"Is that your knees again?" Arthur asked, no smirk on his face this time. He walked forward and lifted the heavy plank off of the door and passed it to Merlin.

"If I need a servant in the next life..." Arthur said, "Don't ask me" Merlin replied. They laughed as Arthur pulled out his sword, turned and left the room. Merlin quickly placed the heavy plank back down and turned to Morgana.

"He's not going to survive out there" Morgana said, a worried expression on her face.

"I know" said Merlin.

"We've got to do something!" Morgana said, panic rising in her voice.

"I know" said Merlin again.

"You know something Merlin don't you?" Morgana said; worry etching back onto her face.

"Morgana I..."

"Tell me Merlin, I need to know...what is it?" She said more quietly.

"For the spell to work it must have a living presence to keep it activated"

"So what do we have to do to it?" Morgana said worried and now confused.

"Destroy it, it has to killed or Morgause has to stop it herself"

"She won't do that, what's the source?" Morgana said getting frustrated.

Merlin just opened his mouth and looked at Morgana, then back down. He couldn't tell her, her just couldn't.

"Merlin, tell me!" Morgana replied, she knew he knew and wasn't telling him, it was making her angry.

He looked up at her and stared into her eyes, they were full of worry and frustration. But beneath all of that, she was just scared, that scared little girl that got terrified every night after a nightmare. He looked quickly down at the floor and whispered so quietly that she only just heard him. "You"

Her mouth slowly dropped and tears gathered in her eyes as she stared at Merlin's bright blue eyes.

"No, it can't be, she wouldn't..." She trailed off the tears flowing freely now. Merlin pulled her into him as she starting shaking. He didn't know what to say, so many things were running through his head. Morgana's legs then gave out and she fell to the floor sobbing onto Merlin's shoulder. It couldn't be, it wasn't possible, why would she do this, she trusted her. No Merlin must be lying. She looked up into Merlin's eyes and said: "You're wrong, she wouldn't do that, I know it"

"Morgana she would and she has, you don't know her, you don't know what she's capable of"

Morgana opened her mouth to retaliate but as she felt the words sink in she knew he was right, she didn't know her or what she's capable of, not really. Whereas Merlin, unbelievably even though the idiot he was he was normally right, he is right. She knew now, either she must die or the whole kingdom must die.

"Just do it, get it over with, please" She whimpered as she started shaking again, not looking it at Merlin, she knew she wouldn't be able to let him do it if she did.

"No Morgana, I can't..." Merlin stammered, he hated this just as much as her, maybe more.

"Please" She whispered so quietly as she closed her eyes trying to regain control of her shaking body.

"No, I cant...you, you're going to talk to Morgause" He said, thinking the words as they came out.

"What? What are you talking about, why?" She said opening her eyes and bringing them up to look at Merlin thoroughly confused now. Why couldn't he just kill her now rather than trying to make her suffer.

"Be, because you can change her mind" He said, knowing if she did he could avoid doing the thing he dreaded the most.

"How can I? She wants Uther dead and his reign to end, what does it matter to her if I die in the process, why would she make me her source otherwise?" She replied getting angry at him stalling for time now. They didn't have time, any minute now Arthur could die and she couldn't hold herself responsible.

"Because" Oh no Gaius and Uther (if he found out) would kill him for saying this but isn't that what Merlin did best? "Because" He sighed and said "Because you're her little sister, she would never kill you"

Morgana's mouth just dropped open, she was utterly stunned, and she never thought Merlin would say that, or people would know about that without telling her. A hundred thoughts started racing through her head: Is that why she thought she recognised her? Is that why she trusted her so easily? Is that why she had been so caring and gentle to her? Is that why she said she was so pleased to hear her say she was on her side? As much as she hated to admit it, it did kind of make sense. But then why did Morgause lie to her and not tell her she was her sister? Then the tears came again.

"Morgana, I'm so sorry, but you HAVE to talk to her, it's our only choice, the only way to save everyone" Merlin said, he felt really bad, but equally so sorry for her, he would hate to be in her position.

Morgana looked up and back into those bright blue eyes through her wet glistening green ones. She knew he was right, if she wanted to save her and Arthur, everyone in Camelot, even her worst enemy Uther she had to talk to her 'sister'. She got to her feet still slightly shaking her face wet with tears and sighed. Merlin took hold of her hand and squeezed it slightly, as he led the way to the door. After taking off the wooden panel from the doors he opened it, to reveal nothing. There was nothing there, Arthur and the knights had vanished and he had no idea where Morgause would be. He looked to Morgana whose eyes were closed and her face filled with utter terror. He had never seen her look so scared before. He gave her hand another squeeze. She didn't react so he took her out of the room out into the corridor, beginning their search for Morgause.
