Ayumi: Ai-chan...I think I'm going to have to kill you before I'm able to have Conan-kun for myself. I'm sorry it has to be this way.
Ai and Conan: Wh-Wha!?

Mitsuhiko: Hey, Conan and Haibara! You never told us you were in a band with that famous high school detective and a really pretty woman!
Ayumi: Yeah! That looks SOOO cool!
Genta: We're totally getting free backstage passes now, right?
Conan: (thinking) THE...THE HELL? HOW IS THERE A BILLBOARD FOR A BAND THAT CONSISTS OF ONLY TECHNICALLY TWO PEOPLE? ...WHO AREN'T IN A BAND?
Ai: (thinking): My god... Did they really make me wear that dress? That color is definitely not flattering.
