Those ! Those ! is a side quest in " Fallout 3 " . It is also a Xbox 360 / PC achievement and PlayStation 3 trophy . A small boy named Bryan Wilks will approach the player as they come into the vicinity of Grayditch ; this includes Super - Duper Mart or Sewer Waystation , but can be as far as Wilhelm ' s Wharf . He will then ask the player to help him find his father , Fred Wilks , who seems to be trapped in the town infested with fire ants . Detailed walkthrough . During the first two stages of the mission , Bryan will be hiding in the Pulowski Preservation shelter near the diner . Find Bryan Wilks ' s father . Bryan Wilks will approach the Lone Wanderer in the area outside Grayditch , where he tells them that he , his father , and the other dwellers were attacked by fire ants . He then asks the player to look for his father in the town . The father ' s body can be later found in his house by the shack , killed by the fire ants . The player can loot a Chinese assault rifle and some ammunition off the shelf in the house and the shack ' s key from the body of Bryan ' s father . In the shack , the player can find Doctor Lesko ' s equipment and terminal . Read the notes on the terminal to receive the Marigold station location and the option to proceed there to locate the source of the fire ants . Also , with a mildly challenging Speech check or the Child at Heart perk , the Lone Wanderer can convince Bryan to give them the key to a dumpster behind the diner with some pretty valuable loot if they are at a lower level ( a number of pulse grenades , a scoped . 44 Magnum , and some medical supplies ) . Find the source of the fire ants . While searching the Marigold metro station for the cause of the fire ant infestation , the player instead finds Doctor Lesko working in a makeshift laboratory . He explains the origin of the fire ants , particularly their ability to spit fire . The Lone Wanderer can choose to help him reverse the effect or deal with the giant ant queen themself . When speaking with Doctor Lesko , if the player asks for a " serious incentive , " he will offer his old lab coat along with bonus perk s . Lesko ' s lab coat provides + 20 Radiation Resistance and + 10 Science . The player will find the fire ant queen in the queen ant ' s hatchery , beyond Dr . Lesko ' s lab . It is guarded by numerous fire ant nest guardians . Find a place for Bryan Wilks to stay . First , talk to Bryan and tell him about his father ' s fate and the fire ants . He is located in the Pulowski Preservation shelter to the right of the diner in Grayditch . The player is then given the option of helping him find a place to live . Bryan will tell the Lone Wanderer that a cousin of his lives in Rivet City . He is talking about Vera Weatherly , owner of the Weatherly Hotel . The player only needs to find her and mention that Bryan needs a place to live and she ' ll happily agree to take him in . The player is awarded considerable positive Karma for choosing this option . With the arrangement made , simply return to Grayditch and tell Bryan that he can move in with his aunt ; he will agree to move out there , and the quest will end . When the player returns to Rivet City , Bryan will be there . It ' s also possible to convince the Mayor of Little Lamplight to let him stay there , either with a speech check or via the Child at Heart perk . Be forewarned that discussing this option with the Mayor will prevent the dialogue option for Bryan ' s relocation from appearing with Vera Weatherly , closing off that path even if Bryan has not been told of his potential new home . Since this is not as good an arrangement for Bryan , no Karma will be awarded either way . Alternatively , the player can go to Paradise Falls . Talk to Eulogy Jones , and tell him they have a child for sale . He will offer 100 caps initially , but one can receive 300 caps if the player passes a speech check . The Lone Wanderer will receive a considerable amount of negative Karma for this despicable act , and Eulogy will give them the agreed - upon number of caps and a collar to put on the hapless youngster . The player will then trick Bryan into putting on the collar , and explain that it will guide him home . Again , the quest will be completed and experience points will be given . Bryan will not be seen again , even though Three Dog will mention that he is at Paradise Falls . The player can also tell Bryan that they are unwilling to find him a place to live ( or never offer to in the first place ) , which will end the quest immediately . Bryan will move back into his old house and live in Grayditch by himself . No Karma will be gained or lost . However , this option is irreversible , even if the player has a change of heart later . For example , even if the player encounters Vera Weatherly later in the game , the dialogue option for getting her to take Bryan in will not even appear . As long as the player does not sell him to the slavers , they get the 300 + experience points ( XP is still rewardable for doing this on the 360 and the PS3 ) . Finding Bryan . Bryan usually finds the player , most often on their first trip to Super - Duper Mart . If he does not , or if he approaches the player while they are in combat and gets scared off , here are the other places they " may " find him :
