Is Evelynn's Stealth Going to be Explained in her VGU?

I love Eve. I love stealthy champs. The thing I don't get with Eve is how her ability to merge with the shadows ties to what she is, and to a lesser extent who she is. She's some mysterious, sadistic, demon / succubus kinda lady, summoning spikes and just kinda scratching at em works with that. Why can she go invisible though? Like how does that tie to her nature as a weird kinda sadistic succubi? She doesn't seem like the kind of person who would be concerned with being unseen, or have those abilities. In the road map it talked about her having a shadow form and the animation for her Q looked to me like the spikes were coming from her shadow. So I'm assuming she's also going to have some shadowy abilities? Stealth is such an iconic part of Evelynn's gameplay identity, yet for some reason it seems to me out of place with her character's identity. Anyone willing to tell me if her affinity with the shadows will fit with her overall identity in her VGU?
