Author's Note: I can't believe I made it to twenty! A huge thank you to everyone alerting, marking as a favorite, and/or reviewing this story! You guys are awesome! In honor of the twentieth drabble, I am making this the first of a series of drabbles centered around Merlin and Arthur, and the series will contain some brotherly hurt/comfort. Enjoy!

Disclaimer: I obviously do not own Merlin, regardless of how much I would like to.

Chapter 20: Exhaustion (part 1 of 8)

Something was wrong with Arthur.

Thankfully it wasn't life threatening. Merlin had saved the prat from enough things to know when something was or was not potentially fatal.

Still, the prince was definitely not himself. He seemed exhausted, and it had been getting worse.

Arthur was well-trained however, and it didn't seem to be throwing him off. Merlin was probably one of the few who noticed, and only because he knew his master so well.

Merlin was getting worried. Something was keeping Arthur awake, and Merlin suspected nightmares. Whether it was or not, Merlin wanted to find out and help.
