^None of what I just posted explains to me how this went down. If we accept that he didn't know he was a she when they left the disco, which appears to be the case, then - given news that he was NOT post-op - he must have noticed once they got in the hotel room and disrobed.

Now.....the kicker. Two used condoms in the trash can.

Somebody was doing something to somebody.......

So, after consummating the act - twice - all I can come up with is he freaks, says what have I done, OMG I'm a fag, did my buddies know he was a she? Will they all laugh at me? And, in a fit of self-loathing, panic and terror, he kills the object of his hidden desires.
