I also after rereading, realized that she was telescoping what she personally knew and what she had been told. I think she was told that nat was with Joran later in the evening, she knew from what she was told that they left together. She didn't see it. And I think at the airpport she was told nat was missing and that the cell was in the room. So she didn't call.
It was a confusing disjointed interview via phone with connection breaking up so it came across that way.
We were all together, dancing, and Natalee was only with Joran towards the end of the night.
GRACE: So when you saw him later in the evening with Natalee, what were they doing?
WEATHERLY: I didn`t see him later in the night with Natalee. I saw him in passing, and that was it.
Sorry, these girls know more than they are saying.
