A/N: Goodness me, I forgot to mention the previous chapter was for JJuna on HoC who wanted Lancelot to overhear Arthur mistreating Merlin and come to his friend's defense, telling the prat about what Merlin has done for him :)
This one, however, is not from a prompt - though it was inspired by a tumblr post (message me if you'd like the link ^_~)
Just a hint of crack in this one :D
Guest: Thank you! I'm glad you're enjoying them so far :) Your requests have been added to the list!
"When will this end?" Arthur growled, the sound echoed by soft thunder above his head.

The cloud puffed up as a semblance of Merlin's face formed, cheeks round and crackling with lighting.
Arthur lost it, holding his stomach as he guffawed.

"Merlin!" He spluttered, already soaked completely through.
Another tongue of lightning streaked downward, scorching the ground an arm's length from the protesting man before the cloud darkened even further and floated off.
Gaius watched all this with the face of a weary parent, muttering to himself.
