"Darling, BEHIND YOU!!"

Cynric screamed a second too late as the attacker, which had been thought to be dead a few moments ago, lashed his sword at the smaller skeleton. The blade cut across his neck, leaving a clean mark burrowing through the bone. Without much effort, Darling's head flew and toppled to the ground.

Cynric let out a strangled sob as he watched the one he loved collapse before his eyes. He tried to move, but the sword wedged in his shoulder was pinning him to the wall, making any small movement excruciating. Hot tears spilled down his face as he cried. "You- YOU BASTARD!!"

The attacker chuckled darkly as he twirled his blade a bit, admiring its handiwork. "Sorry, but I thought that little guard of yours was too annoying to keep around."

If Cynric had blood, it would be boiling to the point where volcanoes couldn't even compare to him. "YOU'LL PAY FOR THIS!"

The attacker gave him a sly smirk. "I doubt I will-" His expression suddenly strained as his body flinched. Cynric's passed expression turned to confusion as his attacker stumbled before falling in front of him. Bewildered, Cynric looked up at his savior only to stare in silent horror.

Darling's beheaded corpse stood silently before him, arm morphed into a horrid blade which dripped with the attacker's blood. It stood there, still as a statue, as if staring back at Cynric. The king was paler than bone white.

Then, it stalked over to its discarded head, bending down and picking it up. With a few adjustments and errors, the head reconnected to the body flawlessly. Once it was done, Darling turned back to Cynric, his yellow iris flickering back to life.

"My Lord, are you alright?!" Darling quickly blurted, realizing Cynric's situation a second later and running to his aid.

Cynric stared at him in astonishment. "H-How-?"

Darling tried removing the sword, only earning a pained hiss in response. He let go, worried. "I need to get something to stop any bleeding-"

"Darling." Cynric pushed. Darling paused. "How did you... he cut off your HEAD!!"

Darling blinked. "I know."

Cynric sputtered. "BUT YOU'RE ALIVE??"

Darling frowned. "Um... I am."

"How?!"

"I-" Darling looked to the side. "I'll tell you about it later."

((Skeleton logic my dudes XD

Now, Nome of mine do XD
YET
I might change my mind uwu))
