Grayditch

Grayditch was once a community on the outskirts of the D.C. ruins. Until recently, it was inhabited by a handful of survivors, including Dr. Lesko. The town has been taken over by a colony of mutated Fire Ants. The player is brought to Grayditch through Bryan Wilks, a boy who is the sole survivor of the town.

Much like Evergreen Mills, Three Dog will continue to discuss the "sudden silence" of Grayditch, regardless of the player's actions. Finishing Those! only adds a news report on how the player handled the Fire Ant infestation and whether the player found Bryan Wilks a foster parent.

Characters
Bryan Wilks appears to be the last civilian survivor of Grayditch. He contacts the player to save his father, who he fears is trapped or dead. Bryan will run up to the player when he is near Grayditch and beg for assistance, kicking off Those!.

Dr. Lesko worked in a small workshop next door to the Wilks' home. According to his computer archives, Dr. Lesko was involved with the accidental creation of the Fire Ants. Lesko hoped that he would be able to return the mutated ants to their original size through genetic re-sequencing. For some reason, batch A27 became a disastrous failure, and the ants overran the town. Dr. Lesko hid in a room in the nearby Marigold Station, where he continues his experiments. It is possible to acquire the Ant Sight (+1 Perception and fire resist) or Ant Might (+1 Strength and fire resist) perks from Dr. Lesko if you choose to help him destroy five ant guardians in the area without destroying the Ant Queen. If you push Dr. Lesko about what he will give you for completing that quest, he will add Lesko's Lab Coat to the quest reward.

Body of another inhabitant of Grayditch - William Brandice - can be found north of Doctor Lesko's Marigold Lab. On the body you can find a Wasteland Surgeon Outfit (Medicine +5). You also get the key to his footlocker in his Grayditch home containing a Missile Launcher and a Missile. His home seats right opposite to the Wilks'.

Another survivor of Grayditch can be found in Arefu. He is left of the bridge and after the 1st time you talk to him he just answer in panic about the fire ants attack.

Known Issues
In the PC version, this place causes a lot of crashes before the ants are eliminated, so save often.

On the xbox 360 version it is rare, but sometimes Bryan Wilks is no where to be found but this can be fixed by just entering the tunnel and finding the scientist.
