Snape approached Hermione menacingly after accepting some items from Arthur Weasley. The spreader bar between her feet meant she had nowhere to go, but with an expansive wand wave the former Potion Master conjured several lengths of chains which he connected to the former witch’s collar locking her in place. With an evil grin Snape proceeded to add some discrete elements to the captive’s imprisonment, he placed opaque contacts into his victim’s eyes. He nearly creamed his pants watching how her eyes darted in fear around the room, now only making out the faint grey shadows of people where once there was a world full of the nuances of light and colour. He liked to see the terror in his victim’s faces, masks and blindfolds never pleased him aesthetically. Next he fitted the captive’s ears with a pair of earplugs, he toyed with forcing the trembling witch to enjoy a recitation of all the slutty things he had forced her say in Arthur’s lab before she was reunited with her parents but for the moment he thought white noise would be the cruellest option, leave her second guessing at what was happening. He knew from reviewing the control port telemetry that his little mudblood bitch responded especially badly to sensory deprivation. Snape grinned malevolently, these security measures made sense and he’d lobby hard to make them permanent when her surgery was scheduled.
