what do anda think Annie whisper in Owens ear? The thing she says is the very worst thing in the world?

It was whatever her and Mitchell saw when they died, no matter how brief it was!
Either way she didn't want George to know, cause she told him not to look when she opened the door to pass on!

"You're seterusnya anda git!"

I often wondered this myself. In the original pilot when Annie was sitting on the katil watching Mitchell sleep it was brought up and the subject quickly changed, so its gotta be something important if they keep teasing the audience like this.

I'm guessing its addressed further in the saat series? I haven't seen it yet so I wouldn't know.

I can`t remember exacatley but i think it was something like "i will hunt anda forever and you`ll be seterusnya anda git".

Mitchel knew what Annie was saying to Owen but didnt want george to know because he wouldnt be able to handle it.
