Since the debut of Star Trek: Lower Decks in 2020, Ensign Beckett Mariner (now a Lieutenant Junior Grade) is a capable, heroic Starfleet officer who sabotages herself. Over four seasons, Mariner made peace with her mother, Captain Freeman, and made friends with Brad Boimler, D'Vana Tendi, Samanthan Rutherford and new Vulcan crewmember, T'Lyn. However, Mariner has a big hole in her heart, and "The Inner Fight" offers real clarity. Mariner is so against promotion and advancement because of her connection to the Star Trek: The Next Generation episode "Lower Decks."
