The first woman left to find herself in season four, but we haven't seen hide or hair of her since! Maze still seems to be caught up in Eve's memory (though, they only knew each other for like a week), so there's bound to be something left there to explore. Even if nothing happens between them, Eve has sorely been missed! She was a fun addition to the story in season four and could do well with more fleshing out. The real question is if Eve does return, what will she bring back with her, chaos or peace?
