So how did it end again?

I was excited about my Monday lineup of shows last night (House, Bromance, The City), but I remember going to bed disappointed. House was fine, Bromance was quite funny, but The City really kind of pissed me off. It started out with such promise-the writers had Adam throwing a party, on both Kat and Allie would be attending. (I think this is kind of funny since New York has 8 Million people, and he picks a chick that is friends with Allie's friends, but whatever....And why does Sam need to go to this thing, much less Kat?)
After Kat tells Allie though, this whole episode just goes to crap. In fact, as I write this, I'm not really sure what happened. Adam kept telling Allie that Kat was lying. She didn't believe, then she did. He kept "lying" or maybe he wasn't. It gave me a headache.
Then Whitney and Jay got into a fight over it. WHAT? How did that happen? It was like Whitney was TRYING to start a fight.
As big a beyotch as Olivia is, she was right, THAT IS HIGH SCHOOL PEOPLE! If Adam wants to cheat on his not-so-hot model girlfriend with an ugly Katerina, let him do it. It was an UGLY CONTEST when the two of those girls talked at the party. Adam can do better than either of those chicks. I am guess though that Allie makes some serious coin and THAT'S why he is with her.
But in that case, why would he ruin his meal ticket to hook up with ANOTHER ugly girl? You'd think that if you are going ugly, at least go rich ugly. And maybe THAT'S why he is proclaiming innocence.
And maybe Allie realizes this too. And is Kat just saying this to be on TV?

And why did Whitney pick a fight with Jay? What happened with that?

Nevan needs more airtime.

Hopefully the return of Nip/Tuck will settle me down a touch.
