Lenk's Bad Debts

Lenk's Bad Debts is an unmarked quest

Quick walkthrough
On their first meeting, Comm Officer Lenk will mistake the Courier for an Omerta bailiff. For 250 caps, a very small amount of NCR infamy (not enough to reduce a player's reputation) and evil Karma, the player can extort her. Alternatively, the Courier can pass a Speech check of 30 to hear her full story of how she is the sole survivor of her patrol, and the guilt issues led to her gambling debts. For good Karma, the Courier can assure her that she'll get revenge, and for evil Karma, they can call her pathetic.

The Courier may speak to Ranger Kudlow about Lenk afterward, and Kudlow will explain some more details.
