Honestly, it's not surprising at all that she's most likely done. There's been signs of that for almost a year now. I'm pretty positive Lily and VS parted on good terms, because she and Caleb sent Ed flowers back in August that he posted on his instagram and mentioned something about enjoying their vacation to the Bahamas. So I think if she wanted to come back for one last show next year, it would be possible. I hope she does but at the same time, she might want to go out on a high note (as an angel, closing a segment, etc.). She has a lot of stuff going for her right now so I'm not worried about her career, it's just a new phase of it.
