A/N: SPOV
Severus was immediately disarmed and restrained as he was forced to kneel in front of The Dark Lord. I'm in trouble, it seems. His mind had already turned into the blank screen that he depended on for his survival.
"Ssseveruss... always the helpful one..." The Dark Lord's tone was unmistakably sarcastic, as the other Death Eaters laughed and taunted him.
"The Half-Blood, the Prince boy, thinks he'll ever get ahead by interfering with Lord Voldemort's plans." His blood ran cold.
"My Lord, I can assure you that I have always seen to it that your plans..." I objected, trying to keep panic and pleading out of my voice. The stern boot of Bellatrix went across his face and was only remaining in a kneeling position due to the magical restraints keeping him up.
"Hello to you too, Bella. Your normal spite seems to be missing from your tender ministrations. Catch your husband fellating muggle orphans again?" He asked, and got her wand casting the Cruciatus Curse directly into his chest for his trouble. Bellatrix seemed ready to verbally retort, but was cut short by The Dark Lord.
"Don't hurt him too much, now, Bella. You were the binder for that Unbreakable Vow." Bugger, he knows. I should have sworn them to secrecy.
"But I came and told you as soon as it had happened, my Lord!" She pleaded, but was put under the Cruciatus Curse anyways for her troubles. Her writing in pain always seemed to be borderline erotic, and Severus wasn't sure he would ever want to delve into her psyche.
"Draco was the only one to know about this mission, and instead his mommy came to you to plead for your help! Draco, you may stop tending to your mother and get over here." The Dark Lord's face was contorted in obvious rage.
Draco shuffled over quickly, and Severus was able to see that Narcissa had been subjected to torture by Draco's unwilling hand. Gone was the look of regal stoicism; nothing makes a woman look more beaten than crying as your own son is forced to use Crucio on you.
The Dark Lord pulled out a deep green Granny Smith Apple. This cannot be good, not when they resort to fruit. Severus thought vainly, and his mind went off to debate if an apple was a fruit or vegetable in order to withstand whatever was going to happen to him.
"The incantation is Sectumsempra, Draco. When done right, you'll only get the layer of skin off." The Dark Lord was peeling the skin off of the apple in a spiral manner, and Severus already knew that Draco's focus would not be good enough to do this without excessive harm. And on top of it, he's using my own spell against me.
"Severus, know that this is only a warning. You were right in your assumption that if Draco here fails to kill Albus Dumbledore, that the task does fall to you. I'd like to see the look of surprise on his face as you do it. But IT IS NOT YOUR PLACE TO QUESTION NOR ASSUME MY COMMANDS! Draco, skin his right forearm." The red-slitted eyes were sparkling with a cruel sadistic streak, only matched by Bellatrix's.
Draco looked like he was about to vomit, but he somehow kept his posture enough to begin the curse that would cut and peel the flesh off of his arm. Severus was glad that he had taken the potion in advance, if he withstood the pain and didn't pass out, there was a chance he could repair the damage quickly enough with the counter-curse and a lot of dittany.
The cutting was slow initially, but Draco got the incisions right at the wrist and spiraled with his wand as he used his left hand to peel the skin back. The look of horror was obvious on his face, and Severus pitied the boy while wishing to kill him at the same time.
He wasn't sure he could handle the pain and the intensity of what was going on, but he was eventually saved when Draco was told to stop at the elbow. The pool of blood at his knees was making him sick, while Bella crawled up to him and started to reach for the strips of skin hanging off of his elbow now.
"Not this time, Bella. If Severus displeases me again, you may eat whatever scraps you find." The Dark Lord chided, as if speaking to a reckless puppy.
"Half-Blood, you serve me at my pleasure. Do not become too acclimated to a position above your station if you continue to meddle in my affairs. Understood?" His voice was harsh and inhuman.
"I understand, My Lord." Severus said graciously, unable to bow or grovel due to the restraints.
"You may go, Severus. Draco, do the same to your mother now." As Severus staggered out of the room in order to apparate away, the last thing he heard was the screams of Narcissa Malfoy.
Severus landed at the gates of Hogwarts, having to use his left hand to cast rather than his right. He had sealed the deeper gouges from the Sectumsempra curse already, but the flaps of skin were already too far gone. He shot off his Patronus towards the castle, hoping in vain anyone could make sense of the blurry doe running off... to Hogsmeade.
I'm going to die right here, all because I didn't think to bring a blood-replenishing potion with me.
The after affects of Bella's Crucio was starting to hit him, and his body convulsed as his chest and back felt the aftershocks as burning, cutting sensations through his flesh and bone.
