The Ask Your Mom quest in Quarantine Zone: The Last Check should be simple to complete, but it’s pretty easy to get confused.
This task doesn’t involve finding any undead. Instead, you’ll be tasked with figuring out the source of six graffiti poems that can be found all around your base. This guide will provide you with locations for all six graffiti if the in-game clues aren’t handy enough.

How to start the Ask Your Mom quest in Quarantine Zone: The Last Check
The first job is to start Day 8 and unlock the Bulletin Board (happens on Day 7). The first graffiti will appear right in front of your tent where you sleep. From there on, you’ll have to find five more graffiti.
Graffiti 1

The easiest one to find. Located right outside your tent, use the flashlight if too dark. Once you spot the first graffiti, a pair of footsteps will appear. Your next task is to follow the footsteps. You’ll have to visit the remaining graffiti in the same order as shown by the footsteps.
Graffiti 2

The second one can be found in Storage. Go straight, turn left, and you’ll find the message on the wall by the blue potty.
Graffiti 3

The third one is found in the lab area. Instead of going inside the lab, go right. You’ll find a large white-colored generator, with the message splashed on it.
Graffiti 4

Go back to your tent, and you’ll find the fourth one on the outer wall of the container where you sleep at night.
Graffiti 5

The fifth one is found in the Liquidation area. Enter through the gate, go on top of the green tower on your left, and you’ll find the writings.
Graffiti 6

The sixth and final one is outside your tent area. Find the spot where Laboratory is written on the wall, and you’ll find the final graffiti over there.
Once you’ve found all six graffiti, go and speak to Abe Crow in the storage area (who wears a hazmat suit). He will ask you to find the culprit. Go to the Survivor’s Block, and you’ll find a person with paint on his clothes. Speak with him to complete the quest. You can receive money from completing the quest, or choose not to take it from the tent.
