Thanks, I'll check on that.
I just had a crazy idea. I think it was Kim who told the security guard that Crystal was drunk. When the guard calls 911, she does not know what color Kim's car is, she has to ask Kim. So the the guard must not have gone out to see Crystal. So the guard's opinion of Crystal's condition must have come from Kim.
Kim is telling the security guard what to say. You can hear Kim in the background of the 911 call.
I think I just put a hole in my arrival time theory.
If Kim and the guard had been out to the car trying to talk to Crystal, etc., the guard would have known what color Kim's car was in the 1:22 call.
So now I think Kim did not ask the guard to call 911 until right at 1:22, and at that time, the guard had not been out to look at the car yet.
This would put Kim's arrival back near 1:22 again.
