Unless you’ve been lost down a hatch lately, you know that Tuesday marks the long-awaited premiere of the sixth and final season of Lost. The questions abound: Did Jack’s scheme to nuke the castaways back into a pre-crash reality work? Who is the mysterious Man in Black we met last May in the fifth season finale? What is the Smoke Monster? Will Kate pick Jack, Sawyer or none of the above? And what’s up with the freakin’ polar bears?! On Thursday when I talked with Emilie de Ravin, who plays the mysteriously disappeared island mom Claire, she unfortunately didn’t have that many answers for me. (Who knows, Dharma Initiative peeps may have been skulking around her side of the phone line.) But what did she spill? Read below to find out.

De Ravin is back as a Lost series regular in the series’ final season, after spending last year off as part of a holding deal. (The actress kept busy, though, starring with Twilight’s Robert Pattinson in the romantic drama Remember Me, in theaters next month.) When we last saw Claire, she was seen in Jacob’s cabin with her biological dad — and also appeared in a dream where she told Kate (Evangeline Lily) not to bring Claire’s son Aaron back to the island. So how we will see Claire in tomorrow’s premiere? “Mmmm. Yeah. That’s really hard to answer,” de Ravin says, laughing at my obvious fishing for scoopage. “You see her a couple different ways, actually. It’s been a lot of fun playing the old Claire, but I’m also playing with a new side of her.”

Of course, old-school Lost fans have seen Claire played a few different ways, from flashback Claire back in Australia, to getting-ready-to-birth Claire and her relationship with Charlie (Dominic Monaghan, who’s back in a few eps this season, too), to the cryptic character we saw last. Then again, most of Lost’s characters have had their multitude of different facets. “That’s one of the beauties of this show,” de Ravin says. “I don’t think I would be so excited about going to work on something where I’m just playing a day-in, day-out character for six years. A lot of actors are constantly challenged in doing something different and new, and you’re the same character on the show but you’re not really. You do get those challenges and things to deal with just because how of how interesting the show is, what’s going on with the island, and also dealing with flash-forwards and flashbacks and all these scenarios. You’re basically a different person in a way, because of the events that maybe have or have not happened.”

De Ravin says she’s currently working on episode 13 of 16 (the final one being a two-parter), and so far with what they’ve filmed, she says a few of her own questions about the show have been answered but not many. “There’s a lot to come right now – I just read the next script and that was like, ‘OK, maybe things are beginning to make sense…’ Also, you can’t really answer every single little question with the show. Then you’d just be like, ‘Why did I watch for six years?’ There has to be some things that are left up to your interpretation or chance. That’s just the show: It would be odd for them to wrap it up and be like, ‘Here are the answers to everything. Bye!’ ”

Lost wraps its final season filming in Hawaii in the beginning of April, but luckily for de Ravin, that doesn’t mean moving back stateside. Unlike Josh Holloway and others who relocated to the islands, de Ravin opted to commute to Hawaii during her stint on the show. “There’s quite a lot of downtime, and though I have Hawaii, I’d rather spend time where I’ve been based, either with my family in Australia or in LA,” she says. “I think I’d have the so-called ‘island fever’ by now. Or I’d just be like a surfer bum chick who’d be on the beach all day. It’d probably be good if I’d ever tried to surf.”
