AN: Thanks for the reviews and story alerts. Like I said before; any suggestions that you have, no matter how childish will be welcomed.

War was officially declared the next morning. Merlin and Gwen, in an attempt to try and prevent the inevitable trouble/chaos/disaster had tried their best to try and talk Morgana and Arthur out of the war. However neither prince nor ward was willing to listen. The declaration of war came with the first attack.

Morgana woke up early the next morning feeling on edge. She'd had another one of her dreams. She couldn't explain it or remember it that well but there was a woman in it. A woman with blonde hair whom Morgana had felt a connection with; someone she could trust. Morgana shook her head; it was still quite early. Morgana lay back onto her pillows and tried to forget her dream. She needed something to focus on.

Then she remembered. She was at war with Arthur and it was vital that she struck first. Not just because it would allow her to have the upper hand but 'Ladies First' was proper etiquette after all. The prank had to be something clever, something devious. Morgana looked around for inspiration as Gwen arrived with her breakfast. As Morgana ate; she hit upon an epiphany. Arthur would be expecting her to pull something big as a first attack therefore he would not be expecting something childish like…

"Gwen I have a plan."

"I take it you're still going through with this immature war?" Merlin asked as he delivered Arthur his breakfast.

"I told you before; it isn't childish. It's about superiority." Arthur replied. Merlin rolled his eyes as he set out Arthur's clothes. "And don't forget my stables need mucked out."

"Yes Sire." Merlin muttered sarcastically as he fetched Arthur's chainmail. Once the prince had dressed, he went to train with his knights. Arthur walked through the corridors, trying to figure out how to prank Morgana. He needed to be clever, sly and the prank had to be something humiliating to remind Morgana that he was a prince and therefore superior to her. Arthur was lost in his thoughts and didn't see Gwen until they collided and fell to the floor.

"I'm so sorry Sire; I didn't see you." Gwen apologised as she helped Arthur get to his feet.

"It's fine Guinevere," Arthur replied. "Should I be worried about Morgana?"

"I'm staying out of this Sire. It's between you and Morgana." Gwen said. Arthur studied her for a moment but walked away. Gwen smiled to herself as she hurried back to Morgana's chambers.

"Well?" Morgana asked.

"I did it. We just have to wait." Gwen answered.

Three hours later Arthur returned from training in a foul mood. There was something wrong with his men. They had been sniggering like a bunch of schoolboys throughout training but none had refused to tell the prince just what was so amusing. The strange state of hysteria had continued as he walked around the castle with guards barely concealing their laughter with coughs and maids giggling like young girls. When Arthur reached his chambers he studied his reflection. There was nothing on his face or clothes that would prompt such strange laughter. For the life of him, he couldn't figure out what was wrong with everyone. Maybe they were all under a sorcerer's spell.

"Now I'm sounding like Father, that's all I need." Arthur muttered as a foul smell reached his nose as Merlin entered the room having mucked out the stables.

"Anything else that," Merlin trailed off as he tried to hold back his own laughter and snorting. Arthur spun around and glared at Merlin who hurriedly tried to compose himself.

"What is it that everyone seems to find so funny?" Arthur demanded. Merlin walked over and pulled something off Arthur's mail and handed it to him. It was a piece of parchment with an arrow pointing upwards and Morgana's handwriting on it.

"Camelot's biggest idiot."

Arthur crumbled the parchment into his hand. He hadn't seen Morgana all day so how did she manage to- no, it wasn't Morgana. She had masterminded the childish prank it but Guinevere had been the one he'd walked into and who had 'helped' him up. She must have attached it then. Arthur stormed out of his room and headed for Morgana's chambers. As he neared it, he could hear Gwen hissing a 'He's coming!' to Morgana as he pushed open the door.

"Arthur, what a pleasant surprise." Morgana said politely. Gwen was keeping her gaze on the floor she was sweeping but there was a grin forcing its way onto her face.

"Really Morgana? A sign on my back? Is that the best you can do?" Arthur demanded.

"Of course not Arthur. You're Camelot's biggest idiot, not me. I'm just getting started." Morgana warned.

"Well just be careful. The second you let your guard down is the second I strike." Arthur warned and walked out of the room. Arthur was trying to plot his revenge. Morgana had taken the first, albeit childish, attack of the war. He needed to retaliate and quickly. Since Morgana had decided their pranks were to be something childish. Arthur was going to strike back with something even more childish.

It was time for him to get his hands dirty.

AN: Yes I know I did a variant of the 'kick me' sign, how crap. I doubt many would have dared give Arthur a kick up the backside, well Merlin would relish the chance but that's because he's Merlin.
