For Fang Zheng and Conan, the Rokuhara Island incident has many doubts that are yet to be resolved.
The first doubt is whether Beatrice really exists.
The current evidence suggests... this person likely exists.
Because indeed there is an annex on Rokuhara Island, but Conan also said it looks like no one has lived there for over ten years.
So taking that into consideration, it means ten years ago, someone was living in that annex.
The question then is, who lived in that annex at that time?
And the second doubt is... Sayaka Yasuda.
This person on the list, Fang Zheng has never met.
However, Conan has given an answer this time.
"I asked Mr. Renji, he said Sayaka's real name is Sayo, and Sayo was her name when she worked as a servant."
"So then, is Sayaka Yasuda actually Sayo?"
Upon hearing this, Fang Zheng squinted his eyes and began to think.
"Then who is Kanon?"
"Mr. Renji said Kanon is Sayo's younger brother... "
