Vermouth: But if Sherry's going to be on the train, then wouldn't that be the perfect hunting ground?
Gin: Yeah... if we could stop her getting off somewhere then she'd be as good as trapped in a steel cage. If we can flush her out through fear, like in deer-hunting, then she'll simply present herself to our guns.
Vermouth: You know why I leaked this information to you, don't you?
Gin: You're telling us not to lay a hand on the steel serpent before it returns to its den, am I right? Ah well, I'm pleased to hear you mention Sherry. I was beginning to wonder if you were harboring some strange sympathy for a fellow woman.
Vermouth: Don't be silly. Who do you think I am?
Next scene...
Ayumi : Oh wow! This is the first time I've ever seen a steam engine.
Genta : Me too!
Mitsu : It's spectacular!
Ai : It's only a steam locomotive in its appearance. Inside it's (can't see the kanji, resolution's too poor...maybe maglev powered by diesel?)...(coughs)
Ayumi : Your cold's still not getting any better?
Ai: It seems as though as certain somebody's strain was particularly persistent.
Sonoko : Usually this train only runs once a year, but Uncle Jirokichi announced that he'd be running it specially next month with some jewel on display in the first class carriage. That's why I'm getting on board early this time - I'm planning to leave a letter, fiilled with passion and love, tucked away in the carriage. What do you think?
Ran : I don't think Kid would have the time to find the letter. Anyway, Kyogoku-san would get really cross with you, you know.
Sonoko : My love for Kid goes in a separate stomach.
Sera: As for me, I'm more interested in the mystery quiz that occurs on board!
Ran : Sera-san!
Sonoko : Why are you here?
Sera: I'm a detective, it's only natural that I'm boarding. Isn't your dad with you?
Ran : He was here a moment ago...
Man being shot (I think): Don't come in!
Genta : Wow! It's just like the real thing!
Mitsuhiko : Let's go after him!
Genta : Yeah!
Ayumi : Come on, Conan, Ai!
Ai : Rather than a mystery quiz...this is...
Conan : More like hide and seek?
And the last extra page (don't have time I'm afraid), the basic gist sounds as though Vermouth is justifying going after Ai, in that although she said to Conan that she wouldn't lay a finger on her, it's Bourbon going after Ai, so technically she's keeping her promise.
