We find Asuka Langley Soryuu naked, bound and gagged on a bed in her quarters.  The question is not how does she feel about this, because it's quite obvious that she's pissed.  The question is who did it?  Was it Shinji, finally tiring of her constant abuse and teaching her a lesson - - or giving in to the feelings he denied?  Or was it Misato, to get her out of the way so SHE can make a drunken pass at young Shinji?
