File 891+

interessantissima teoria sulla vera identità di Amuro http://forums.dctp.ws/viewtopic.php?f=5&t=...=808106#p808106

in effetti con quella frase sull'appendice di Amuro, Conan sembra aver capito chi sia... se fosse una frase normale la sua reazione mi sembra eccessiva... quindi deve aver intuito qualcosa... quindi Amuro è BUONO!

Our translation distinguishes between two ways to say 0: Zero (ゼロ) and Rei (零).
What does that mean? Every time you read 'zero' in a DCTP release (ch. 888+) it actually says 'zero' (ゼロ) in the Japanese file, not 'rei' (零)! Only Elena says 'rei' and thus our translation also says 'rei'. I hope that makes things clear!

Now, as to the matter of Amuro belonging to the Public Security Bureau or the Security police (I think the latter makes more sense, because of the 'Zero' thing) ...
After noticing Amuro's reaction to the word 'zero' and his appendix comment, Conan probably thinks Amuro is part of the SP, however, in reality Amuro likely got the nickname 'zero' (0) because his name, 'Rei' means 0, so Conan is making a mistake here...
This actually makes sense if you look at file 892, where Conan apparently* asks Amuro whether he's an enemy of the bad guys and Amuro tells him that he's wrong. (p. 15/16)
So we have file 888, where after the 'zero' and 'appendix' (盲腸) comments, Conan suddenly thinks that Amuro might, in fact, be part of the Security Police, then in file 890, he calls Amuro 'Zero-niiichan' with his 'I've figured it out' face and in file 892 he subtly asks Amuro for confirmation: 'You're an enemy, right? ... Of the bad guys ...' And Amuro corrects him, saying that he misunderstood -> cue Conan's scary face, as he realizes that Amuro is, in fact, a bad guy.

* I've not actually seen the Japanese file yet, but two people who know Chinese have confirmed that that's what Conan says in the Chinese file.
