So, as far as getting Loki into the story, Rei seems to be late to Misato's apartment.<br/><br/>What if Ritsuko happened to see her leaving NERV, and decided that, thanks to her weakened libido, she needed some tests to determine her suitibility for the program.  (or if she'd need some lubricants and possibly aphrodesiacs)<br/><br/>Therefore, you get a cute scene in the lab with Ritsuko trying everything she can to get Rei aroused (under labrotory conditions) and possibly getting inadvertently hot under the collar herself.  :)<br/><br/>Seraph is onboard for the scene, if Loki is.
