A/N: Sadly, I do not own Sweeney Todd and Hellraiser.
Mrs. Lovett's screams slowly faded into silence as Sweeney Todd leaned on the bake oven door, eyes settling on the lifeless body of his wife, Lucy. Razor clattering forgotten to the stone floor, the barber walked toward her, body and mind detached from one another. Kneeling at her side, he began to cradle her in his arms when he noticed something on the ground next to the prone form of Judge Turpin. Standing swiftly, Sweeney crept over to his deceased nemesis and picked the object up, unconsciously aware of a sewer grate scraping behind him.
"This is for me mum, you monster!" Tobias screamed, launching onto the barber, wildly swinging the sharp razor. Uttering a startled yelp as Sweeney slammed him to the hard floor, he froze when cold metal touched his exposed throat. Fighting to breathe against the weight pinning him down, the boy whimpered, fearing he was about to suffer the same fate as Mrs. Lovett. However, the barber paused in the act of raising the blade, gaze going to the mysterious box that had fallen to the ground.
"What are you doing?" Tobias squeaked, watching Sweeney lift the box, fingers probing its surface. Ignoring his question, the barber cautiously traced a large circle on the cube's front, letting go as blue energy engulfed it while part of it rose, clicking forward before ratcheting back and lowering silently. Pitch blackness blanketed the bake house, snuffing out even the light from the oven. Heart pounding, the boy felt Sweeney get off him, allowing him to draw air into his lungs. Mustering the strength to stand, Tobias yelled, legs crumpling beneath him, pain radiating where the barber had slashed savagely with his razor. "Bastard!"
"Insolent pup!" Sweeney snarled, faltering when white light pierced the darkness, blinding them both. A violent quake struck the room, tossing them to the floor. Grabbing onto the meat grinder's handle, the barber struggled to his feet, jumping as a section of wall cracked apart to reveal a vast network of corridors. "This is Mrs. Lovett's fault, that witch! Now she's tricking me with these illusions!" Growling, Sweeney rounded on Tobias, who shrank away, injured leg leaving a streak of blood. "Your death will put an end to this madness once and for all, boy!" He started to advance, but was stopped by a slick chain that speared through his hand, tearing the razor from his grip. Bellowing, the insane barber dropped to his knees, hot blood pooling around him.
"Now, can the two of you behave sensibly, or do I have to inflict more pain?" Several monsterous abominations stepped out of the gap in the wall, clad in leather. One had pins driven in his head and face, expressionless ebony gaze raking the two groveling people. "You, barber, opened the Lament Configuration, releasing Hell. However, you did so out of revenge, not desire. Therefore, we shall take the child in exchange for you. Interfere and the cost will be your soul."
"Mr. Todd!" Tobias screamed, hearing the rattle of many chains in the darkness. Powerful hands hauled him back so that he narrowly missed the links that arrowed at him. Cheat heaving, the boy looked up--and choked, tears prickling his eyes, the face of Pinhead looming above him. Off to his right, Sweeney sat hunched, dozens of chains having impacted his frame, rivers of crimson fluid around him. Glistening eyes met Tobias's, then went blank as the steel links abruptly pulled, ripping the barber apart. "N-no!! Please!"
"Too late, Toby," Pinhead drawled, using the nickname Mrs. Lovett had. "We Cenobites always get what we came for." Digging his fingers into the child's flesh, the demon carried him to the hole. A loud bang signaled that the wall had sealed and Tobias was forever locked in the hell that he always imagined: Sweeney, the barber shop, blood, screams, and the razors.
Echoing yells rang throughout the Labyrinth as Tobias's eternal torture began.
