All of a sudden, Enrique felt a sharp twinge in his forehead. He brought his hand to his head, stopped walking and looked around, suddenly afraid. Jeff and Carol noticed and came toward him. Emma also shared their concern, and was about to come to Enrique's aid; but something gripped her, paralyzing her: a familiar signal that came from an artifact that she hid within her clothes.

"Is something wrong? Did you leave something behind?" asked Carol. Emma thought for a moment that Carol was talking to her, which lifted her spirits for a split second.

"We can go back," Jeff said as he approached Ortega, who was rubbing his forehead with a gesture of frustration.

"No, no," Enrique answered, "I'm fine. It's just stress with the exams, that's all."

"I have to go," said Emma, surprising everyone. "I just remembered I . . . have a meeting . . . with my family . . . about the family business . . . bye!"

Emma was often dashing off without warning, so nobody was surprised by her sudden change of plans. She took off at a quick pace, disappearing into the dim light of the lantern-lit crowd. 

Meanwhile, Enrique knew that the twinges he was feeling could mean only one thing: he would soon be having another of his recurring visions.
