Initially, Graves appeared to be a person of great control. While waiting for the interrogator, she sat completely still for about three hours barely blinking. However, while interrogating Graves, Commander Lowell described her has having a cold blue eyed stare.

She showed no remorse, was calm and methodical showing no emotional response.
Walker is considered to be one of the best cruiser-class pilots in the Planetary Union Navy. After his final piloting trials, he was accused of rigging the system because he scored off the charts in all reaction-time and subconscious physics processing tests. Walker is the only candidate to have passed the test, yet been forced to take it a second time. At the second trial he scored even higher than the first. The tests scores were re-calibrated afterward and Walker's scores set the benchmark for a perfect score.
Walker was tried in a secret military tribunal for the murder of two children, and the rape and murder of a civilian. Walker was convicted and given an opportunity to have his record expunged if he served two years aboard the Keeling.
