(For more 'updated' details, check previous "Bourbon" entries)
Bourbon solves a code Conan makes when the detective league is trapped and he comes to save them but hides the fact that he found the code and says he just happened to be passing by. He also finds out where Agasa's house is. (It's at this point he must learn about Agasa's gadgets and what Shuichi used in faking his death)
Bourbon and Vermouth are in disguise and hear Jodie talking about the case at the hospital and Shuichi touching the phone. This gives Bourbon more information on the case, to piece things together.
Conan runs into Bourbon in the hospital (the hospital where Rena was being held) and says he's looking for a friend "Kusuda Rikumichi". This is the guy who was posing as a regular patient but was really working with the black organization. Bourbon asks if Conan knows him. Conan immediately says no, and Bourbon says that's amazing because most people don't instantly know that they don't know someone just from the name, and they might ask more questions. Bourbon has basically figured everything out at this point but needs to confirm it. So he creates a scheme to get Camel to tell him what he needs to know.
Bourbon asks Takagi about Rikumichi. Takagi tells him that a few days before the bombing case (Rena's case) that a damaged car was found not far from the hospital, and that the owner was Rikumichi. And that there were blood splatters in the car, which seem to have been caused by a gun.
It's with that, that Bourbon completely figures it out.
It's during this case that Akai confirms Bourbon's true identity officially, and Conan finds out who Bourbon is really working for. Bourbon knows Akai is still alive but doesn't know where since Conan set up a trick to throw the trail off Subaru. Akai continues to live at Kudo's house as Subaru, in order to keep an eye on Haibara.
Conan and Bourbon seem to be on good terms at the end of the case, since Bourbon is also an enemy of the black orginization. But Bourbon still doesn't know Conan is Kudo.
Before getting cut off by Vermouth, who still thinks Bourbon is with the black organization, he starts to say her secret, that she is the boss's...
Also, in a text to Shuichi from Rena, we learn the code name of someone higher up than Gin (The head boss' number 2), that is "Rum". And we also learn that the Boss has started making movements.
