The handmaiden comes off as (and genuinely is) less polished than the Senator, speaks slightly less carefully, gives away slightly more in the Force, observes the Jedi slightly less keenly. (They're not even on camera - the Senator's office doesn't tolerate potential leaks - but her Mistress can watch through her eyes very subtly.)
There's more hints at potential entanglement with the Intergalactic Banking Clan and Damask Holdings, and yet more at ties to the Trade Federation, or else to parties the Jedi can't see yet - entanglement they're trying to hide, right now, and that shows up unusually infrequently even in every other record Elesse can access. (There's patterns outside this office, in who's reticent about questions, who openly or subtly aligns themselves with the Naboo delegation. In where else money trails vanish or lead to suspiciously innocuous places. In what requests get tied up in red tape and what don't - red tape is just about a reflex here, and it's odd, too, how forthcoming and prompt the Naboo delegation is acting.)
Ravrí also very clearly likes Elesse. It shines even in her muted Force presence and the careful lines of her posture. She's possibly willing to be a bit reckless, just to get a chance to verbally spar with the younger girl. (Ravrí is also obviously not just new but young - possibly a graduate of the Youth Legislature program, possibly not, given that no one has ever figured out who Palpatine's handmaidens were before joining her service and all their accents are blandly typical of those from Naboo's royal houses. Either way, she's likely at most a few years older than Elesse.)
