Percival approaches Daniel and John, and calls Lucien.

“Daniel? Have your been unplugging the fans in the Tower?”

Daniel: "No, why would I do that? All I've done is dump flour all over the floor after the guy said the fans were unplugged, we need to get more flour ...and get some fly paper, like a lot of fly paper."

Percival looks at Daniel and starts to get huffy then just shrugs and nods, “you’re suspecting that someone’s in the house still?”
