A/N Wow. I can't believe it! Reviews, favourites, follows, all doubled overnight! THANK YOU TO EVERYONE WHO'S HELPED THAT HAPPEN :D

To everyone who's suggested prompts - thanks :) I can safely say that all of them have bred plot bunnies, even if they've mutated a bit...

"Well that wasn't meant to happen."

"Merlin, how many times do I have to tell you not to experiment with your magic?"

"I didn't mean it to explode like that, Gaius! I just wanted to make it smell a bit better."

"Merlin, you shouldn't have tried to do anything to it! How are you going to explain this to Arthur? You've just blown up his stables! It's a small miracle the horses are still alive!"

"Um, I'll think of something?"

"What's going on? Merlin, what have you done to the Royal stables?!"

"Uh, I..."

"Well?"

"...was trying out my new interior decorating skills. I thought the horses might enjoy it if I spiced up their room, you know?"

Arthur glared at Merlin.

"Okay, never mind, um, it was a gas leak? Wait, that hasn't been invented yet. So maybe it was the horse's fault. There was a suicide bomber. The building was so excited it felt the need to explode. It really needed to pee, and it couldn't hold it in any longer."

Arthur remained surprisingly unconvinced.

"Right, okay, ignore that, uh..."

Merlin caught sight of a figure across the courtyard.

"It was Gwaine," he pointed in the right direction. "He did it."

Arthur stormed towards Gwaine. Merlin winced in sympathy for the knight momentarily, before turning and fleeing.
