What Happened To L’Rell On Star Trek: Discovery
L’Rell Was Last Seen In Star Trek: Discovery Season 2
Star Trek: Discoveryseason 1 told a slow-burn story aboutL’Rell rising to become Chancellor of the Klingon Empire. L’Rell was introduced as a follower of T’Kuvma (Chris Obi), the self-styled Klingon Messiah. Left for dead along with her lover, Voq (Shazad Latif), L’Rell cunningly worked her way into a position of power and influence among the Klingons. L’Rell eventually allied herself with Michael Burnham (Sonequa Martin-Green) to save Qo’noS from a hydrogen bomb that could have destroyed the planet. L’Rell ended the war by rising up to become Chancellor.
Voq was surgically altered to resemble Starfleet Lt. Ash Tyler, and Tyler retained his human form to become commander of Section 31 in Star Trek: Discovery season 2.

InStar Trek: Discoveryseason 2, L’Rell fended off threats to her power as Chancellor among the Klingons.L’Rell and Ash Tyler hid their son, Tenavik (Kenneth Mitchell) on Boreth, where Tenavik grew to become a monk who showed Captain Christopher Pike (Anson Mount) his tragic destiny thanks to a Klingon time crystal. L’Rell’s last appearance was leading the Klingons to defeat Section 31’s genocidal A.I., Control, as the USS Discovery permanently jumped to the 32nd century at theend ofStar Trek: Discoveryseason 2.
