They are talking about the plague
Edward: We must be fast! We have no time to get testing approval. I want to try this by myself.
Nadezhda: Are there any other ways?
Edward: no, if I survive, we will succeed. If I die, we are close to it.
[Edward is going to drink the untested medicine, but Nadezhda take the medicine before him]
[Edward is shocked]
Nadezhda [smile]: I trust your knowledge.
Nadezhda: If I die, don’t call an ambulance. You know how fast it is. Just record the death process.
Nadezhda starts feeling bad. She knows she is going to die. She took off her uniform and showed her beautiful clothes behind it.
Nadezhda [talk to Edward]: Am I beautiful?
Edward: Yes… Are you ok?
Nadezhda: You failed…
[Nadezhda start feel pain in her stomach]

Nadezhda [smile]: I know you like me, you just don't dare to say.
Nadezhda [shy]: After I die, my corpse is just dead meat. I will feel nothing. I won’t be angry if you do anything to me…
Edward [sad]: No… no…
Nadezhda starts to struggle on the ground. Edward tries to hug her.
The face and other skin of Nadezhda is fully sweated.
Nadezhda’s eyes are looking straight forward.
Blood starts coming out from Nadezhda’s mouth and nose.
The struggle becomes very strong. Including “opisthotonos”
Nadezhda’s struggle becomes weaker and weaker…
She has a very rapid and small extent struggle with a long interval.
At last, Nadezhda becomes very weak and only head can move. Her pussy and ass were soaking wet and her hair was soaked with sweat
Nadezhda[weak]: please clean my body…
Nadezhda is dead.
Her eyes are half open.
Her mouth is also half open.

For the eyes, don’t let the eyes become fully white.
When she turns her head, her eyes should follow it. The pupil should always be in the center (living people tend to turn their eyes before they turn their head. However, we need to avoid this here).
Edward uses a towel to clean Nadezhda’s face.

Then, he took off Nadezhda’s clothes. Nadezhda’s body is also fully sweated. So he used a towel to clean it.
Nadezhda’s body is still very soft since she was just dead for minutes.
Edward uses a white cloth to cover Nadezhda’s body and starts crying on her body.

He is so sad and tired. He fell asleep on her body…
After a night, Edward weakup.

He noticed that Nadezhda had been dead for 12 hours.
[note that Nadezhda’s eyes are still half open]
Edward tried to put Nadezhda’s clothes back on her body, but he found her body was so stiff that cannot move at all.

To show this, Edward first tried to move her arm, and Nadezhda’s arm just moved a little bit.

Then, Edward tries to turn Nadezhda’s body, and her body is turning as a solid body (compared to soft people, their legs, arms will move during the process). See reference.

On her back, the area that is not touching ground (back neck, waist) showing dark red color (post-mortem lividity), see reference.
Edward gave up and waited for her body to become soft…
After two days, Nadezhda’s body starts to rot and become soft.

Due to the rot reactions, her body became sweaty again.

But Edward cannot clean such a body. Luckly, Nadezhda’s body is very soft now. He can put clothes back on her body now.
