>>119321983>Maybe Neo will be just there to help or protect Emerald, in case Cinder escapes and flies off by herself.
I didn't understand if Neo is going with Emerald and Cinder to Amity or not, but it does seem the writers want to make this time hacked Penny be the one that attacks them, as if it were divine retribution for getting her "killed" against Pyrrha during V3.
Neo staying in the whale could get her some unexpected interactions with Salem, Hazel, Tyrian, Mercury, and even Oscar, but going with the other two girls could prove useful for Emerald's protection, since Penny counters her Semblance hard. I don't think Emerald can be useful at all against Penny, since she's a machine. Neo's illusions at least have physical properties and her clones are made of aura, and she probably wouldn't leave behind Emerald to die, unlike Cinder.
