Ruin Be Like:

If they stick with child player characters then the timeline is gonna go from "children die here" to "children get f*cking traumatized here by once-friendly characters here"
And honestly I love both

Those Kids Are Gonna Have Terrible Flashbacks 🤣

Given Cassie lives, doesn't end up being the next Vanny (or at least recovers from that), and also has her own kids one day, the kids are gonna ask if they can go to Freddy Fazbear's Pizza and she will tell them the whole of Ruin. Two things could happen from that point:
A. Kid doesn't believe them and the cycle repeats
B. They never want to go inside the building

I Think It Will Be A.

Yeah
