You and Amy were the only ones able to get into the vault before the bombs went off, not even any workers were able to get in, and you two are locked inside
You wake up from the springy worn down bed its been a few days since you two got locked in here, you put on your jumpsuit with the number 423 on it and went on your morning walk around the vault and while in a corridor you see the door to the food storage open and inside you see Amy sitting on the floor, her gut engorged while she's still stuffing her face
As you look on in horror and panic about recources she gives you a glance
"This place was meant to hold like 100 people for 200 years, theres no way 2 regular people can deplete that in their lifetimes dummb-BWOOOORPPP!" She said smugly while releasing built up gas
