I loved seeing Keamy this episode- totally unexpected! Also, the bald guy was on the freighter. His name is "Omar" according to lostpedia.
I knew I had seen him...thanks DMM!!
Once we saw Omar get out of the SUV, we recognized him right away, and knew that he was taking Sayid to see Keamy. So we weren't really surprised when we first saw Keamy's face.
Oh, you're good! I knew we had seen him before but somehow I had it in my head that he was the guy who had tortured Sayid in Paris in retaliation for his wife's torture during the war. But I'm glad I was wrong. I love it when a reveal is really a surprise for me.
It definitely looks like Jin was in LA to see Keamy and things went horribly awry. But I think this is a difference in this reality. I'm not convinced Keamy was the person with whom Jin was meeting in the original timeline. And I have a gut instinct that while Keamy is obviously a higher up in this "organization" he isn't the Big Boss.
Wasn't locked up with Keamy but by Keamy. Still does not tell us why. Is Mr. Paik doing business with Keamy, was Jin doing something on his own with Keamy? Was the money Jin's or was he surprised by the money??
So many unkonwns.
Remind me again what a watch had to do with Jin? Wasn't he supposed to deliver a watch too or was that just a ruse? Too much to remember. 
Yes, he was supposed to deliver a very nice watch to someone with whom Mr. Paik does business. It was some sort of message that only big, evil, rich guys understand. It was apparently such an important job that Jin completely freaked out when he saw that Michael had the watch in the original timeline. But there was also an indication that Jin was planning to deliver the watch and then ask Sun to start their lives over again in America. So if the money is his that's what I think that was for. If it's not his... then we have another question. lol.
