Ok, this is this kind of story. So here is my guess for next chapter: What Pelletro did will remain hidden. Not matter what happens, she won't tell what he did. Again. UNLESS Baraha says it first at some point (granted he can). Even if Pelletro were to die, he will die a 'good' death, with nobody ever aware of what type of guy he was. For posterity, he will be the victim that died in tragic circumstances. She will cover for him. For no reason. Because this is a trope.
