Pool of blood
Merlin brought the blood stained hunting knife Arthur had given him down on his pale scared arm. Enjoying the familiar sting of his thick blood flowing down his wrist, mingling with his glassy tears on the way down to the growing pool of crimson blood he was currently kneeling in.
Merlin smiled to himself sadly, his broken blue eyes filling with more tears. He was going to finally die tonight, he was going to be free tonight; Free from everything, all the pain and suffering and death.
Merlin could feel laughter bubbling up in his stomach, and let out a small giggle which soon turned into hysterical laughter. He threw back his head a manic grin splitting his tear stained face. He was going to die tonight, the thought shocked him, and even thought he had been building up to this for weeks, months even. His laughter abruptly stopped and his wide smile faded in to a confused frown, did he want to die? Yes, he told himself of course he did, you want to be free don't you?
More of Merlin's crystal like tears joined the pooling blood as he tried to convince himself his death was for the best, for him and for everyone else. Merlin's raven black hair was matted with blood and his skin was paler than normal, even if he changed his mind now it would be too late, he started laughing again his manic smile returning, but his time it was mixed with more tears and his breath coming in short gasps. Merlin toppled backwards into his pool of blood and tears, it covered him making his dark hair seem blood red, with his last breath Merlin grinned and whispered "Screw you destiny, I'm in control now."
