The origins of Emily and Elpis

Rewind to 1990 at the Raccoon City orphanage  . A sleeping "Emily"  hears a commotion. The caregivers are distraught, unable to control "them." She enters a nearby room and sees a doctor surrounded by children. He shoots one of them in the head, but the wound heals quickly. The children's faces resemble  Emily's,  but their heads are shaved and they bear surgical scars. They coldly break the doctor's wrist.

Emily  was so terrified that she hid under the bed. The children, checking each bed, heard the screams and rushed out. At this point, the nursery staff, or more accurately, the doctors who had experimented on the children, were all killed. The children kept injuring themselves but still healed.  Emily later went to the conference room and learned that the children were just clones, raised in a laboratory to be "guinea pigs" for Umbrella  's research  . If they failed, they were simply destroyed, and  Emily  was no exception.

 He claims that scientists have been unable to replicate the formula, but now he has the "original" in his hands, which is the creation of the creature. At this moment,  Grace  is shocked to learn that she is a man-made creation, the reason her mother,  Alyssa,  was murdered, and the reason for the creation of the monsters she encounters in  the Rhodes Center .

The bizarre drugs used in the experiment transformed the children into monsters. For example, the monster constantly chased and tried to capture  Emily,  who it only intended to take back to its lair without harming her. It seemed all it wanted was to continue being Emily 's friend,   just like before the transformation.

As for Leon, she falls into a state of panic as she realizes so many terrible things are happening just because  Victor  and  Zeno  want to capture her. Zeno also appears and shoots at  him,  but he shows he's fast enough to dodge the bullets, similar to  Albert Wesker  when confronting  Chris Redfield . He summons an "old friend" of  Leon's , the Tyrant  bioweapon   that had been relentlessly pursuing  Leon  and  Claire  before. 

After a protracted battle,  Leon finally  defeated  Mr. X  once and for all. He then travels to an orphanage, home to grotesque mutated creatures like giant carnivorous flowers. This orphanage also holds a gateway to  Umbrella's secret base,  and Leon must now   confront a formidable enemy bearing a striking resemblance to the mysterious figure.

After defeating the enemy,  Leon  enters the central room where  Zeno  is trying to convince  Grace.  He claims that the technology to control human will already exist, but it's not capable of infecting many people, and he believes he has achieved this through [something].  Zeno  reveals that the organization is the one hiding  Elpis , keeping it in this secret laboratory awaiting Grace 's arrival  . However, a password is required to release  Elpis,  and if entered incorrectly,  ARK  will explode, completely destroying Oswell Spencer's "legacy. "

When  Leon  engaged in combat with  Zeno,  Zeno proved superior thanks to his super speed and regenerative abilities. Just as  Zeno  was about to finish  Leon off  ,  Grace  intervened, threatening suicide because she believed he still needed her. Taking advantage of this momentary lapse in concentration,  Leon  saved  Grace  , but he subsequently succumbed as his illness progressed to Stage 3. 

Leon  stated that he risked returning to  Raccoon City  because he wanted to make a difference, something he failed to do when he first arrived. Therefore, he wanted to destroy it, believing it shouldn't exist, and made  Grace  promise that if anything happened to him, she would be the one to destroy  Elpis .

With the help of others, she found her way to the central information room, where all the details related to her were stored on a floppy disk. At that moment,  Grace  remembered the disk her mother had tried to hide at all costs. She inserted the disk into the computer and discovered the truth. 

While she was alive,  Alyssa  approached  Spencer  as a reporter. He had locked himself in a room, a stark contrast to his previous behavior.  Alyssa  asked  Spencer if  he thought his actions had led to this outcome, and what he wanted the world to know.

 He asserted that what needed to be known was true, that his research had opened  Pandora's box,  leading to disaster for the whole world. He argued that humans cannot predict when they will die, so they have hope. At the same time, happiness cannot be achieved by harming others.

The video cuts to a scene where an assistant brings  Spencer  a baby girl, and he reveals that she is simply a lonely child he adopted as an act of atonement. He names her, which can be understood as "Grace," seeing her as Spencer 's apology to those who died as a result of the research   conducted  by the Umbrella Corporation.

Oswell Spencer's Requiem

Grace  then saw on the screen  that Leon  was collapsing outside due to the virus's effects. She found him and led him to where  Elpis was located , telling  Zeno that  she would only enter the password if he   spared  Leon . At this point, Grace  remembered what  Spencer, Alissa  , and  Leon  had said. This led her to two choices: release Elpis or destroy it.

Depending on Grace's  choice, the game will have two different endings. If she chooses destruction,  Grace  will enter the password  "Destruction,"  and the system will shut down, causing the entire area to be annihilated. Zeno  angrily grabs  Grace,  but  Leon  uses all his strength to slash him in the shoulder, allowing  Grace  to escape, while he himself stays behind to hold off the villain.

Although he couldn't defeat  Zeno, Leon  was still happy that he had saved Elpis. After leaving,  Grace  was picked up by a helicopter, and she wished she could have saved  Leon . In the other ending,  Grace  possessed  Elpis and  he was freed from the container.  Leon  didn't understand why  Grace  did this, and she explained that she wanted to atone for her mistakes. 

Zeno  , however, didn't care about that. He quickly grabbed a vial and injected it into himself, believing it to be a mind-controlling biological weapon.  Zeno  was actually working for a mysterious organization with a global control network. Their goal was to collect biological weapons for their own use, and  Umbrella  was also among their targets.

Unfortunately,   the revelation that Spencer was actually an Anti-Virus drug, capable of eradicating all the viruses the  Umbrella Corporation  had developed,  poured "cold water" on Zeno . This caused Zeno  to lose his superpowers. At this moment,  Victor  appeared, expressing admiration for Spencer's intelligence  . 

He believed that Elpis 's ability to neutralize biological weapons   would make it a powerful tool for anyone who possessed it.  Zeno  was enraged and said that both  Spencer  and  Victor  were merely tools for  The Connections  to exploit. Ultimately, he was  dealt with by Victor , who  then   stabbed  Grace in the stomach  after achieving his goal.

Victor  takes a vial and enters the password to destroy everything, then confronts  Leon . Although defeated, he then transforms himself into a monstrous creature, almost like  Nemesis  in  Resident Evil 3.  Of course, that didn't stop  Leon  from defeating him. After dealing  with Victor, Leon  finds  Grace , and the two are trapped with no way out. When all hope is lost, a group of  BSAA soldiers  suddenly appear and say that there is a message for  Leon  from Captain Redfield .

Finally, it all came to an end, and  Leon  said he had sent a dose of  Elpis  to  Sherry  to cure her illness.  Grace  , though freed, felt sad that she couldn't save  Emily.  However,  Leon  said he hadn't shot in vital areas, so it was highly possible that the girl was still alive. As  Leon  turned away, he took something from his pocket and put it on his finger. It appeared to be a ring, implying that he was engaged.

At the end of the game,  Grace  is on the phone with  Leon  about  Sherry  and  Emily,  mentioning that the little girl's condition is improving. She also says she's teaching  Emily  to read, and on the table is a photo showing that  Emily  has been cured of her cataracts thanks to  Elpis  and can now see the light.

It also marked the end of a "requiem" that  Oswell Spencer  dedicated to the lives he had stolen. It also offered hope to those who remained, like  Grace, Emily  , and even  Rosemary  , to continue their journey in the face of another equally dangerous enemy: the Organization  .
