The Chrysalis (E02)

As the Heaven’s Gate "Classroom" begins, Bonnie and Marshall – who call themselves "Ti" and "Do" or "The Two" – enforce strict rules of no family communication. After Ti dies from cancer in 1985, a distraught Do briefly allows members to visit their families, and a few consider leaving the group for good. When the members return, Do becomes much more controlling – and opens the door to group suicide. (HBO Max)
