jon headed downstairs to see his (now her) dad
" Hey Dad" jon asked
"jon... is that you, you had sex! i'm proud of you, you've finally become a man, well that is if or when you have sex with a guy," jon's dad answered
jon noticed that his (now her) dad looked a little different, jon guessed that when you had sex and swapped sexes you got alot of their characteristics, that's why he (now she) resembled Sarah somewhat so if he had sex with a guy to turn back he would look somewhat like that person.
apparently switching sexes was a kind of right of passage for people now too.
"well... I'm gonna go over to karyn's" jon said
"all right see ya later jen" jon's dad answered. chuckling
