So unless a person has been reading a ton of Star Wars novels, it's actually easy to skip over most of Thrawn save for the occasional mention of him... so I suppose there's some wiggle room here.

Fourth wall breaking for general Star Wars stuff would be fine, and he might use her enthusiasm to get her to do things 'How would you like to learn how to maintain a hyperdrive or fix a blaster turret' to get her to crawl into unpleasant but necessary maintenance places.
