You know you bring up a very good point, what exactly made that week particularly emotional? Because Nejame quit? Othewise all that we know now we only just recently learned so this statement wouldn't have made any sense in relation to just that week. So there again we are back at something big happening that week that made it particularly emotional.
Although I also happen to feel that maybe the anthony's knew much longer than nov, possibly all the way back to august, I just don't think they thought Caylee would be found or there were plans to move her and those plans went askew.
