I Love Ai

I just had an idea that Subaru Okiya might be Yusaku Kudou in disguise but I think it is more fitted that Subaru might be Shuichi Akai since we remember from previous episode that Haibara's sensed that Subaru is with the Black Organization. He might be Shuichi because he was [pretending to be] a part of the BO.

what do you think is the most emotional scene in detective conan?

i watched episodes 279-280 (The Labyrinth's Hooligan) of Detective Conan. then at the end of episode 280 a theme song played and i liked it very much that i searched for the music for hours but i still can't find it. anyone knows what theme song played at the end of episode 280?
