I've no idea how running these tests or giving examinations works in the first place, but if you spot some similar symptoms among Miss Akaba and the warden but not Mister Mykk, it most likely isn't due to the Prince's actions. They both were subdued in, erm, a unique way which could explain the symptoms.

[ might want to tell the medical team "who has two thumbs and knocked out people via creepy drug smoke, this guy." ]
