Hoowee what a doozy... The comments below summarise Ji-tae's situation much better than I could, so I won't bother.
This new character, Red Head tho, is starting to look like a very VERY hate-able gal. Which is not bad, total prick villains are good too. It'd just be nice if she wasn't entirely hate-able like the judo bully was before, although we haven't really seen her story at all right now. That being said, I get the feeling she won't be the Big Bad of this arc for some reason, or at least she won't fight Jiu Ji-tae. But I could be very wrong.
P.S. I wonder why Bob Sopp feels like he doesn't belong... maybe he's got some history al a tunnel
Edit: Red head is a woman also I called her Red hair, thanks
