AHHHH!!! You finally updated it!!! And once again your writing solidifies you as one of my favorite authors (if not my favorite) on ficwad.
No, I get that it's not OOC. Something is definitly not right and Sasuke seemed to know something about it. Very well done! I just ask that you take good care of Kakashi. I love him; I love what kind of a daddy and hubby he is in your story. I know that if you didn't screw with his happiness there would be no dramatic tension, but just make it "all better" in the end, okay? ;)
