The Lost Initiate

 is an unmarked Fallout 3 quest.

Upon your first visit to Falls Church you find an ongoing battle between a Brotherhood of Steel training squad and a group of super mutants. Knight Church has been killed and Initiate Pek is trying to hold out for reinforcements in a nearby building, Paladin Hoss will inform you. Pek has barricaded himself inside a janitor's closet towards the back of the first floor. You can choose to help rescue Pek or leave him to his fate.

Rewards

 * You are awarded XP for helping Pek (amount of XP varies between 250-350 points).
 * If you ask Hoss for payment you will receive money when you have rescued Pek but will not be awarded any Karma.
 * If you do not ask for payment you will receive good Karma instead and Hoss as well as Pek will join up with you and help you clear out the area.

Bugs

 * Paladin Hoss and Pek suffer from some rather nasty AI bugs when following you around. Please refer to their pages for more detailed information.
 * It has been reported that the Brotherhood of Steel squad may not appear at all, preventing the completion of this quest.
 * They may also be dead when you arrive there. (went through the tunnels from Grayditch)
 * Sometimes if Paladin Hoss dies while waiting outside for you to retrieve initiate Pek, initiate Pek will emerge from the office building dead.

Exploits

 * Infinite negative karma: If you say the line that involves dropping the F-bomb you will gain negative karma immediately after you exit the conversation. This action can be repeated as many times as desired.
