You check the weather report while recovering from your adventures in wrongdoing, but there is no mention of fog. That doesn't necessarily mean there won't be any, though. Often it just comes, unannounced and out of nowhere.
Instead of fog, you are greeted by two beautiful, sunny days. That's probably a good thing, since it seems not everybody has finished doing their duty of making themselves targets for the fog. While your friends carry on with that, you spend these sunny days preparing for your little paranormal test.
