Pearl's position within the Ten Stonehearts

As Himeko mentioned earlier, seems like Pearl has a very different personality compared to the Ten Stonehearts we've met so far. While she's still loyal to the IPC and the Preservation, she seems to be taking a more controlled approach to negotiation compared to the pushy Jade/Topaz or the uncontrollable Aventurine. Himeko and Welt even seem a lot more favorable when it comes to cooperating with her.
The situation of the IPC on Planarcadia is a bit different compared to other planets because seems like Preservation and Elation are, on the surface, at least acting on friendly terms. Both Sparkle and Sparxie doesn't seem to like them and treat them as invaders, but everyone else seems to be fine with them being around and providing technology and such.
Of course it's IPC we're talking about so it's almost certain that they're going to be somewhat antagonistic to the player as they'll always prioritize profit, but I'd like to see them at least once in a more positive light.

Also, as seen from the screenshot below, seems like Jade want to make the Ten Stonehearts collaborate and act as a group, but that just isn't going to happen easily considering how differently they try to achieve their goals. It also reinforces the fact that they're all "equal" and they don't really receive order from anyone except Diamond (who is the original Emanator of Preservation).
Also she looks like to not be fully human? Look at her hands and shoulder, those are clearly "puppet"-like isn't it? Intellitron maybe or some other race we haven't met yet?
