Stefan

Stefan is a friendly glowing one in the CEO offices of the Red Racer factory

Effects of player's actions
Since the Surgeon "reprogrammed" its mind, it is non-hostile unless the Lone Wanderer kills its master. He is not affected by the "Disable Chips" instant-kill effect that can be triggered by two of the terminals in the area.

Appearances
Stefan appears only in Fallout 3.

Bugs
After killing the Surgeon, Stefan will occasionally not turn hostile like he normally should.
