Arthur was just about to say the name when Gwaine spoke up.
"How about this..." he gasped, in between short bursts of pain, "I know where Merlin is. So if you want him that badly, you'll take me and leave them alone..."
Morgana looked down at him.
"Ha, You think I'm going to fall for that?" then she paused, considering, "although... you are one of his best friends... so maybe..."
An idea struck her and she laughed.
"Very well, change of plans. I take you, and if you fail to tell me where Merlin is hiding, you get to know why it is a bad idea to lie to me, then come back and ask again, only I won't be so nice about it..."
Gwaine groaned,
"I had to open my mouth..." he murmured, whilst concealing a wink to Arthur.
Arthur got the message, 'dont interfere'. He sat back, cursing himself. Cursing Morgana. Cursing Magic in general.
Morgana noticed his clenched muscles and grinned.
Arthurs discomfort solidified the deal.
"Very well." she snapped her fingers and a pair of guards hoisted Gwaine up, dragging him along the passage. They shoved Percival back into the cell, paying no attention to the struggle he put up, weak as he was from the demon cuts he had. Morgana chuckled once at the anger on Arthur's face and turned away, walking up the passageway, her black dress trailing behind her.
Before long, she was out of sight and earshot and Merlin stepped out of the shadows.
He looked as angry and dismayed as Arthur felt, and took no time in blasting the locks.
Within minutes, he had unlocked all the cells and healed nearly all of the demon wounds. After being healed, they head down the passage at the other end of the dungeons, following Gaius to the large chambers. The energy it took to heal them combined with his own injury meant that he had to drink from the waterskin almost immediately, and then again in order to heal the last few.
He had only three left to go when the knight who had spoken out against magic before shoved him away. He lost his balance and crashed into another of the knights, who grabbed him and stopped him from falling.
Merlin turned to the knight, a questioning look in his eyes, already knowing what he would say, and sure enough,
"Dont even think about it." he spat, "Im not going to be touched by your kind. You're all unnatural and these men are idiots to trust you."
Merlin turned to Arthur, exhasperated,
"Arthur... If I don't..."
Arthur cut him off,
"Heal the other two, Its his choice."
Merlin was surprised as the cold tone in his voice, but did as Arthur had said. A few minutes later, they were all crowded in the tunnels, with no traces that they had even been there aside from the damaged locks.

Merlin and Gaius told him their plan, and Arthur agreed with them. Half of his knights would go to the lower town, to help protect the people and to stop the spread of panic, though they would have to be well hidden by the time the alarm bell sounded. The others would make their way up through the twisting passages that led to the different areas of the castle, creeping through the castle and situating themselves in different places for Arthurs signal. The only ammendment to the original plan was that instead of just having to rescue Gwen, they would have to help Gwaine too. Within minutes, the passage was empty aside from Arthur and Merlin, Gaius having accompanied the men through the castle, helping direct them.
Merlin and Arthur made their way up through the castle, heading for the passage that came out in near the hall. They crept up to the balcony, narrowly avoiding being seen twice by patrols of guards, and peered over the edge.
Arthur whispered to Merlin.
"The last time we did this, I looked down as Morgana took over Camelot..." he sighed, "I'm not sure which is worse..."
Merlin pointed down at Morgana, who was sat in the throne, and Gwaine who was kneeling in front of her, blood dripping onto the floor.
"Well, she wasn't going to kill your father right at that precise moment... though you do have a very talented sorcerer watching your back this time..." he whispered back, his focus on Gwaine.
"Fair point... though I had that last time, didn't I?" Arthur whispered back, smiling.
Merlin shook his head.
"You know what I mean..." ha said, before realising that Arthur was joking with him.
Arthur kept up the smile at the indignation on Merlins face, but was distracted by a cry of pain from Gwaine. His expression turned to one of anger.
"Are you sure about this Merlin? If she catches you..."
Merlin nodded,
"Gwaine is one of my best friends, Arthur... He has helped me so many times... Im not leaving him to die..."
"Then lets go." Arthur replied, "Good luck..."
"You're the one who's gonna need it..." Merlin joked, "Im not there to drag you from whatever trouble you land yourself into this time..."
Arthur snorted.
"We'll see about that." he answered, and crept back from the balcony, heading off to complete his part of the plan, leaving Merlin to stare down, with loathing, as Morgana tormented Gwaine.
He backed away and crept down the back stairs.
Time to move.
