Relationship between Percy and Vax'ildan

Percy and Vax'ildan were once very trusting of each other, but ever since Vex'ahlia's death due to Percy's own negligence, as well as other events, the two have not been able to see eye-to-eye. Eventually, they had a discussion and Percy told Vax that he wants to be in the rogue's good graces again, but for the time being requests that he "never trust him".
