Save Killian's life

Save Killian's life is an unmarked quest in Fallout.

Detailed walkthrough
In the Crash House area of Junktown, go to the Darkwaters General Store. Talk to Killian Darkwater for a bit. Kenji should step in and attempt to assassinate Killian. If the Vault Dweller helps protecting Killian, it will open up the Get Gizmo's confession quest, which the Vault Dweller can accept or refuse.

Accept
Starts the Get Gizmo's confession quest immediately.

Refuse
Killian informs the Vault Dweller about information leak inadmissibility and offers going to jail peacefully. The Vault Dweller can agree or disagree with this. If the Vault Dweller agrees to go to the jail, Killian takes him to the jail. Andrew will release the Vault Dweller at midnight when Gizmo and Izo will be killed already. The Vault Dweller can bust out of jail himself before midnight. If the Vault Dweller doesn't agree, Killian and Junktown guards turn hostile.

Rewards

 * 400 XP
 * +2 or +3 Reputation (depending on whether or not you delivered the final shot to Kenji) if you agree to help Killian further or if you decline helping and don't go to jail.
 * -1 Reputation if you refuse to help and go to jail.

Bugs

 * Kenji will not do anything if you talk to Killian before he shoots, thus breaking the quest.
 * If Kenji is killed by a critical hit before you have a chance to attack, Killian will not initiate dialogue with you and will not start the Get Gizmo's Confession quest.
