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 two first 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. He, his father, and the other dwellers were attacked by Fire Ants. 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.

Find the source of fire ants
In the Marigold Metro Station you need to find the cause of the Fire Ant infestation. Instead you will find Doctor Lesko who gives you quite a scare, working down in a maintenance room. He explains to you the reason of the Fire Ants' behavior and how they gained ability to "spit fire". You can choose to help him reverse the effect or deal with the Fire Ant Queen yourself.


 * You will find the Fire Ant Queen through the other door in Dr. Lesko's lab, in the Queen Ant's Hatchery.

If you follow his instructions and kill only the Fire Ant Nest Protectors guarding the Fire Ant Queen you will receive a prize - a choice of either the Ant Might or the Ant Sight perk. With a Speech check or high enough Science skill you can kill the Fire Ant Queen and still get one of the perks. You can also hold off killing the queen until after you choose your prize, then run down to the queen and kill her if you want to. At that point Doctor Lesko will also be running around in the queen's chamber, making a possible second target. You are awarded positive karma for killing the Fire Ant Queen. Afterward, if you talk to Doctor Lesko he seems oblivious to the queen's death and not upset at all toward you. If you frenzy the queen she will attack the robot and he will help you kill her. Another easy way to kill the Fire Ant Queen is to get close to her with a melee weapon and continue circling around her behind while attacking. Or a quicker way is to use 1 shot from the Fatman, the queen ant will die instantly (but be sure not to use the MIRV and waste 8 mini nukes cause she dies with one)

When speaking with Doctor Lesko about doing the ants task, 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.

If you kill Doctor Lesko you lose Karma. On his corpse is a N99 10mm Pistol and the password to his computer, as well as a standard +5 Science lab coat.

If you hack Doctor Lesko's terminal near the Fire Ant Queen (don't forget to grab the Big Book of Science beside the terminal), you can send the Inhibitor Pulse yourself and destroy the mutagen sample he is using (FEV). If you choose to destroy the mutagen sample, you have to convince him with a Speech Check, or sufficient Science (75) skill, that it was for the best, otherwise he will call you an utter buffoon. The rewards for the quest seem to be the same, although you gain more Karma for destroying the mutagen sample and convincing Doctor Lesko that it was the right thing to do. If you miss the Speech Check Doctor Lesko voids your reward or if you have high Science skill you can convince him that was the right thing to do. Behind the terminal is a Nuka-Cola Quantum.

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 can then also decide to help him find a place to live. Bryan will tell you his cousin Vera Weatherly owns The Weatherly Hotel in Rivet City. You just need to ask her about Bryan Wilks and she'll agree to take him in. You will need to go back to Grayditch and tell Bryan that he can move in with his cousin.

It's also possible to convince the Mayor of Little Lamplight to let him stay there. 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. On the Xbox360 version, the option to discuss Bryan's relocation with Vera Weatherly will still be available despite having discussed it with MacCready.

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. He will give you a collar to put on the person. You then trick Bryan into putting on the collar, and explain that it will guide him home. The quest will be completed, experience points will be given, caps from Eulogy and a negative Karma. However, for some reason Bryan never makes it to Paradise Falls and choosing this option will make Bryan disappear instead.

You can also convince Bryan to live in Grayditch by himself. Doing so will bring the quest to completion. At some point after you have finished with the Fire Ant Queen, but before you find a place for Bryan to live, Bryan may move back into his old house.

As long as you do not sell him to the slavers (you still the xp for selling him on the 360) or tell him to fend for himself you get the 300+ experience points.&#160;

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.
 * This encounter maybe a nod to Oblivion, in particular, the city of Kvatch. Upon approaching the city of Kvatch (or rather the refugee camp of it) the player encounters a fleeing Altmer (High Elf) that tells the player to "Run for your life" and that "They burned the whole city (Kvatch) to the ground".
 * You can also accuire the quest by looking in the Recently Built Shack (Average lock) in Grayditch, then by hacking into the doctor's computer. (Xbox 360 version)

Bugs

 * 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 accidentally (or intentionally) 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.


 * 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. (I was able to kill 2 Guardians by making them Frenzy, and still completed the quest on PC)


 * If the Fire Ant Queen sees you, she may teleport in front of you as you are leaving the cave (360, PS3 &amp; PC)


 * Additionally, if you start fighting the Fire Ant Queen and try to leave, there is a chance she will follow you, which may result in her getting stuck in the rocks where she can't fit through the passage. If this happens, she will continue to move through solid rock until you can "lure" her out into the open again. While this glitch is occurring, you can only target the exposed parts of the queen in V.A.T.S.


 * If hit with the Fire Ant Queen's spit while in the middle of the spitting animation, you may be knocked out of it and the game subsequently reports a [DANGER] message when crouched out of sight of the Queen or any Guardians. Then after roughly 10 seconds, you may encounter the Queen teleport bug and started taking damage.


 * 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.


 * If the Fire Ant Queen is killed for one reason or another, even though Lesko appears oblivious to her death in dialogue, out of dialogue he can be heard saying "Time to start back at square one".


 * After completing the quest and finding Bryan Wilks a new home, Three Dog will comment on GNR radio that you have done so, but he still says 'ok, it seems like settlement of Greyditch has gone quiet' as if he didn't know about the quest.

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 eating monsters. The heroes of the film burned the ants to death. A tagline for the movie was to "Shoot at their antennae!"
