Brian Virgil

Virgil is a super mutant living in the commonwealth in the year 2287. Living initially in the rocky cave, he is part of the quest to get into The Institute.

Background
Virgil was a member of the institute at some point before 2287. He was working on an unknown project, but went rogue. He ecaped to the glowing sea. He infected himself with the FEV virus to aid in protection from radiation for his escape to the glowing sea.

Quests

 * The Glowing Sea: After heading through the Glowing Sea and talking to Virgil about needing his help, Virgil will ask to get an experimental serum that he claims will make him a human again, but isn't sure if it exists or not. The player character must agree to this if they want to complete The Glowing Sea and continue the main story line. The player character will have to go to the FEV labs in the Institute to retrieve the serum.

Effects of player's actions
After getting the serum, the player character has two options: If the player character gives Virgil the serum and waits for a week or two, they can go back and see that Virgil is now a normal human. He almost acts like it's no big deal, when it really is; he just found a cure to FEV. Albeit only one strain, and that it takes a week for it to take effect, Virgil claims that with continued research, he can possibly cure other FEV strains.
 * They can simply give Virgil the serum, and certain companions will act differently to this choice. For example, Piper would like it if you did, but Danse won't like it at all.
 * They can also lie to Virgil through a speech check, claiming that it wasn't there, which will prompt him to commit suicide.

Appearances
Virgil appears only in Fallout 4.
