Chapter 4- The Enchanted Cake

Night had fallen on Camelot. Merlin headed toward Arthur's chambers, his mind back in his room. The Doctor said he could come up with something to defeat the Slitheen, but he would have to use this weapon at the last possible moment, for fear of Uther capturing him.

Arthur was just finishing dressing when Merlin walked in. "It's about time," Arthur said. "I was beginning to worry."

"Worried you would have to dress yourself?" Merlin murmured.

"What was that, Merlin?"

"Nothing."

"Anyway, I'm all ready to go," Arthur said. "Come along." He strolled past Merlin, who had to resist the urge to roll his eyes.

They walked into the large dining hall. Merlin took to the back with a few of the other servants while Arthur walked to the long table, clearly having to force himself to kiss Lora's hand, who was giggling and farting in delight. Not for the first time, Merlin had to question just what about this woman was so dangerous.

Uther proceeded to publically welcome the visiting king and his daughter to Camelot, then called for everyone to enjoy the feast. Merlin spent much of the next thirty minutes refilling goblets. He was next to Morgana for a moment and she sent him a glare filled with daggers. Merlin awkwardly looked away. He knew Uther's ward was evil, but he still felt guilty for trying to poison her the year before.

At last, the feast was finished. Morgana feigned a gleaming smile at Uther. "How does a bit of desert sound?" She asked.

Uther raised his goblet. "It sounds like a lovely way to finish the night."

At that moment, Gwen came out with a cake large enough for the party. Merlin had a forboding feeling about this cake, but there was nothing he can do to stop them from eating it. The only ones not enjoying the desert were Morgana and Lora.

Moments later, the Royals were dropping their heads in a deep sleep. The few servants in the back were looking at each other in horror.

Gwen raced to Arthur, shaking him. "Arthur!" She called.

Morgana stood up. "What's happened to them?"

Like you don't know, Merlin thought. Where was the Doctor?

"Hehe," Lora giggled, standing up as well. She reached behind her back and Merlin heard an odd zipping noise. To his horror, Lora's skin fell away to reveal a large bug- like green monster with beetle- black eyes and razor- sharp claws. The slitheen groaned joyfully. "It feels go good to be out of that skin!"

Several servants shouted out in horror and bolted out of the room. The slitheen laughed as it moved toward the sleeping king.

"Stop!" Merlin cried.

The slitheen glanced at him. "What do you think you're going to do?"

Merlin was at a loss. He couldn't use his magic with Gwen and Morgana watching, but he couldn't just let Uther die either. Maybe it was time to reveal his magic afterall, even if it meant the one enemy that was so close to the king would know and likely hold it over his head.

"Stop!" Came another voice from just outside. The Doctor, followed by Amy and Rory, came thundering into the hall.

"I take it the really ugly thing is a slitheen," Amy murmured.

"Love, it may not be best to insult the giant green alien," Rory shot back.

Lora- or at least the slitheen that had taken refuge inside her skin- looked around, as if unsure who to kill first. The Doctor took her hesitation as a chance to slowly move forward, his hand carefully sliding into his coat.

"You have a choice," he said calmly. "Leave this planet now or I will have no other option but to destroy you."

"You? Destroy me? Please!" The slitheen lunged for Uther. Quick as can be, the Doctor pulled a bottle out of his coat and threw it at the monster. It smashed, and the smell of vinegar hit Merlin's nostrils. Seconds later, the slitheen exploded, pieces of its gore falling upon more than one reason.

Merlin looked at the Doctor, bewildered. "How...?"

"It's their weakness," the Doctor said. "Camelot is safe, Merlin." He glanced at Morgana, who was surprisingly maintaining her composure. "For now."
