The white chick with the white hair gives off very much the pink headed bitch in Last Jedi vibes.

That's Halsey, so that comparison isn't completely off base for the character (except Halsey is actually competent, and doesn't appear to care about much of anything except the survival of the human race (and herself) at any cost. I guess she also has that weird mother-child relationship with the Spartan-IIs, but even then she's not above sacrificing them to further her goals.
