Prosper

Prosper is a slave found at the train tunnel in 2277.

Background
Paranoid, nervous, and usually careful, Prosper was a smuggler, ferrying several large cargos of ingots from the steelyard of The Pitt to outlying areas. His operation was eventually compromised and his crew either captured or killed. The survivors were sold to slavers heading towards Paradise Falls. 

Quests

 * Into the Pitt: The Lone Wanderer can buy him and the other slaves in the slave pen from Ramsey or the Lone Wanderer can kill all the slavers to get the key to open the pen. After either option the Lone Wanderer can then talk to Prosper and take his clothes from him or take the clothes from the dead slave in the corner.

Appearances
Prosper appears only in the Fallout 3 add-on The Pitt.

Behind the scenes

 * If the player asks Prosper for the clothes off his own back the dialogue option reads, "Your clothes. Give them to me. Now." This is a reference to a recurring line in The Terminator movie series.
 * His name is fairly ironic. Prosper vaguely means to have good fortune and a happy life, which is obviously not the case when he is encountered.
