Virgil’s serum, within the context of Fallout 4, is an experimental cure designed to reverse the effects of a modified Forced Evolutionary Virus (FEV). Specifically, it aims to revert Virgil, a former Institute scientist, from his Super Mutant form back to a human. The serum works by counteracting the specific alterations made by Virgil’s unique strain of FEV, effectively rewriting his cellular structure to its original human template.
Understanding the Science Behind the Serum
The Forced Evolutionary Virus (FEV) is a recurring element in the Fallout universe. It’s a mutagen that, under the right conditions, can transform humans into Super Mutants. These beings typically possess enhanced strength, durability, and longevity, but often at the cost of intellect and physical appearance. Virgil, however, engineered his own version of the FEV. This modified version granted him significant radiation resistance, a crucial adaptation for surviving in the highly irradiated Glowing Sea, without the typical detrimental effects of a standard FEV infection.
Virgil created this unique FEV strain during his time at the Institute. When he decided to leave, burdened by the Institute’s actions, he injected himself with this virus as a means of escape. This transformation allowed him to survive in the harsh environment, hiding from the Institute’s pursuit. However, over time, the Super Mutant form began to take its toll, leading him to seek a way to reverse the process. Hence, he tasked the Sole Survivor with finding the serum he developed to counteract his specific FEV strain, located within the Institute’s FEV Lab.
The serum’s functionality hinges on its ability to precisely target and neutralize the effects of Virgil’s modified FEV. Unlike a general cure for all FEV strains, this serum is tailored to his specific mutation. This specificity is crucial because a broader-spectrum FEV cure could potentially cause unpredictable and harmful mutations in individuals already adapted to the wasteland environment. By providing the serum to Virgil and waiting a few in-game days, the player witnesses the complete reversal of his transformation, restoring him to his human form.
This event grants the player access to Virgil’s lab and all the items inside. It also influences Virgil’s disposition towards the player; if the player destroys the institute without finding the cure, he will become hostile upon their next encounter.
Frequently Asked Questions (FAQs)
What happens if I don’t give Virgil the serum?
If you choose not to give Virgil the serum, he remains a Super Mutant. The third entry on Virgil’s terminal suggests that he is losing his memory and sanity due to the mutation. Furthermore, if you destroy the Institute before giving him the serum, he will become hostile and attack you on sight, removing the possibility of obtaining his help or using his lab.
How long does it take for Virgil’s serum to work?
After giving the serum to Virgil, you need to wait approximately three in-game days before returning to his cave. Upon your return, you will find that he has transformed back into his human form.
What happens if I side with the Institute?
Even if you side with the Institute and become its director, there is no dialogue option to convince the now-human Virgil to return. While you can give him the serum and cure him, he will remain outside the Institute, preferring his independence. His terminal entries suggest the mutation was affecting his sanity; this, coupled with the Institute’s unethical actions, likely contribute to his desire to remain apart.
Can I give Virgil’s serum to Strong?
No, you cannot give Virgil’s serum to Strong. Strong, another Super Mutant companion, expresses a preference for his current form and dislikes the idea of being “cured.” Attempting to give him the serum will likely result in disapproval and a negative impact on your relationship with him.
What do I get for killing Virgil?
If you choose to kill Virgil, you can obtain Virgil’s Rifle, a unique energy weapon. This weapon can also be obtained by pickpocketing him with the Pickpocket perk Rank 3 if you choose to let him live. Additionally, if you are a member of the Brotherhood of Steel, killing Virgil can fulfill a quest for Elder Maxson, rewarding you with a piece of Power Armor.
What happens if I tell Virgil I can’t find the serum?
You can attempt to lie to Virgil about finding the serum through a series of three speech checks. Each check increases in difficulty. Successfully lying will initially prevent you from giving him the serum. However, you can still initiate dialogue again and choose to give it to him, essentially overriding the lie.
Can Virgil be killed?
Yes, Virgil can be killed. However, killing him before obtaining the serum will make it unobtainable if you have not yet found the serum and made it back to him to deliver it. If he becomes hostile (usually due to destroying the Institute), you will have no choice but to kill him.
What happens if I bring X6-88 to Virgil?
Interestingly, bringing X6-88, a Courser who was previously ordered to kill Virgil, has no effect on their interaction. Virgil doesn’t acknowledge X6-88’s presence or past actions, highlighting the limitations of companion interactions in the game. However, if you allow X6-88 to kill Virgil, he will dislike it.
Why does Virgil become hostile?
Virgil will become hostile if you are considered an enemy of the Institute (typically after siding with another faction and undertaking actions against the Institute) or if you destroy any of his defenses near his cave. These actions trigger his protective instincts, causing him to attack.
Is it worth joining the Institute?
Whether joining the Institute is “worth it” depends on your play style and desired ending. Joining the Institute offers access to unique technology, including energy weapons and synth companions. However, siding with the Institute means supporting their often morally questionable actions, which may conflict with certain players’ ethical choices. To understand more about this, explore GamesLearningSociety.org to see how game narratives impact player decision-making.
Can I betray the Institute after joining?
Yes, you can betray the Institute by acting as a mole for the Minutemen or the Railroad. This involves undertaking the “Underground Undercover” quest for the Railroad, which allows you to undermine the Institute from within while appearing to be loyal.
Can I spare Virgil?
Yes, you can spare Virgil’s life. Sparing him is the ideal choice if you want to complete his quest and gain access to his lab. If you are aligned with the Brotherhood of Steel, you will need to ignore the quest that they give you to hunt him down.
How do I prevent Virgil from becoming hostile?
To prevent Virgil from becoming hostile, avoid destroying Institute property or becoming an enemy of the Institute. Also, there have been some glitches reported in the game that can cause him to act hostile, though these glitches are not common.
Is the Sole Survivor a synth?
The game strongly implies that the Sole Survivor is not a synth. The game states that they were cryogenically frozen and thawed in Vault 111, making it impossible for them to have been replaced by a synth.
Does Sturges know he’s a synth?
The game does not explicitly confirm that Sturges is a synth. While there are theories and speculation within the player community based on hidden developer content, there is no in-game evidence or dialogue that confirms this. He’s probably a Gen 3 synth and does not realize it, like Danse.
Conclusion
Virgil’s serum is a crucial element in Fallout 4, offering a unique opportunity to reverse the effects of a modified FEV and gain access to valuable resources. Understanding the intricacies of the serum, its effects, and the implications of your choices regarding Virgil is essential for a complete and satisfying Fallout 4 experience. Whether you choose to cure him, exploit him, or even eliminate him, Virgil and his serum offer a compelling narrative thread that adds depth and complexity to the game’s world.
