To confused reviewers because of this line on chapter 20:
"May we please go somewhere before we go to your house Yoh? I would like to visit my parents. I haven't seen them in over eight years," Lyserg asked. Yoh nodded. "London, here we come," Lyserg said...
That means that he hasn't visited his parents graves in over eight years. I'm sorry if that kind of confused you. I should be more specific, shouldn't I?
