The Fifth Mole?
Okay, I just finished watching IA3 and for the life of me can't figure out who the 5th mole was.
In IA3 approximately 15 mins into the movie we are revealed by Inspector B that there are 5 moles
1) Inspector B himself
2) Ming
3) Chun (the guy that Yeung got to kill himself)
4) and Yeung himself right?
But who is the 5th?
Or when Ming asked how many more moles was they, did he literally mean how many MORE? In which case, the answer excluding Inspector B but including Ming would mean there are 4 other moles. If we account for Chun and Yeung, that means there are 2 other moles we don't know about.
Can anyone clarify this (and to those with cantonese ears too) or is my maths just terrible?
