Q: How do you think she (Sun) became pregnant?
Yunjin: I don't think - I like the theory, and this is only mine, I like her to be sort of like the Virgin Mary, that it wasn't a guy who made her pregnant. It just happened, sort of like the island did it. The monster did it (laughs).
Yunjin : Divine Intervention?
Kim: That would be weird, her giving labor to like black smoke. See her come out of the tent with black smoke going 'whew! Glad that's over'. That would be really dramatic, wouldn't it?
