I admit after reveiwing the show again it does look like there was some creative editing going on with the saki and Lisa, but she did look a little bent and she was leaning and laughing alot ( more creative editing?) To me she displayed the classic symptoms of college age bar room/club girl drunkenness syndrome.
I've seen it first hand and I tell you she looked or was made to look like a silly collage girl giggle way to much and completly out of her element. The only thing that would have topped that off was her praying at the porcelin alter and crying 'why oh, why. never again".
