Ep 13. Terminus (1)

In the season 20 finale of Doctor Who, the Doctor and her companions arrive at a mysterious space station called "Terminus". Upon their arrival, they find the station is almost entirely devoid of life, apart from a few sickly inhabitants. The Doctor uses her medical skills to help treat the sick and quickly realizes that they are suffering from a deadly virus.

As the Doctor and her companions investigate further, they discover that the space station is actually a quarantine zone for those afflicted with the virus. It soon becomes clear that the virus is not a natural occurrence and has been deliberately engineered by an unknown entity. The Doctor must race against time to find a cure for the virus before it spreads beyond the confines of the space station and infects the wider universe.

Meanwhile, two dangerous forces are also at play on Terminus. A group of space pirates, led by the charismatic Captain Wrack, have boarded the station with the intention of looting it. They quickly realize they are not alone and are soon at odds with the Doctor and her companions. Additionally, a shadowy figure known only as "Black Guardian" is also present on Terminus, monitoring events from the sidelines and manipulating events to suit his own mysterious agenda.

Throughout the episode, the Doctor must navigate these various threats and contend with the emotionally charged situation on Terminus. Her own companions begin to question her leadership and motives, adding another layer of tension to the already fraught situation. The Doctor remains undeterred and relentlessly works to find a cure for the virus, eventually unraveling a shocking mystery that shakes the very foundations of the space station and the wider universe.
