The whole scene makes very little sense. It would be much more logical for Reva to present herself as a friendly face, and a representative of the Empire put in charge of bringing Leia to the safety of her parents, in hopes of getting at least some information. All Leia knows is, that she was taken by some pirates, and then apparently rescued by a former Jedi, who themselves are wanted criminals. There’s no subtlety in Reva’s character. She’s just a one note villain, who’s inept at interrogating a little kid, fails to recognize her innate Force ability (which is her job), and wants to torture her for information, she likely doesn’t have. Presenting a friendly face would make the Reva character more interesting, and competent, being able to do more than just yell and scowl.
Glad to see this, that moment also stuck out to me as really Disney-fied like they’re playing to the kids out there who see themselves in little Leia. That’s fun in an interactive theme park setting and ultimately Star Wars is for the kids more than the adults, but for a serious scene the more intense the interrogation got the sillier it was. If Reva handled the situation like you suggested (which is how real interrogations typically go) the whole scene would improve, Reva would have more dimension as a calculated villain instead of her usual one note, and Leia by rejecting her manipulation would reinforce her inner wisdom and even call back her skepticism of Kenobi in episode 2. I get it, the inquisitors are ruthless and it’s sort of been established that force mind reading is Reva’s thing, but in the wrong scene with the wrong character it can (and in my opinion did) go over the top and feel even cheesier than all the last minute saves.
Reva better break out that backstory soon and it better be worth it, right now the more she tries to act scary the less intimidating she gets, the character is becoming a cartoon.
