About NiCO: I don't think NiCO is her actual name. The capitalization on the letters is odd and she's a scientist. Based on these facts my theory is that NiCO is a codename/nickname (just like Rig's real name isn't Rig). I believe her name is an acronym of chemical elements, so Ni = Nickel, C = Carbon and O = Oxygen. Together that would make the name 'NiCO' with that particular capitalization.
