eevee claims investigative and he didnt say that sarun results were wrong about him being nobility
that leaves cavalier fernand sky knight
he is not fernand since he would know if sarun is deliverance and that thing he did would be pointless
he is not cavalier since it doesn get N1 results
conclusion
he is sky knight who checked sarun and got nobility and then did that gambit since some deliverance starting roles are noblity
