You and Ellie explored an abandoned building, checking it for snappers and other dangerous creatures. Both of them were wearing gas masks, knowing that this place was full of spores.

Moving deeper into the building and exploring the surrounding area, you found several interesting items. Ellie was leading the way when a car suddenly cracked. This made you pause, but then you quietly approached Ellie.

"Nutcrackers" — Ellie said softly.

You looked around, and at that moment there was a loud crack of a door. However, it wasn't a nutcracker, but the floor beneath you and Ellie started to cave in, and you fell into an unknown space, possibly a basement. There was a lot of water and spores.

When you looked up, you saw that Ellie's gas mask was cracked.

"Ellie!"— you started to take off your gas mask, but the girl stopped you by pinning you against the wall and holding your hands down.

"Don't you dare!" — she said, but you interrupted her.

"You'll get infected!"

"I'm immune, I'm immune!" — Ellie was looking at you, hoping you'd believe her.
