Complete story — includes the ending

In the wake of the death of Gene, Sally begins to misbehave in class, much to Betty and Don's dismay. Betty and Don meet with Suzanne to discuss the matter; Suzanne later calls the Draper house late at night, appearing smitten with Don. Pete learns that Admiral, a television company whose sales have plateaued, are selling well among African-American customers. He devises a plan for Admiral to buy up cheaper ad space in African-American publications, but the company representatives are deeply opposed to the idea. Duck invites Peggy and Pete to lunch in an effort to recruit them; he reveals his knowledge of their affair and believes that Pete helped Peggy's career, but they both deny it. Peggy later meets with Don to discuss getting a raise, but he brushes her off, citing Lane's strict cost-cutting measures. Don takes Betty to the hospital when she goes into labor; Betty is given heavy pain medication and hallucinates encounters with both of her parents, as well as the recent assassination of civil rights leader Medgar Evers, which is all over the news. Betty ends up giving birth to a baby boy, whom she names Eugene in honor of her father.
