Take me down the list of some of the friends you’ve made in this cast.

"What’s interesting in working on Lost is that you don’t work with everyone together. Hardly ever. Last season, I had a lot to do with Dominic Monaghan, who… "

Who’s gone back and won’t be on the show?

"Well, maybe. We’ll see."

You’re right. Why am I assuming anything?

"So I worked very closely with him. Our storylines had him going in a very dark place. I thought he did a fantastic job in the season finale, working with him on the boat, when he was doing his final scenes on the kayak."

"It sent shivers up my spine. It was just very moving. He’s a really tremendous actor."

I can't even ask whether you’ll miss him or not.

"I know. I’m guarding everything I say in case I give anything away. You always think, 'Can I say that? Can I say that?'"
