Brian Virgil



Brian Virgil is a super mutant living in the Commonwealth in 2287. Living initially in the rocky cave, he helps the Sole Survivor find a way into the Institute.

Background
Dr. Brian Virgil was a member of the Institute at some point before 2287. He was working on an unknown project involving the Forced Evolutionary Virus and the creation of Super mutants in the Bioscience Division. Overcome with guilt from the pain and suffering he had inflicted on innocent people, he decided to leave the Institute and end the FEV program.. He then escaped to the Glowing Sea and infected himself with a unique strain of the FEV virus to survive the high levels of radiation.

Quests

 * The Glowing Sea: After heading through the Glowing Sea and being asked by the Sole Survivor for informations on the Institue, Virgil will ask the Sole Survivor to recover 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 quest and continue the main story line. The player character will have to go to the FEV labs in the Institute to retrieve the serum.
 * A Loose End: Unless convinced to spare him through a Charisma check, Kells will order the Sole Survivor to kill Virgil.

Effects of player's actions
After getting the serum, the player character has two options:
 * They can simply give Virgil the serum, and certain companions will react differently to this choice. For example, John Hancock, Piper, Nick Valentine, Codsworth and Curie like the player's choice to cure Virgil, but Danse won't like it at all; this is due to his teachings by the Brotherhood. Strong also won't like it as he prefers being a Super Mutant and is angry with the doctor's ambitions to cure the others.
 * They can also lie to Virgil through sequence of three speech check, claiming that serum wasn't there. Checks difficulty increases with each one. After first two checks player character still have the option to give serum to Virgil through breaking and reinitiating dialog with him. After third speech check Virgil requests the player character to kill him and Virgil's Cure will fail.
 * If the player character gives Virgil the serum and waits three days, they can go back and see that Virgil is now a normal human. After this, all the items inside the cave become available for looting.
 * If the player character is wearing a power armor helmet with a Targeting HUD mod when returning to complete the quest The Glowing Sea, the Sole Survivor will immediately fail the quest upon re-entering rocky cave with the serum. Remove the helmet before entering the cave.
 * If upon first entering and leaving the Institute, even if the player does not get the serum, the player character waits before bringing the serum to Virgil for around a week, Virgil is then found completely turned hostile and quest "The Glowing Sea" will immediately fail upon re-entering rocky cave.
 * If the player character destroys the Institute, Virgil will no longer want to speak with them and will ask them to leave. However, he will not turn hostile, no matter how long you stay in the cave.

Appearances
Virgil appears only in Fallout 4.

Bugs

 * There is a bug when returning the serum to Virgil that auto fails the quest and turns Virgil and his Protectron hostile if the cave is entered in power armor.
 * He will turn hostile even when returning to him once he is cured if the cave is entered in power armor.
 * This is caused by the "Targeting HUD" helmet upgrade (others upgrades may or may not affect this). Simply unequip the helmet on the power armor before entering the cave.
 * Unequipped the helmet with targeting enhancement, the quest did not auto fail.
