum, would both her halves be pregnant?! Would they give birth to light and dark babies? Or maybe she reintegrates herself before giving birth and is left with twins – one dark and one light. Then we’d have the good vs evil fight of the next generation already set up!
