The "chummy" act with Sho is because she was trying to get rid of him quickly - they were outside, so they knew they might be seen (even with his disguise) and she was probably just pretending to be nice so he'd leave faster (when he didn't, she whispered in his ear - most likely a threat - and he left).
Not sure about the BJ shoot - I wanna know about that as well.
I'm a little confused by the set back and twist... what happened to the progress from the BJ shoot? It's like it never happened and what's with the chummy act w Shou?
