Door Slice Part 2: Electric Boogaloo

He is scraping flesh from his scarificator (a brass disk that inflicts multiple lacerations via spring-loaded razor-blades, gathering the resulting blood into an internal cup) when he hears the thumping sound. A moment later, and the door to his cell is split in twain. The scarificator falls from his hands.

It strikes his lap. Blood splashes out of its internal cup and splatters over his mask.

SCP-049 lifts his head and meets the intruder's gaze. Blood drips from the needle-like tip of his "nose".

Don Quixote stands at the doorway, sword in hand: "My God. She was right — you're the biggest mosquito I've ever seen!"
