I'm still amazed that such an early chapter is the basis for the story of two of the most important characters of the series, both introduced more than a hundred chapters later. Aoyama is great!
I'm not sure whether to be impressed or disgusted by how Gosho basically took 150++ to continues the consequences(Haibara Ai) of this chapter. It basically more than 3 years before he continues the story regarding Akemi death.
