Noon the next day.
Watson had been preparing for the day to infiltrate the elves. He first asked Delta about their language and then their etiquettes and living habits. He hid in his room the entire night.
"When you meet the elves, you have to greet them with honorifics. However, you don't have to lower your head when facing an older elf. Instead, you have to stomp your feet. Facing an older elf of a different tier requires you to stomp your feet a different number of times. That is different from humans."
Standing in front of a huge bronze mirror, Watson wore a suit made of leaves that fit him. He looked at it over and over again. At that moment, his hair had changed from the previous golden color to a light green color. He also had pointed ears.
Those changes were due to his ever-changing magic. Even with his transformation into an elf, coupled with his learned speech skills and manners, no elf would see through his disguise.
