What do 你 think, could Rin be Kagome's ancestor? They do look a lot alike. Here is a picture of Rin grown up.

That picture is so cool!!!!!!!
And yes, they look pretty much the same and it would be so funny that if they were family they both married to inu no taisho's sons.

yes it is a possibalty. Rin is cute and Kagome is.
