I agree with your observations about bloodlust vs sexual lust. It's clear she's a predator; a monster. I'm glad Gonzo chose to portray her this way, rather than the babe stereotype of the comics.
Okay, there's plenty of sexual imagery going on here. The 'fluid' is open to interpretation of-course; Gonzo would probably have you believe it's lubricant or oil. We are not fooled.
I wish someone would sub this.
