After his discovery, Ves acted out a play. He pretended as if he was as frustrated as the other Vandals, not even hesitating to demand a meeting with Major Verle to obtain some answers.
The rigid mech officer refused to spill the beans, just as Ves expected. The man had a point that a secret as momentous as this should only be known by those who needed to know. Ves did not actually require an answer to perform his duties, so he was firmly on the very large list that definitely didn't need to learn the truth.
Ves couldn't blame them from withholding the fact that they imprisoned Lord Javier and was attempting to bring him out of the Kingdom. Though their greater motivations escaped him, the Vandals would surely be doing it for a reason.
