Nero noticed the visible disappointment on the doctor's face and could only smirk. Her obsession with studying his body was unusual to say the least, but she was reliable at least, and had kept his secret. Even though he had told her that the colour change was due to what he encountered in Perilith, it was a relatively weak defense.
Sure, it was more believable than having two innate abilities, so if it was ever leaked, Nero expected that the story would stand. But the problem was that upon intense scrutiny his story would crumble because he didn't have actual knowledge about what could change his eye and hair colour. Yes, he could continue to make things up, but such things could only work for so long. So, her discretion was greatly appreciated by Nero.
