On shooting his death scene ''I remember standing there, and then a cloud came over. I'm holding the dynamite, waiting for the cloud to pass. It was one minute, two minutes, and nobody was breathing. It was absurd from my point of view. There were 100 people waiting for me to explode.''
Ian Somerhalder (Boone Carlyle)
When he died Season 1, episode 20
How he died Suffered massive injuries when the tree-lodged plane that he was in fell to the ground.
On surviving one plane crash, only to die in another ''The irony aspect of it kind of killed me literally.

Cynthia Watros (Elizabeth ''Libby'' Smith)
When she died Season 2, episode 20
How she died Shot by Michael moments after he gunned down Ana Lucia.

Then Terry shows up and he's chatting with everybody and goes, 'Have you guys read the new script?' Everybody says, 'No. We've been here.' 'Well, I kill the new girl.' And then everybody goes [awkwardly], 'This is Marsha.' And that's how I found out I was dying.''
Mira Furlan (Danielle Rousseau)
When she died Season 4, episode 8
How she died Shot by Widmore's men while trying to escape with Alex and Karl.
On her death scene ''It was very brief. I thought that Rousseau needed more. I would have loved for her to have a big dying scene. Especially when, for four years, I was trying to find my daughter, [Alex], and I finally did, and then nothing happened. [Laughs] You take those things with humor. I tried to take it gracefully.''
Harold Perrineau (Michael Dawson)
When he died Season 4, episode 13

On his mode of death ''Some of the deaths you can come back from. The Island was really mysterious. One, I wasn't on the Island, and two, the boat blew up, so I thought for sure Michael was gone. If he's going to go, we're just going to obliterate him. And I thought, 'That's perfect. Like, really, just let it all go.'''
Rebecca Mader (Charlotte Lewis)
When she died Season 5, episode 5
How she died While jumping through time, Charlotte developed nosebleeds and headaches until she ultimately collapsed.

Dan Snierson and John Young
