She is dead and it's not known how she died. I think she is alive, but who knows.

Yes, the kid said that his mother (du na) was dead but I don't think they ever said what happened to her. I think you are getting confused with ha na adoptive parents. I don't remember their names, the ones who died when she was at the piano recital.

When do they say it was in a car accident?

I wouldn't be surprised if the kid turns out to be Ji Seok and Du Na's son. I also doubt that Du na is really dead, because the death of one of the main characters is too important not to show it. Unless they do some dramatic flashbacks later.

she's probably alive, she "died" off camera and we don't even know how.
