Even with the ?'s surrounding the 6 min. call, their separate searches on the car temps needed for death, her comment at the day care center is still very suspicious. Almost like a rehearsed line in a play that was uttered in the wrong spot. Same with the convo at the jail, "did you say too much"? I think she's the one that has said too much.
I agree. But she had no one to counsel her. Maybe "the PLAN" was a bit thwarted and she was having to ad lib. JMO
