oh the dynamic with whatever Wes thinks abt Nabi (from what you said so far he doesnt trust her and thinks she'll do whatever the fleet says) now that she explicitly said she doesn't want to hurt him, and even when she did read his mind, iirc Mel that had both Nabi and Mercury do it said it feels different if the person is not trying to make it hurt, so if Mercury has, not accidentally, done some psychic torture on Wes, he'd notice it feels different when Nabi does it and then wht will he think/feel about it
Wes has never personally had The Mercury Experience™, but if he did, he'd be aware that it's a lot worse than what Nabi's done.
Her powers are invasive, and can cause both emotional and physical distress because the person who the memories belong to are reliving them, but she's not as forceful as Mercury
It's the equivalent of being grabbed by the hand and pulled along at a sprint vs being grabbed by the ankle and dragged behind the other person while they sprint
