Play the damsel in distress

The newly formed dark lady thought quickly formulating several plans depending on who was coming.

First, she called out to Nyssa the Basilisk in parsel-tongue. The snake approached, and recognized its master, but asked "Master, why do you smell like a female now?"

"Because there was an unexpected complication with my soul-magic tap. I suppose that makes me your mistress now." The dark lady mused.

"Yes mistress."

"Regardless, we are going to have visitors shortly. I am going to have you hide in your lair, and then possibly call you out. If Harry Potter is among the rescuers, when you come out, I need you to ask what has happened as you no longer sense the will of your master. Do you understand?"

"Yes Mistress."

"Excellent, then return to your lair. And remember not to petrify or kill any of the rescuers. If they fire a spell at you, just return to your lair and await my further command."

"Yes Mistress." Hissed the basilisk as she returned to her lair.

"Hmmm, I do enjoy the sound of that. 'Mistress'... maybe Missy? Misty? Tess?... Misty. Yes disarming yet hidden in plain sight. Almost the opposite effect of my old anagram"

The newly named Dark Lady Misty turned her attentions upon Ginny's prone form, molesting Ginny with her eyes as she enjoyed the corruption she had put the previously innocent girl through. The Dark Lady Misty bent down to whisper into Ginny's ear.

"Now as for you my dear toy, you shall be rewarded for saving your mistress." Misty stuck out her long pink tongue and licked Ginny's ear. "But first, we must prepare our show for our rescuers. Obliviate!"
