"After It Happened" is a 1988 episode of the NBC television series Midnight Caller. The controversial episode tells the story of a bisexual man who is deliberately infecting people, including series lead character Jack Killian's ex-girlfriend, with HIV. AIDS and LGBT rights activists disrupted filming, citing concerns over the negative portrayal of bisexual and HIV-positive people and fears that the show would make people with AIDS the targets of violence. Series executives made some changes to the script in response to these concerns, but activists were still displeased. "After It Happened" performed well in the ratings but received a mixed critical response. Actress Kay Lenz received an Emmy Award for her guest-starring role as Killian's ex-girlfriend Tina. NBC aired a follow-up episode in 1989 in which Tina is near death. This second script, "Someone to Love", was written in consultation with some of the groups that protested "After It Happened" and was much more favorably received.
