Doctor Lesko

Dr. Weston Lesko is a scientist living in Grayditch in 2277.

Background
Lesko is responsible for creating the fire ants that carried off or killed almost everyone in Grayditch. He was experimenting on giant ants, trying to return them to their normal size through genetic manipulation when he accidentally created the fire ants. Despite the death and destruction his experiments caused, Lesko has remained indifferent to the lives lost, stating, "At the cost of a few, generations shall be saved".

Daily schedule

 * Until the quest Those! is completed, Lesko can be found deep underground in the Marigold Station. He will usually be in his laboratory outside the hatchery, or he might flee a short distance into the hatchery itself.
 * Lesko will not return to his shack until Those! is fully completed. This means you must also find a home for Bryan (or refuse to do so) and receive the experience points for this quest before Lesko will return to his shack.

Quests

 * Those!: Doctor Lesko requires the player's help to regain control of his experiment. If the player has a high enough Science skill and Intelligence, an additional dialogue option appears when asking Lesko about his experiments. When chosen, Lesko reveals that he has been using FEV in his experiments. An additional dialogue option will also appear if the player has chosen the perk Entomologist, which upsets the doctor slightly.
 * Nectar Collecting for Fun and Profit: After completion of "Those!", Lesko will pay for samples of fire ant nectar. Be aware that entering Doctor Lesko's shack will be considered trespassing, even though you might have to enter it to give him some nectar. Stay there for too long, and both the protectron and Doctor Lesko will open fire on you.

Notable quotes

 * "What a distressing development!!"
 * "I will blind you with science!" (when hostile via Mesmetron)
 * "Science always triumphs!" (when hostile)
 * "You've manifested yourself!"( when hostile)
 * "Your arrival was most unexpected, but not entirely unwelcome"

Appearances
Weston Lesko only appears in Fallout 3.

Behind the scenes

 * Lesko may be named after James R. Lesko, a character from the film Phase IV, who is also a scientist who has to deal with "ant problems."
 * If Lesko turns hostile, he may shout, "I will blind you with science!" - a possible reference to the Thomas Dolby song, "She Blinded Me With Science".
