Star Trek: 18 Easter Eggs In The Lower Decks Season Two Trailer
15. Shax, His Replacement Uncovered
We are introduced to Lieutenant Shax's replacement, Lieutenant Kayshon, who greets the Cerritos bridge crew (including Paul F. Tompkin's counselor Dr. Migleemo) in metaphor, a distinguishing trait of his people, the Tamarians from TNG's "Darmok".
Though we're speculating that Kayshon is Shax's successor to the tactical station after the Bajoran lieutenant's spectacular death in "No Small Parts", that shot of the enthusiastic Pandronian earlier in the trailer shows the two officers together, hinting either at Shax's return or a flashback to a meeting before his death.
