Finally! Been waiting for her to clue Shiraishi in on what exactly she sees since before Takenaka's death. 

 I've been mulling over this today.. are kegare natural? It seems like the kami are life.. and the kegare are death. Both natural, both part of a cycle. Is that an accurate assessment? I can't seem to get my words to work for me better today, or I'd try and explain better.
