Saru tries to bring the crew together over food, and doesn’t entirely succeed, while Burnham brings Adira to Trill in the hopes of getting her groove back, and does entirely succeed, though not due to any help from the recalcitrant Trill. My review of Star Trek: Discovery‘s “Forget Me Not.”
Culber is beautifully used here, as he’s in a unique position, having died and come back. He’s already had everything he knows taken away from him in a much more devastating manner. It’s why he gives the advice to Saru he does, and also why he suggests that Burnham be the one to take Adira down to Trill.
