‘The Inner Fight’ is the penultimate episode of Lower Decks season 4. It’s appropriately titled. Trapped in a cave on an alien world by actual literal knife rain, Beckett Mariner (the amazing Tawny Newsome) opens up to her opponent cum confidant, Klingon Ma’ah (Jon Curry). As she does, she articulates the problem at the core of Starfleet, one that’s been around as long as the organization itself. One that touches on each person to wear the badge and head out into the unknown.
