oh man, just got off watching ep.13.
Spoiler:
It looks like the only associate of Harry's who doesn't know what is really going on is Brandon!
I guess I wasn't paying attention at first and figured since brandon was cleaning up Harry's opponents full throttle this episode, he was therefore as conniving. But then I went back to the start of the episode where Harry duped Brandon into thinking the firearms smuggling was headed by a family member. Of course Brandon didn't realize that Harry, along with Kugashira Bunji, and the rest had already found a guy to pin this on,--Randy.
EDIT: Thx Mr.Minou. spoiler markups now included.
