Alex Dargon

 is a young eager scientist working on Project Purity. He can be found in the Citadel or the Jefferson Memorial, depending on whether the player has the Broken Steel download.

Background
Alex was always wondering what the scientists were doing when he was younger. Madison Li took him under her wing, and taught him what he knows today.

Dargon is a scientist in the Citadel, known for being a specialist in growing naturally occuring foodstuffs.

If he survives The Waters of Life he will remain in the Citadel forever, along with Daniel Agincourt and Madison Li, unless the player has Broken Steel downloaded, where he can be found working at Project Purity.

Interactions with the player character
During the quest The Waters of Life, Alex Dargon is one of the characters relocating to the Jefferson Memorial. After The Waters of Life, he can be talked to, yet he has few text options.

Appearances
appears only in Fallout 3.
