Okay what in the HECK just happened! I've lost control of the situation!!!!

Okay so it's love day in my game and my Sims are newlyweds. I have them go on a date to Club Calico. Well they were making out all lovely dovey PSA and all that noise. I'm just watching and smiling, all of a sudden L. Faba came over and started making out with my male Sim, right in front of his wife, and he didn't stop her. And then L. Faba started getting beaten up by Agnes Crumplebottom who for some reason was also at the club, lurking!

What is going on!?? I am so confused. XD (free love plan is not on which is even more confusing)
This game is hilarious!!!!!
