If Desmond had to name a way to end something, especially someone's life, he would say that giving them a flower burial would be pretty beautiful, but what if they weren't flowers? If they were clusters of fire so highly condensed that they vaguely took on the shape of a fiery rose; that would then be a beautiful way to bring destruction on someone.
