"Are we talking via telepathy?!"
Alissa became a bit excited after the small discovery of hers, and because of her excitement, she had almost forgotten how dangerous and evil the supernatural woman really is. Her excitement is reasonable however, because it was the first time for her to hear someone talking to her in the same way her lover did. The way of talking that is basically similar to telepathy, which is talking without a real source of voice, but with a mental connection that tries to communicate with another instead.
This form of telepathy is kind of particular. It's the normal way for ghosts to speak because they're basically just remnants of consciousness, but a telepathic way for humans and whatever intelligent creature to speak.
