This is a prompt fulfillment for the combination of the tropes: "No, stop" (Day 4 Whumptober Prompt), "It's just a shadow", "You can scream all you want." (From my badthingshappen Bingo Card). Captain Pan / Rated T / ~275 words
"No, stop!" Hook cried out in pain, wrestling the umbral figure that had come out of nowhere. It felt as though the specter was ripping him asunder, rending the very fibers of his being causing them to fray in agony.
"What's the matter, Captain?" Pan taunted. "It's just a shadow, remember?"
The smoke like demon continued to peel Hook's shadow from his body, slicing through him with a vile magic as if he were skinning him alive. Piercing screams echoed off the cliffs. Lines of perspiration ran down his face, mixing with hot tears of anguish that could no more be held back than his cries.
"You can scream all you want," Pan said in a bored tone, circling the tree the Shadow had Hook pinned against. "It only obeys my commands." To prove his point he called out to the shadow and the tearing sensation at Hook's soul stopped.
Pan stood in front of Hook, his imaged obscured by the dark misty form. Hook lifted his head and shut his eyes, his breathing labored and weary from torment. Micro convulsions pulsed through his aching nerve endings, and he wondered how long the sudden reprieve would last. He balked at the feel of Pan's hand against his cheek. Snapping his open, he was alarmed to find the demon boy so close, holding him place with a different magic than the now absent shadow.
Pan leaned in to whisper something in Hook's, and the words sent a shudder down the pirate's spine.
"And unless you wish to keep your shadow attached to your body… you're going to obey my every command, too."
