Blooper perhaps?

I was just rewatching pilot part 2, and got to the part where Jin is trying to convince Claire to eat the food, Now I literally just finished the Korean portion of my Languages class so I was happy I could pick up on a few things he was saying (mostly he's saying please, and excuse me when she grabs him, and no when she holds his hand on her stomach) but then I heard something odd, I rewinded a few times and I'm 99% certain he says hangoongal mot haeyo, which means I don't speak Korean'. Thought it was kinda funny, but I'm wondering if anyone knows if there's any translations for the Korean dialogue in the show, or was this just a blooper? x]
