I didn't get it. Aha, I thought, when I saw this thread. Still none the wiser. Even jo's link didn't help. The director said its obvious what happened. Not to me?
Very disappointing - I kept waiting for something to happen and it never did! Also got a bit fed upwith the contiual backing and forthing between days.
I've just watched the last episode! That's four hours of my life that I won't get back. If I wanted to make up my own ending I'd write a friggin screenplay.
