The Lost Initiate

 is an unmarked Fallout 3 quest.

During a training exercise in Falls Church, Knight Church, Paladin Hoss, Initiate Pek, and an unnamed Paladin (RefID=15595) were separated during a Super mutant attack. Knight Church was killed in the initial attack and Initiate Pek became trapped in an office building while Paladin Hoss and the other Paladin were fighting nearby. Paladin Hoss will inform you that Pek has barricaded himself inside a janitor's closet towards the back of the first floor and request your assistance in reaching the office building where Pek is located. Once complete, you are asked to storm the building and rescue Pek, who is cowering in a corner due to a gun jam. With sufficient Small Guns or Repair skill, Pek's gun can be fixed; regardless of weapon status, Pek will follow you until you exit the building and regroup outside with Paladin Hoss.

Possibly related, two dead Brotherhood of Steel Initiates can be found with two supermutants in the other office building in Falls Church.

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 caps 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.
 * When you first talk to Paladin Hoss, you have the option of telling him to "Fuck off," which will net you negative karma. If you talk to him again, you are presented with the same options as before, and can once again tell him to "Fuck off." You can continue doing this ad infinitum as an infinite source of negative karma.
 * 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.
 * Similar to above he may be dead with armor in inventory but not on.
 * Sometimes if Paladin Hoss dies while waiting outside for you to retrieve initiate Pek, initiate Pek will emerge from the office building dead.
 * If Paladin Hoss dies in combat while pushing through to the building, Pek might not be alive in the closet and is stripped of everything. He'll have a Combat armor in his inventory, though.
 * Sometimes when Hoss has a rocket launcher he will fire continiously even after all mutants are dead, causing harm to himself, and your followers, maybe eventually killing you in the blast. (fix reload area)
