He said to the miniature microphone, "I'm going to swap his hair now."
The "he" was, of course, referring to Alex Duncan.
At that moment, a waiter had already approached Duncan, who was hiding his identity. He successfully cut off his hair and turned to leave.
"If I fail, it will be up to you guys," Finn said.
With that, he leaned over again.
It was the same trick, but this time, he moved slightly closer to the waiter.
The waiter frowned and was about to leave him in the next second.
However, Finn did not let go of him. Instead, he deliberately rubbed against the waiter's body for a while.
The moment the waiter noticed something strange and was about to make a move, Finn turned around and left.
That was because he had succeeded.
He walked a little faster and said as he walked, "Done."
