Alfonso had been traveling to areas that were specified in the task given by "that" person. The task was not particularly hard, as the foundation for this was laid years ago. He was just the person to execute the plan that had been in the making for years.
He never really met them for years on end. The major reason being the instructions from the person. The plans have finally reached fruition, and now he was left with a final job. The job entrusted to him was to inform the members of the final task and when to proceed with the job.
Alfonso's job was simple. He had to collect information and communicate with the members, ensuring that the plan would proceed smoothly. He couldn't betray in this situation either, since his mom would definitely be under their surveillance if the plan was successful.
