Rhode temporarily put aside the matter regarding Ion and giving Erin an official job title was simply his first chess move against Ion. Since Ion decided to plant Erin over at Rhode's side to hold him back, Rhode couldn't be blamed for using Erin to intervene with the political affairs of the Country of Darkness. Rhode was incredibly clear of Ion's intentions, which was why he made this move. He also decided that if Ion continued playing his game, he would proceed to send Angelina over during this period of time, support her in defeating the Vampire Countess, Ashvril, of the four legendary generals, and get Angelina to take over the vampire forces.
Since you want to find trouble with me, don't blame me for returning the favor, Your Majesty Ion.
