Conan, is the ultimate wingman for Takagi. I'm glad he let Takagi get his first kiss at last.
Anyway, good case with the superintendent getting some backstory and Takagi-Satou relationship being developed. I do wish the superintendent was one to take down the murderer to save Takagi but that's O.K because his original gruge is now dead.
The original serial killer was lucky he manged to get his message across. It's also funny that Megure dismissed the notion that a copycat killer murdered the victim when that was the meaning of the dying message in the first place!
