Before First Curse
Before Third Curse

Emma summons Nimue with the dagger. After a confrontation where Nimue tries to force Emma to kill Merlin, Emma manages to regain control and forces Nimue to yield the ember to her. ("Nimue")

After Third Curse

Emma is in her basement, when all the previous dark ones come to watch the reigniting of Excalibur. Emma then gets Nimue's ember and puts it into a round, stone looking plate and ignites it, then turns it into a ball of fire, which then turns into a small light. She then gets both the Dark One's Dagger and the broken Excalibur and puts them both into the light, which makes it whole again.
