Player acquires Measles as a companion

Player acquires Measles as a companion was going to be a quest in Van Buren, the canceled Fallout 3 by Black Isle Studios. It is located at Reservation.

Walkthrough
If the player agrees to help Willem and be the ghouls' ambassador of "good will," either through Measles, Willem himself, or Colonel Green, Willem will ask the PC if he would be interested in taking Measles along so he may experience the outside world and be a ghoul representative/advisor to the PC in case there are questions about the ghouls the PC would not know how to answer. If the player agrees to take Measles, there you go. If not, the offer will stand for as long as the player is friendly with Willem.
