This episode has the longest opening sequence of the enitre series at seven minutes and fifteen seconds. Being a two-parter the time is filled with a recap of the previous episode which was adopted for series 4 and 5 when airing two part episodes.
99 gives birth to twins, a boy and a girl. Although the babies' names are never actually revealed in the series, it is quite likely the boy grows up to be CONTROL agent Zach Smart (Andy Dick) the star of Fox's 1995 revival of "Get Smart". The fate of Max and 99's daughter remains a secret.
