Carlos

Carlos is a homeless man sitting across the bridge from Rivet City.

Related quest: Water Beggars
He is asking for Purified Water. If the PC decides to give him purified water, they will gain +50 Karma. If you refuse to give Carlos any water, you will later find his dead body at the same location he was.

Glitches
If you find the bridge to Rivet City extended before you speak to the intercom and you scare Carlos to run across the bridge, then speak to the intrcom and the bridge will dissapear. Carlos will fall to his death or fall into the water. The bridge will continue to move across, and the PC can then go into Rivet City.

Appearances
only appears in Fallout 3.
