+ Someone from his illicit past who shows up disguised as personnel with some 'plans' to tempt and get him back in. Maybe even the girl who betrayed him and broke his heart by selling him out to the authorities when they were kids for extra dramz?
+ A rival, or someone he just does not get along with. Would be delightful if it ranged back to the Academy days. Bonus points if class and 'legacy' were a major factor in their mutual decision to hate each other with the fiery passion of an imploding sun.
+ Saw somewhere that someone was bringing a therapist in... someone please help this emotionally averse man-child have a serious conversation without getting him wasted first.
+ The unfortunate cadet who gets paired with him as an apprentice. Probably drew the short straw on that one. Questionable authority figure, ahoy!
