Yay! Ken Leung returns and finally shares some screen time with his Lost co-star Michael Emerson. When I first heard that Ken was joining the cast, I was under the impression that he would be a series regular. My guess is it will be more along the lines of what we get from Paige Turco when she occasionally pops up here and there. Very cool to see Julian Sands make an appearance. Since he didn't get whacked, my guess is he will have more episodes in the future. They set up at least one more episode for sure. Anything beyond that is a wait and see proposition.
