Despite the whole town believing it to be an angel, Lisa takes a sample of the skeleton and has it tested to see if it is one of a human. The results are inconclusive, leaving Lisa still skeptical. After an interview about her beliefs, there is a town riot against the science community. During the riots, the skeleton is stolen. The town finally discovers it on a hillside with the message, "The End Will Come at Sundown" carved into it. However, the entire ordeal turns out to be publicity stunt that was pulled off by the mall's developers. Surprisingly, the town is not angry, but is instead fascinated by the low prices at the mall.
