Ummm, are you saying that C is the grandparent of C, or do you have a typo in your example? Sure, the initial comment is not necessarily the grandparent, but in your ABCDE example, A is the grandparent of C, and C is the grandparent of E.

Maybe I'm just misreading your comment, but it has me confused enough to reset my password, login, and make this child comment.
