Star Trek Discovery Season 3 Episode 11 “Su’Kal”
Discovery detects a life sign on the starship in the highly radioactive Verubin Nebula, and Saru suggests that this could be the child of one of the starship’s scientists.
They jump there to investigate, and find a planet made primarily of dilithium inside the nebula. Saru, Burnham, and Culber transport to the planet, leaving Tilly in command of Discovery.
Bad idea. Tilly is wholly incompetent, and by the end she has lost control of the ship.
What a mish-mash of the weird and incomprehensible. Possibly the worst writing yet.
