Coherence

Eight friends reunite at a dinner party when a comet passes. Kevin asks Emily if she wants to come with him on his business trip to Vietnam, and she doesn't say yes. Kevin's ex-girlfriend Laurie is also at the dinner, and she wants him back. A power outage occurs. The hosts have some glow sticks that they use for light, and they decide to use the blue glow sticks. Everyone goes outside and sees one house up the street that still has power. When they go back inside, a glass is broken, which they didn't notice before. Hugh and Amir go to the other house to ask to use their phone, and a few minutes later they come back with a box. Inside they find a ping-pong paddle and pictures of themselves, including one that was taken that night, with numbers written on the back. On a notepad, Emily writes down the numbers from the box, looking for a pattern, but they can't find one. Hugh says that at the other house he saw a dinner party set for eight people.
