Sepet Ending

There's been a lot of debate on this, the ending to the movie Sepet. Who answered the phone when Orked called Jason? Cos in the previous scene it showed that Jason had died in a motorcycle accident. (Well, ppl only assume that he's dead. Maybe he's just seriously injured.) Some ppl say Jason answered the phone before he crashed, some ppl say his bestfriend Keong answered the phone for Jason, some ppl say it was Jason's spirit. Some ppl say it was just Orked's imagination, or something that she did to calm her mother who was crying deliriously beside her...

I really don't know. You gotta ask the director/writer herself. I just remember myself saying at the end of the movie, "Eh tak paham laa! Tak puas hati... saper yang angkat phone tuh?? Eeeesh."

What's your take on the ending?
