I'm convinced one of the reasons the first two episodes of Discovery seem so...incoherent...is there were extensive rewrites after much of the footage was already filmed. For example, the writing made Burnham's "mutiny" out as being much worse than what was shown onscreen. Maybe she originally successfully fired on the Klingon ship, but they edited it out because they thought it reflected too badly on her character? All of the Sarek scenes were unnecessary for the narrative and seemed to have been ported in at a later time - maybe after they decided Michael was Spock's sister. "Part 2" being so short seemed odd as well...as if they left a lot of footage on the cutting room floor, or else added a bunch of stuff in post-production and realized it was too long for a single episode.
