Doorbell

A yellow sign reading "423 SHADYBROOK LANE" is shown above a doorway, then the scene cuts to a woman with purple hair and a man with orange hair standing on a city street at night, looking at a glowing device on the wall, as a tall robot with a grumpy expression joins them. The robot, the woman, and the man stand together on the street, looking at the device, while the camera cuts to a close-up of a screen displaying a grid of blue cubes.
