"Kid, you're being way too modest."
Fujino quietly sized him up and said flatly, "From what I've observed, your mental age is at least sixteen or older, and your deductive ability is on par with a proper detective's. You occasionally put on the act of a child and do things fitting for someone your age, but you're nothing like a child."
"...?"
Conan silently put a question mark in his mind, inexplicably starting to panic.
A mental age of sixteen or older... wasn't that basically hinting that Kudo Shinichi was seventeen?
A proper detective... he really was a High School Detective, and a famous one in Japan at that.

For a moment, thoughts surged through Conan's mind. He temporarily put aside the matter of letting the murderer go and instead began wondering whether Fujino was hinting that he was Kudo Shinichi.
He was panicking like crazy.
Logically speaking, the odds of Fujino figuring out that he was Kudo Shinichi were not low.
In fact, Fujino had probably suspected it for a long time.
