At first I had a problem with Shioon fighting someone again that was leagues ahead of him, especially when he needs to take pills just to fight. If the SUC guy didn't have a broken leg, none of this would have been interesting.
Kwon should serve a purpose in any case… either make a decision and choose not to kill Shioon right now, or get involved and attempt to kill Shioon himself. It would be pointless for Kwon to be there just to see Shioon get saved by someone else, and we all know Shioon won't be dying.
Sounds like a good scenario for So-Chun to stop by and say hi, and stop Kwon from proceeding to kill Shioon.
