This episode has a lot going on in it. An alien sphere that stops Discovery in it’s track, witty and ascerbic banter between Engineer Jett Reno and Lt. Commander Paul Stamets, the possible impending death of a beloved character, and a danger message from the mycelial network. All that, plus a very brief first-time appearance of Number One (Rebecca Romijn). Enjoy!!
