Doctor Lesko

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

Background
Lesko created 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 complete, Lesko can be found deep underground in the Marigold Station.
 * Lesko will not return to his shack until Those! is fully completed. This means you must also find a home for Bryan and receive the experience points for this quest before Lesko will return to his shack.

Related quests
He is involved in the quest Those! which can be obtained from him or alternately you will be approached by Bryan Wilks who will trigger this quest. Doctor Lesko's quest offers either Ant Sight or Ant Might as a reward, the player can choose between the two.

Other interactions
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 however only upsets the doctor slightly.

Appearances
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".
