Snape consented to the prisoner to be drugged, once she was securely fastened to the surgical table, he was amused rather than annoyed at the now-bound witches fruitless struggles. Once he had knocked out the patient, he removed the contact lens and earplugs safe in the knowledge that Arthur Weasley would be installing more convenient upgrades. While they waited for the Engineer to bring the tools of his trade. Snape directed Madam Pomfrey to look after some lowkey adjustments (beyond the obvious new flaring of her hips and elongated her limbs that Umbridge had completed). The shortening of the tendons in their captive’s legs (making it impossible for her to walk without comically high heels, thus lessening the already non-existent risk of escape) was completed without a fuss. In a deft piece of work the matron augmented the thumb muscles on the slave’s outstretched arms, ruining any conscious fine hand dexterity from the witch. Her hands could be spelled into the rudimental shape for impromptu hand jobs if any of her master’s required it, but the bound witch would no longer be able to pick up and use tools anymore.
