Thank you! I think I'd scare myself if I'd written out the creepy bits, lol. It's part of the reason why I needed Harry to get know know Snape in his memories first -- Harry is a very accepting person, but even he wouldn't so readily warm to clone!Snape if he hadn't already made a connection with Snape's mind and knew that the same consciousness now pilots the cloned body.
Harry and Ginny are in a semi-open relationship, a decision they made early on to deal with both of their celebrity status. They're also first and foremost really good friends who trust each other completely. Snape got the special privilege of going beyond kissing with Harry because, in a way, he's always been the third wheel in the marriage. Harry looking into Snape's Pensieve is a habit, and Ginny both knows about and has come to accept it. Now that Harry's finally admitted to his obsession, I can picture Ginny sending Harry off to "spend time with Snape" whenever she leaves for a Quidditch tour ;)
