Save Killian's life

Save Killian's life is a side quest in Fallout.

Walkthrough
In the Crash House area of Junktown, go to the Darkwaters General Store. Talk to Killian Darkwater and head for the exit. As you do so, a man named Kenji should walk past you and attempt to assassinate Killian. If you help Killian to kill Kenji, you will open up the Get Gizmo's confession quest.

Reward
