After fighting guards and abominations , the strange duo decides fighting the prison guards will not work and come up with a plan : Andarin will distract the guards and Trevor will free the prisoners . Knowing he has no other choice , the paladin agrees . Trevor quickly manages to get ahold of a keyring and opens the door of a cell in which a girl was locked up . The girl recognizes the Forsaken and is shocked at his appearance , but Trevor simply bows , saying " " Good evening , my princess . " " Given the statement and his standing before becoming one of the Forsaken , it is possible he is showing deference to Princess Calia . Feelings for Prestor .
