Michael Burnham is back and giving all the hugs after having spent a year kicking around some part of the galaxy with Book and (Queen) Grudge.
With the Discovery crew reunited, Stamets jumps the ship to the Sol System where it turns out Earth is still a utopia! Except it's also an isolationist state, disconnected from both the Federation and its former colonies, hell bent on protecting itself at the cost of its neighbors.
"The People of Earth" introduces us to the new-old Earth government in the form of the United Earth Defense Force and a new character, Adira. The episode serves as yet more reset-button pressing, positioning Saru as captain of the USS Discovery and Michael as first officer. We get a nice visit to Earth and a couple more nuggets of info about what exactly is happening in this crazy thing called the 32nd century, before we're shoving off again to try to track down the Federation remnant.
As always, we've got numerous callbacks and a few hints about this brave new world, so here's our list of everything we caught in Star Trek: Discovery, season three, episode three: "People of Earth".
