ED-E (Lonesome Road)

ED-E is a companion living in the Divide in the Fallout: New Vegas add-on Lonesome Road.

Background
At first glance the Courier mistakes the robot with ED-E, whom plays music from the movie Ralphie. With an Intelligence of 6, the Courier deciphers the beeps and garble and realizes that the silo has "pretty advanced engineering capabilities" since it was able to remote-scan ED-E from the Mojave Wasteland and create copies within the Divide.

Upon joining the courier's party, the ED-E copy starts playing a log from Dr. Whitley, and continues doing so at certain "checkpoints" during the trip through the Divide.

Appearances
The copy of ED-E appears only in the Fallout: New Vegas add-on Lonesome Road.
