As Lost fever grips the nation, there's a sinking feeling among fans that it's almost over. Ditto goes for the ensemble cast, a relative group of unknowns who have become some of the business' biggest stars. Actress Yunjim Kim, who plays Sun on the ABC hit, feels it too.

In person, Kim isn't really at all like Sun, who we've seen in two flavors: as a sheltered wife of a dominating Asian man and a down-to-business, driven woman who will stop at nothing to achieve her goal. In real life, Kim falls somewhere in between: confident yet graciously accommodating. Over a fancy juice concoction (her) and a beer (me), we chatted about Sun's origins and what little Kim can say about Season 6.

TV.com: It's the final season. What's the mood like on set?

Yunjin Kim: Right now, we're just trying to finish the day. I'm very involved in this particular episode we're working on right now [editor's note: they were filming episode 13]. All of us, the crew the cast, we come to work and try to do the best we can under the circumstances we have, go home, get some rest, and do it all over again the next day.

Do you think that the fact the show is ending is going to hit you all at once?

It'll probably start around two weeks to [the end of shooting]. We're all going to have separate end dates for actors, we'll probably have a big party afterward, but on that day, when it's "Martini Time" for Yunjin forever, I'll be bawling. It better be an emotional scene, because I'm going to keep on crying.

One of the things I love about Lost is the diversity of the cast.

It means everything to me. I know when I was growing up in New York, whenever I turned on the television, I never saw a face that looked like me. Whenever there was an Asian person on television, it would be a huge event, me calling to my older sister "There's an Asian person on television!" It was unheard of back then. Now, after Lost, it just happened with all these other shows—Grey's Anatomy, FlashForward, Heroes. It's not unusual to see an Asian American on television anymore. That was never the case before Lost. I'm not saying Lost made it happen, but timing-wise, it was Lost in 2004, then Grey's Anatomy in 2005. We're looking at a different blend of what America wants to see and accepting what America is all about. Diversity.
