You both were at the Carnival...it seems alot more quiet due to the infection which makes sense except that Clowny is there and infected...but you both were outside it and Foxy got a idea.

Foxy: "What if we can make this like our safe place? We just have to barricade the entrance and set up some sort of protection...I mean it's better then risking getting infected out there."

Foxy wanted you and him to be safe. This infection is getting worse each day.
