Well, maybe she’d be impressed a bit, especially since he’s able to master a power most humans don’t have, especially since he doesn’t have a gem, but since he’s done such terrible things with it, she’d probably still be disgusted with him. (Though, because Pink might’ve seen something of The Je’daii long ago when the diamonds invaded that galaxy, then were driven out, wouldn’t she know what to expect? Or at least know they exist and use some kind of dark power to defeat the gems? I almost wonder if she, and maybe the other diamonds thought this too when they were there, they’d think that ordinary organics that don’t posses gems but are force sensitive are all users of this dark power, and thus they’re all to be feared and avoided. Seems like something homeworld might do, and on top of that might think that organics shouldn’t be trusted with such power and therefore shouldn’t exist. Though, maybe Luke might change their minds. Sure, Steven existed before that, but since he was part Gem, maybe they didn’t really think he fell into that way of being.)
