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. It is unknown when or how Virgil was mutated into a super mutant.

Interactions with the player character
After joining the Institute, Virgil will ask you to get an experimental serum that he claims will make him a human again, but isn't sure if it exists or not. If the player agrees, they will have to go to the FEV labs in the Institute to retrieve the serum. After getting the serum, the player has two options: If the player 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.

Effects of player's actions
If the Sole Survivor has found the serum in The Institute but lies about it upon returning to Virgil, he can be talked into killing himself.

Virgil appears only in Fallout 4.
