Those!

 is a Fallout 3 quest. It is also a Xbox 360/PC achievement and PlayStation 3 trophy

A small boy called Bryan Wilks will approach you as soon as you are in the vicinity of Grayditch - this includes Super-Duper Mart or Sewer Waystation, or as far as Wilhelm's Wharf.

He will ask you to help him find his father, Fred Wilks who seems to be trapped in Grayditch infested with fire ants.

Objectives and 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 you in the area outside Grayditch, where he tells you that he, his father, and the other dwellers were attacked by fire ants. He then asks the player to look for his father in Grayditch. The father's body can be later found in his house by the shack, killed by the fire ants. You can loot a Chinese assault rifle and some ammo off the shelf in the house and the shack's key from Bryan's father's body. In the shack you 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 mildly challenging speech check or the Child at Heart perk you can convince him to give you the key to a dumpster behind the diner with some pretty valuable loot for a lower level character.

Find the source of fire ants
Searching the Marigold Metro Station for the cause of the fire ant infestation, you instead find Doctor Lesko working in a makeshift laboratory. He explains the origin of the fire ants, particularly their ability to spit fire. You can choose to help him reverse the effect or deal with the fire ant queen yourself.

When speaking with Doctor Lesko, if you ask for a "serious incentive", he will offer his old lab coat along with the ant perks. Lesko's lab coat provides +20 Radiation Resistance and +10 science.

You will find the fire ant queen in the Queen Ant's Hatchery, beyond Dr. Lesko's lab.


 * Path 1: Kill only the fire ant nest protectors guarding the fire ant queen and return to Dr. Lesko for a choice of either the Ant Might or the Ant Sight perk.


 * Path 2: With a speech check or high enough science skill you can kill the fire ant queen and convince Doctor Lesko it's the best for humanity, and get one of the perks. You are awarded positive karma for killing the fire ant queen.

(Optional)
 * Hack the terminal in the hatchery to send an inhibitor pulse which will kill all fire ants found in the Grayditch area (excluding those in Marigold Station).
 * Hack his terminal in the hatchery to destroy the mutagen sample (FEV). You are awarded positive karma. Having done this, to receive the perk you must pass a speech check or sufficient science (70) skill to convince Lesko that it was best for humanity.
 * Kill Doctor Lesko and receive negative karma. Loot: Lesko's inventory. Same happens if you lie about the protectors being dead: he runs into the hatchery and you receive negative karma. The instant you enter the hatchery, he spontaneously drops dead and you receive the hacking objective.

Note that it is possible to get both of the rewards (lab coat and perk) and good karma (from killing the fire ant queen or destroying the mutagen sample) without passing the speech check. First, talk with Doctor Lesko for the "serious incentive". Then, go inside the Queen Ant's Hatchery, kill the 5 fire ant nest protectors but do not kill the queen. Go back to Lesko's lab and claim the rewards. Then go back to the hatchery, kill the queen or hack the terminal to destroy the mutagen sample. You will gain good karma in either way while keeping all rewards from Lesko.

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. You are then given the option of helping him find a place to live. Bryan will tell you that his aunt Vera lives in Rivet City. This is Vera Weatherly, owner of the Weatherly Hotel. You merely need to find her and mention that Bryan needs a place to live and she'll happily agree to take him in, with no Speech Check required. You will be 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 cousin; he will agree to move out there, and the quest will end. When you return 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.

Alternately you can go to Paradise Falls. Talk to Eulogy Jones, and tell him you have a child for sale. He will offer 100 caps initially, but you can receive 300 caps if you pass the speech check. You will receive considerable negative karma for this despicable act, and Eulogy will give you the agreed-upon number of caps and a collar to put on the hapless youngster. You 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.

You can also tell Bryan that you're 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 you have a change of heart later. For example, even if you encounter Vera Weatherly later in the game, the dialog option for getting her to take Bryan in will not even appear.

As long as you do not sell him to the slavers you get the 300+ experience points (you still get the XP for doing this on the 360 and the PS3).

Finding Bryan
Bryan usually finds you, most often on your first trip to Super Duper Mart. If he does not, or if he approaches you while you are in combat and gets scared off, here are other places you may find him:


 * Standing on a sidewalk in Grayditch: to the west of the diner, up a hill, and across the bridge in front of the Talon Company Camp.


 * The southern entrance to Scrapyard.


 * Granny's Shack at Wilhelm's Wharf near the river near Grayditch.


 * Talking to Doctor Lesko will also give you Bryan's location on your Pip-Boy.


 * You may encounter a wastelander telling you to "run for your life!" and that "they burned Grayditch to the ground!" The encounter does not give the quest, even upon entering Grayditch and the player must find Bryan Wilks or Doctor Lesko on his/her own to obtain the quest.


 * You can also acquire the quest by looking in the recently built shack (lock varies depending on your stats) in Grayditch, then by hacking into the doctor's computer. (Xbox 360 version and PC version)

Bugs

 * After completing the quest by sending Bryan to Vera, the screen text may say completed quest "Thos!" instead of 'Those!'.
 * If you locate Bryan Wilks' father before you find Bryan Wilks and then tell him you'll look for his father instead of picking the option to give him the bad news you won't be able to 'find' his father.
 * You should get the Ant Might/Ant Sight perk immediately when offered by Doctor Lesko. If you delay getting it until Doctor Lesko is back in his shack, you might not get the dialog option to get the Ant Might/Ant Sight perk.
 * Dr. Lesko's dialog trigger radius extends through his office door. Thus, his whole dialog tree can happen before you even open his door. This seems to be due to him standing near his computer a lot, which is near the door.
 * In several instances Bryan Wilks has appeared at the bridge to the Anchorage Memorial which has a long chain of mines on it, when he finally does track you down he will be missing an arm and will also have no dialogue whatsoever, all he does is follow you.
 * If you shoot Doctor Lesko during a scripted animation (e.g. bending over a microscope) he goes completely limp. He then runs two rooms away and through a solid wall, disappearing.
 * Bryan may not appear in the shelter and instead spawn in a inaccessible part of the map, making the quest unable to come to a conclusion. However, sometimes after talking to Vera, Bryan will be found in his home next to Lesko's shed in Grayditch, rather than in the shelter where you last left him, and the quest can be completed. This is not a glitch. After you talk to her, he can be found living in his home again while waiting for you to report on your search for a home.
 * Occasionally if you frenzy one of the Fire Ant Nest Guardians and they kill one of the others, it will not count towards the quest, and when you return to Doctor Lesko the only option is to lie; resulting in lost karma and no perks.
 * There are various bugs concerning the Ant Queen. Usually teleportation glitches in which the queen teleports to your location and often blocks your path through the tunnels.
 * If Lesko's protectron is killed inside of the subway, when you visit his shack it will be there and fall over dead as you enter.
 * The quest doesn't work if the player visits Marigold station and clears it of ants before starting. When prompted to return, the scientist will not be present and the queen ant unreachable. This may also be a result of approaching Grayditch from the wrong direction, skipping the initial trigger.
 * After killing the guardian ants but not killing the queen ant in "Those!" quest, after talking to the Doctor, he walks to the queen ant and then disappears.
 * When finding Bryan Wilks he may appear under the river unable to talk, which can be quite odd.
 * Bryan's father may not have key for the shack, and finding his body won't trigger anything.

Behind the scenes

 * This quest was inspired by the 1954 SciFi horror film Them!, a story about early New Mexico atomic tests that cause common ants to mutate into giant man-killing ones.
 * Bryan will occasionally make comments from inside the fallout shelter. One of these comments: "Now I know what a TV dinner feels like," is a reference to "Die Hard," in which Bruce Willis says the same line while crawling through a ventilation shaft.
