Theo

Theo is a recently-dead member of Reilly's Rangers in 2277.

Background
Reilly's private terminal explains that Theo was on a temporary contract to the Rangers, and that this mission would be the deciding factor as to whether he was accepted as a permanent member. His role before his death was mainly helping out around the base and transporting ammunition. He was the quartermaster of Reilly's Rangers. Reilly reveals that Theo was killed by a stray frag grenade as they were making their way to the roof of the hotel. According to Reilly's terminal, Theo was born in 2255.

Effects of player actions
Theo's corpse can be found in a stairwell in the Statesman Hotel. His ammunition box can be looted (during the quest) if Reilly gives the player the code (Reilly9090). Inside are 200 5mm rounds, 100 5,56mm rounds, 100 10mm rounds, and 4 frag grenades. If the ammunition is taken from the cache, the player can either keep it or share it with the other members of Reilly's Rangers on the roof of the Statesman Hotel.

The ammunition box code can also be Reilly0247

Appearances
Theo appears only in Fallout 3.
