Cindy covers for Casey, it's what she does. It seems most of us agree Cindy and George take enabling to a whole new level, and were doing this long before Caylee was murdered.
The topic of Cindy being the first to hold Caylee and Casey's resentment over it have been brought up time and again.
I don't think it is a big stretch, considering what I have seen of this family's dynamics, for Cindy to ask Casey for info on the nanny, getting stalled, and if she pushes, little ms. princess perp throwing a hissy fit, throwing up how Cindy held Caylee first, how she is trying to take over, etc. etc., whereupon Cindy, being the martyred co-dependent soul she is, would drop it.
