Why do we think that is true?

Because they showed that she learnt it in order to be able to escape him.

Why do we think that is true? If it is, then I have misjudged Jin.

So you think she was lying to him from the start?

Ok. Sorry Jin. Not the first time I've blamed a character for his creator's mistakes. I much prefer a not-dumb Jin.

the idea that an educated and prosperous young Korean would understand no more English than what Sun showed publicly on the island seems absurd to me.

It doesn't to me, based what I've heard from my in-laws who lived there for two years, and my own experience visiting them there. English is much rarer than you'd expect.

Plus, as others have pointed out, whether it's realistic or not, it's canon.

I really don't think it's dumb. There's no reason for Sun to know English. Her father conducts the business, not her. Everyone in the world doesn't know English. I was reminded of this when I spent three weeks in India.

The real question is, why do the writers treat language like an on-off switch, when it's not? English is available all over the place, on cable, on newsstands, etc. I can see as how someone who doesn't have an interest in international business wouldn't bother to take lessons, but I bet most affluent, educated people in foreign countries, especially foreign countries that still have US military bases on them, could mumble out a couple of English words and phrases.

(Conversely, now she's been revealed, Sun will turn out to speak perfect English, with minimal accent, no vocab deficits, and never fumble the verb "to be".)

For that matter, I've never taken a Chinese lesson in my life, but I can guess at a couple of basic words, based solely on movies I have seen -- and Chinese isn't exacty the language of cultural imperialism.

You don't have to "speak the language" to have a basic awareness of the language, the way that you don't have to be a baseball fan to say a guy struck out, or got caught looking.

Even when that's going against Jessica's (and mine, to be honest) experience?

It depends on the person. My SiL lived in Luxembourg for 4 years and didn't learn a word of the language. Not "how much" not "soap," nothing. She limped along on some French phrases and pointing a lot. Luxembourgois (sp?) is not an easy language, but my brother managed to pick some up--it was spoken all around them every day, but she just didn't have an ear or an interest.

the way that you don't have to be a baseball fan to say a guy struck out, or got caught looking.

I, for one, have no idea what either of these means. I find it pretty believable that Sun didn't speak English. From what we've seen, her father was over-protective, and not giving her opportunities like that would be another means of maintaining control over her.

Heh -- maybe Jin just hasn't had the opportunity to use "courtesy patrol" in a conversation.

The only English-language television I watched there was available through AFN (Armed Forces Network), which you can only get if you're living on the military base. American television programs on Korean channels are largely dubbed. Movies are generally released in English for a couple of weeks in very limited release, and then go wide dubbed into Korean. It would certainly possible to pick up some English from the media, but English is far less pervasive in Korea than in, say, India.
