Edit to the above post:
Three main factors come to mind:
1--she may not have been confident AB could handle being involved in his daughter's disposal without falling apart at the seams;
2--Somewhere deep within, a twinge of actual shame might have made it difficult for her to actually show AB whatever it was she had done;
3--EB may have intended to "frame" AB to cover her own arse; to do this, she would have to keep AB in the dark so he couldn't rat her out with solid evidence.
