So who is Scar/Fake Akai?
Answer: Hattori Heiji
Why?:
First: Because he's always wearing a cap.
Second: He can't talk because he has a different accent. So it will be noticeable.
Third: Figure. His overall feature looks the same as Shinichi & Heiji.
Reason: He pretty much needs to get involve in the BO situation one way or another.
Well about the scar and the mask, I guess Heiji asked Yukiko's help without Conan's knowledge. It's possible because they've already done it before in EP 345. (But with Conan's knowledge)
It's not a deep observation. Just merely a hunch. :p
