Actually, you did. See below. In retrospect, that may not have been what you meant, but it certainly was what you said (wrote):
BTW, I think the scenes on the planet with Georgiou and Burnham along with Burnham's flashbacks on Vulcan, her interaction with Sarek's katra on the ship, her conduct before, during, and after, the battle, and Georgiou's conduct before, during, and after the battle, helped "establish" those two characters pretty well. We also got a pretty good idea of who Saru was as well, prior to, during, and after, the battle, IMO. I know you may disagree.
