Lost Season 3 Episode 18 (3×18)

I wanted to throw in a comment here. When the  injured helicopter survivor woman (Naomi) says “eu nao estou so”, Mikhail says: “she said ‘thank you, thank you for saving my life.’” But this is the WRONG translation, he deliberately lied.

What she said was portuguese and translates exactly into “I am not alone.” And now we know something the losties do not know, unless she repeats this in english at a later point.
