Romana/Demon!Leela/K-9
Her mind worked quickly on a stratagy. Yes, yes that would do it. "Please do assist K-9. Stun only, there are humans in there" she said glaring at the black eyed monsters taking the complex people like this. They had no right. Of course they had no right. Not that demons cared about such things. But they were not without hope. Not everyone was taken. When the demon that dared to possess Leela spoke Romana levelled one of her glares at it. A glare that had even made the Dalek Emperor think twice about killing her. Very much the War Queen when she needed to be. She supposed she had the Master to thank for that. He gave her a strange sort of confidence.
"And Greetings to you I suppose. What am I to call you, as I won't call you Leela. Every second you inhabit her is an insult and I won't have it. She deserves better than this and I am going to see that she gets free of you"
Romana most definitely was nervous. It was her friend in there and she had a gun and little else. Still Time Lords were never without failsafes, if nothing else she had a sonic screwdriver. If nothing else she could hit her on the head. She had ways and means. "You are going to leave her. You and all your friends are going to leave. Leela knows what I can do. She knows only too well"
It was possible to scare the demon with what Leela knew. It was an idea. "You do know I have claimed this place as my own don't you." she let her gaze darken and her lips curl into a sneer. "You have your puppet and I have mine, and if you kill this body then I'm going to get very annoyed at you, years and years of work, I created her, I engineered her before her birth and she is my ONLY chance to restore my people"
She hated doing this, hated even remembering the part of her that had been Pandora. Dead and gone yes but she knew Leela would fear her, and with good reason. Maybe the demon, using what she knew of Leela's memories would too. Romana would.
