Mystic Falls Past.

"You're using dark magic." Melissa said

"It's not dark magic. It's expression and I need it." Bonnie said

"It's heavy stuff Bon. You don't know anything about expression. You don't know what it could do to you. I'm gonna tell the others." Melissa said

"I'm sorry. But I can't let you do that." Bonnie said

"Just watch me." Melissa said

Bonnie impales Melissa with a staff as she falls down.

"Oh god what have I done. (Bonnie moves the staff with her mind. She's shaking Melissa.) I'm sorry." Bonnie apologize

Melissa was healing. She wakes up and gasps and she gets up.

"You can tell them yourself. Just leave me alone." Melissa said


Camelot.

Six weeks ago.

Outside Granny's.

Birds chirping.

"Melissa. Melissa. Melissa, there is a way to make Excalibur whole again. Will you come with me today so we can get what we need? It's not far." Merlin said

"What is it?" Melissa asked Merlin

"A spark from mankind's original fire, the Flame of Prometheus. Its heat forged Excalibur, and that's what we'll need to put it back together. So will you come with me to collect the spark? We'll be back by nightfall. When we get there, we will need to deal with the first dark one." Merlin said

"The one who wore the mask? The one who killed the woman you love?" Melissa asked again

"The very same. This is not a trivial task." Merlin said

"I was seeing Rumplestiltskin. It was like a hallucination. I just got rid of him. And now you want me to let another one in?" Melissa asked again

"Yes, and not just anyone. This is the first dark one, the original, the one from whom all the evil that followed was born." Merlin said

"Will we win?" Melissa asked again

"I see two paths for our journey, Melissa. On one, you push Emma out of the darkness. But you resist the darkness and we succeed. The other, you succumb to the darkness and I do not return. I die." Merlin said

"No." Melissa said

"Even immortality has exceptions. A dark one does have the power to kill me." Merlin said

"But they won't even be there. Not really. (Merlin looks down.) Me. If you died, then it would be me." Melissa said

"If I die, it means that the darkness will stained your soul." Merlin said

Jeremy frozed and his sister sees an arrow on him. Melissa runs towards her brother as she catches him.

"Jeremy. (Melissa put the pressure on him.) Oh my god. Oh my god. Don't die on me." Melissa said

"If you can do it for Robin. Then you can do it for Jeremy." Emma said

Melissa uses dark magic to heal her brother.


Outside Granny's.

"We're going to get this spark thing, and then I'm working my way back to you guys. (Melissa kissed her husband.) I'll come back for you." Melissa said

"We will always find each other." August said

"Always. I just hope that with a bit of luck, we can put Excalibur together tomorrow, and then no more darkness." Melissa said

"Be careful." August said

"You know I will." Melissa said

"It's time." Merlin said


Forest.

"When I was seeing Rumplestiltskin in my head, he said he would only be with me until I embraced my dark magic. So recently, I've been thinking maybe not seeing him, maybe that's a bad thing." Melissa said

"I've seen you used dark magic to heal your brother." Merlin said

"I had to. We promised that we would look out for each other. And if I dig deep down... the darkness is winning." Melissa said

"There is hope, and it's up there." Merlin said

"That's a whole lot of up." Melissa said

"We can make it. The question is, will I come down? (Birds chirping.) This structure marks the end of Prometheus' theft. The stolen flame burned on for a great while... Long enough for Excalibur to be both forged and broken here. This is where the first dark one killed Nimue, the woman I loved." Merlin said

"What happened to the flame?" Melissa asked Merlin

"The first dark one took it and still possesses it in the form of a single ember, with the spark deep inside." Merlin said

"So that's what I need to get. Okay. Bring him on. (Merlin hands Melissa the Dark One dagger.) Regina let you take this?" Melissa asked again

"I didn't ask permission. You need its power to talk to the first dark one, to reach all the way back to the origin of dark magic." Merlin said

"It's buzzing, like...ants crawling up my arm. Is it safe?" Melissa asked again

"Of course not. You have dark magic. Your power is totally unchecked, and I've just handed you the power to kill me. Now...call on the spirit of the previous dark ones." Merlin said

"Take the right path. (Breathing shakily) It's just in my head. It's just in my head. It's just in my head." Melissa said

The Dark One dagger scrolls back through the names of all previous dark ones. A figure in a robe and mask appears before Melissa.

"You did it." Merlin said

"You can see him, too?" Melissa asked again

"Yes. And it's not a him." Merlin said

Melissa looks at the Dark One dagger, and the name on it is "Nimue".

"Nimue." Melissa said

"Yes. I'm Nimue. And you are Melissa. How pretty, the first dark one and the newest dark one standing as sisters." Nimue said

"Sorry but I have siblings. And you're not one of them. It makes sense that you killed the woman he loved because you killed the woman you used to be. (Melissa looked at Merlin.) You didn't tell me?" Melissa asked again

"I did tell you. The creature over there is the first dark one. It's not the woman I loved." Merlin said

"It's been a long time, Merlin." Nimue said

"I've thought of you every day." Merlin said

"And now, on your last day, I'll be your last thought. How poetic." Nimue said

"And you're being a bitch. You loved him. Yet you choose darkness." Melissa said

"Even when you love someone, you have to say, "No, this is mine. You can't take it away from me." And if they don't listen, if they try to stop you from being you, then you have no choice. You have to kill them. Oh...(Merlin groans.)...and you're doing this...(He's choking.)...because we are one and the same now, all dark ones, and we must destroy the threat to us. We must destroy Merlin." Nimue said

"Margaret, please." Merlin begged

"It's... not me!" Melissa said

"Finish the job!" Nimue said

"Don't listen!" Merlin said

"He wants you to make a sword to destroy me, to destroy us." Nimue said

"You can control this." Merlin said

"Don't listen to him! He doesn't understand what you and I do. He doesn't understand the power. If you don't kill him now, you'll go back to being powerless." Nimue said

"Killing is the dark path. Let the light win." Merlin said

"Kill him! Don't go back to being nothing!" Nimue said

"I was never nothing! And you're just a bitch that left him. (Nimue gives her a surprised look.) The power you have I don't need it! I am a Petrova and a Gilbert. Daughter of Isobel Fleming and John Gilbert. I'm a sister to the Gilberts and Emma Swan. I've a husband, a son, a daughter, and friends. Everyone who cares about me doesn't think that I'm a nothing. I am a traveler witch. And Now I am going to take that ember from you." Melissa said

Nimue gasps as she's breathing heavily.

"The spark you need is in there...but the sword you will make has more than one use, and I am not dead yet, girl. You know where to find me when you want me. (Nimue touches Melissa's forehead.) I'll be right in there." Nimue said

"You did it." Merlin said

"I did. (Melissa breathes shakily.) What happened after she turned into the dark one?" Melissa asked again

"First, my Apprentice and I made sure the sword would be safe. Then, I created the dagger. I tethered her spirit to it so I could control and prevent her reign of terror. But eventually, she got it away from me." Merlin said

"She put you in the tree. She wore the mask then." Melissa said

"Yes. She took that mask from a man who did her great harm. It's easier to live with the darkness if you can dress it up as vengeance." Merlin said

"Your heart was broken, but now I know...Nimue loves you still. It's all twisted up, but I felt it." Melissa said

"Thank you. (Merlin inhales deeply.) That means a lot to me." Merlin said

"We need to keep going and to find the other half of Excalibur." Melissa said

Melissa turns and Merlin is gone.


Storybrooke. Present.

Melissa's Cave.

"Go on. It's time." Rumplestiltskin said

"Why couldn't you just leave me alone?" Melissa asked Rumplestiltskin

"Well, how could we? We're here to witness something historical." Rumplestiltskin said

"Rumplestiltskin's eyes are fine to look through most days, but I wanted to see this myself." Nimue said

"You tried to keep me from doing this." Melissa said

"Back then, there was a chance that you would use Excalibur to cut away the darkness, but now you can douse the light instead. We are proud of you...all of us." Nimue said

"All of us. All of us. All of us. All of us." All Dark Ones said

Melissa sees the name written on Excalibur.

"Merlin. He told me not to do this." Melissa said

"Take the power." Rumplestiltskin said

"Take the power." All Dark Ones whispers
