Sawyer in “What Kate Does”

It's not your fault she's dead... It's mine. She was sittin' right there, right where you are now, tryin' to leave this place - and I convinced her to stay. I made her stay on this island because I didn't want to be alone. You understand that right? ... But, uh... But I think some of us are meant to be alone. [Sawyer glances down at ring he's holding] I was gonna ask her to marry me.
