As usual, the villainess is making a stupid move again. Girl, if youre gonna kill her, just kill her so theres no chance of her getting away or whatnot. Or if you're dead set on torturing her, at least disfigure her badly so that she cannot be recognized. cut off her hand and tongue as well so she can't communicate. Hell, maybe you can even cut her feet off while you're at it. Just keep her barely alive as you torture her slowly.
P.S. I don't hate Ripley or anything. I'm just tired of stupid villains.
