She is a temporary Sergant and even that rank was only given to her to wriggle around some palace regulations. For all intents and purposes she is an independent advisor with little to no real authority. On top of that she's only been a sergant for what... tow day? And she was closely attached to Arcadios.

Due to the political infighting in the castle guard, her being new and her very low ranking position (and even that only temporary) I doubt she'd get any information at all, beyond what Arcadios told her himself.
