It turned out that Andre Camel wasn't a spy from the black organization. Furthermore, it seemed that Conan, Akai, Rena, Camel, and Eisuke all comfort each other just before the strategy meeting, and made up a plan to make Rena return back to the black organization in a way that looks like she was escaping from the FBI. We still don't know what happened exactly between Conan/Akai and Rena/Eisuke/Camel, and where Eisuke has gone.

However I like the idea that Eisuke is still hiding under Rena's bed.
