Oh i guess how the party will go on. There will be some polite discussions, some dance, then Adam will make his speech and announce the bad news.
Jenny will certainly get mad and there will be some scandal then she will storm out with you and the girls and you will have to think about how to solve this problem. Punching Adam would be the most stupid thing to do, prove that you are a dumbass peasant who thinks he can solve his problems by punching people!! He would press charges against you and you would find yourself in jail the next day. Expelled from the college, stuck in a cell waiting for Jenny to pay to get you out and with no place to go.
We can just hope that jenny will keep her house, but as Adam said it's not sure, maybe you will all have to go live in a hotel and start to look for a job, maybe in Jenny's restaurant.
