There’s no doubt that it will be reveal, but I rather it sooner than later. Meanwhile, there is something that can be a clue:
That’s Zero Two’s hand alright. But is the other hand Hiro’s? I hope so. Maybe they met when they were young, but he just forgot somehow. Maybe it’s some other child. This might be a little hint for her past.
Maybe the reason why she wants to find a man is as simple as it sounds, so that she won’t be lonely. Zero Two has a lack of empathy, but it doesn’t mean she doesn’t feel any emotion. Sometimes she does and just chooses not to express it. With that in mind, Zero Two’s search for a man who would stay beside her and support her becomes…self-explanatory. Everyone needs to have somewhere, someone to lean on, even icy dinosaur girls.
