Episode 7 of "Jeremiah"
s01e07 City of Roses

Jeremiah and Kurdy travel in search of more information on the Big Death and Valhalla Sector. They rescue a rape victim from skinheads and take her to Thunder Mountain. This seems to trigger off childlhood memories of his parents' death for Kurdy. After Jeremiah helps the victim come to terms, he drops Kurdy off at his childhood apartment where he meets his childhood babysitter. Jeremiah goes to visit a doctor doing research on a vaccine for the Big Death, whose test subjects died earlier (in "The Bag"). Kurdy soon remembers first that his father shot his mother, and then that she did so at his mother's request because she was dying of the virus: Kurdy's father killed his wife and then shot himself.
