Syca's Record #15: Deviating Expectations

I told Vaha of Orze's betrayal, but I never expected his response: "Would it not be best to take this up with the master? What can I do about it?" How could he defend a traitor such as Orze? I don't understand. How could I have miscalculated? Wasn't Vaha a man of principle? How can his reaction be so dismissive when he is the one who most closely obeys Dehkia's every order?
