Talk to Katrina

Talk to Katrina is an unmarked quest in Fallout.

Quick walkthrough

 * 1) Travel to Shady Sands.
 * 2) Exhaust all dialogue options with Katrina.

Detailed walkthrough
Katrina is the town greeter standing at the front entrance to Shady Sands. The likely intention of the developers of Fallout was to include her as a tutorial character considering her dialogue is focused around explaining a few fundamental game-play systems, including bartering, healing, and the First Aid and Doctor skills.

This quest is very straightforward; exhausting all possible dialogue options with Katrina will yield an experience reward. Note that she will not talk to a character armed with any weapon, as she encourages peace and diplomacy in the small community.

Reward

 * 250 XP
