that's an excellent question, nowhereman. to address this, let's review some of the earlier posts in this conversation, and see if we can find answers within:
there are 5 "J" names associated with some main male characters on the show
now you'll notice i mentioned key, defining words like "some" as well as "male" in an effort to lighten the load on the theory.
now, if you'd like to include some slightly lesser characters like jin, or maybe female characters whose names start with a letter really close to J in the alphabet, like kate, then we can evolve into a new theory that you and i share with one another. we'll always have this theory together, just the two of us!!!
