Star Trek: Breaking Down The Discovery Season 3 Trailer
2. Michael Likes Book
Near the end of the trailer, buried in the rapid-fire shots of exciting episodes to come, we see Michael and Book share a kiss.
Not much is known about David Ajala's Cleveland "Book" Booker yet so we won't make any statements about Michael Burnham's taste in men, but after she accidentally fell in love with a secret Klingon assassin in Season 1, we hope she has better luck in Season 3.
Regarding Book though, it's entirely possible his name (or rather naming convention) is the same established in the Short Treks' episode "Calypso". That short also took place in the distant future and featured a character named Craft, a nickname used in day to day life, but not the character's true name.
