The Dimensional hopping Imp took a fancy to the Blonde he saw. So he came back and decided to swap out her mind with his own pet Parasite. So the Blonde would then like him come with him and do what he says. While her mind would be suck in the Jar the Parasite lived in. That way he would now have two pets to take back to his Dimension. One that walks around and is Blonde and Beautiful and another one that lives in a Jar.
Well, I guess with the mind of a parasite, that blond is feeling a strong attachment to him. Damn, I think this may be your most twisted switcheroo yet!
