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 by 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 Intiates 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.

 * Pek, Hoss, and the Paladin can all die. If that happens you will not be rewarded.
 * If you take too long to rescue Pek, the room he's hiding on may be locked (very hard) and he may be killed and stripped mostly clean.
 * The easiest way to prevent Hoss from dying (and losing the XP) is to clear all the mutants in the immediate area before talking to Hoss; once the way is clear you can trigger the event and follow him to the building entrance.
 * You may wish to save before you enter the area; Hoss wields a flamer, and has a habit of being gunned down while trying to charge the Super Mutants with it.
 * If you still want to gain the XP and the Power Armor Hoss and the Paladin would normally drop after being massacred by the Super Mutants, clear the area completely of Super Mutants before speaking with Hoss. After saving Pek and accepting no reward, all three will follow you around (sometimes even all the way to Megaton). Head NE to where a large truck is stuck in the rubble and have them line up along side of it. Shoot the truck until it explodes (normally, you should survive) and then loot their dead bodies.
 * If you are skilled in the Repair or Small Guns skills, you get a unique dialogue options to fix Pek's broken weapon.
 * If you enter Falls Church once (from Marigold Station), the Brotherhood/Supermutant battle begins. If you go back to the Marigold station and return later, everyone (including Hoss and Pek) is already dead and there is no way to finish the quest. It seems like they are unable to hold their own against the mutants if you don't help them.
 * In some instances, Pek will not run, but rather will sneak everywhere after being rescued. Not only does this make him a slow follower, but will also make him an easy target for enemies with ranged weapons.

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.
 * 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.
