Initiate Pek

Initiate Pek is an Initiate in the Capital Wasteland Brotherhood of Steel.

Unmarked quest: The Lost Initiate
During a training exercise in Falls Church, Pek, Paladin Hoss, and a unnamed Paladin (RefID=15595) were separated by a Super Mutant attack. Pek became trapped in an office building while Hoss and a Paladin were fighting nearby. Vault 101 Dweller soon arrives and aids Hoss and the Paladin and they eventually push to the office building where Pek is located. Hoss and the Paladin secure the area outside while the Vault 101 Dweller storms inside the building killing the Super Mutants inside. He soon finds Pek hiding and cowering in a corner. The Vault 101 Dweller repairs Pek's weapon and they regroup outside with Hoss and the Paladin.

Bugs

 * Pek and Hoss will likely become 'stuck' on the player after successfully rescuing them and will show up in your home in Tenpenny Tower or Megaton every time you sleep there, or any other unlikely place.
 * They are also known for stealing items from the locker next to the "kitchen" in your Megaton house (since it is not correctly set to be owned by the player) if this happens.
 * They will keep doing this until they get killed, which will happen eventually. (At which point if you had been following them you can loot their corpses with no karma hit.)
 * To avoid this bug, simply ask for payment when talking to Hoss for the first time. This has no karma effect and will make Pek and Hoss not follow you after rescuing the initiate.
 * Special Note: It is also possible to complete this mission successfully only to have Pek respawn inside the office if you return at a later time. He may begin following you all over again (confirmed on 360), or simply cower and be grateful (PS3).
 * If you want to make them productive members of your group, you can add items to their inventory by reverse pickpocketting them. While you cannot talk to them to manage inventory, they can at least carry a gun, armor, and stimpaks that you can retrieve when they die.
 * If you managed to rescue Pek before talking to Hoss, the game will probably crash when you leave the building. (I can confirm that in pc version it doesn't crash. Just Pek follows me all the time no matter what...)
 * Pek sometimes turns out to be dead in the building before you enter it and Hoss will not pay you your caps.
 * After so long of not finding the quest, you will find Hoss, Pek and the Paladin dead in the office buildings, and you are unable to receive any reward. (XBox360)(Confirmed on PC as well)
 * In the event that Pek follows you indefinitely, he can be equipped with weapons, armour and stimpacks which he will sometimes use, however it appears impossible to get him to leave you alone without killing him and gaining negative karma, or allowing him to die in battle. He may also appear a considerable distance away from a location when fast travelling, arriving a minute or so after your arrival.
 * Sometimes, he will crouch when not moving.
