Need help with a intro/party scene.

Oh hai Writer's Block!

Okay, so here's what I'm stuck at:

I have the first act of a story I'm writing. The characters are Espers and a few mutants having a weekend party. It's an escape from their day jobs. Some are what you would expect from people who can read minds (lawyer, cop, psychologists etc). Others have various odd jobs (soldier, pharmacist, vet, auto mechanic).

I want to introduce the universe and some characters. The main protagonist is a slacker-type who's "working" as a private investigator because he burned a few bridges in the ESP community. His aide is a mutant who's a catgirl-naga. She took the job because the job market for cat/snake women is limited.

They have an open case, but they are between leads. So the slacker guy goes to see his esper friends, ask a few favors, grab a burger and then chill. His aide has friends at the party, including an esper with a secret.

Now how do I avoid:

• being boring

• Seinfeld Is Unfunny, old jokes and a chapter "about nothing"

• Mary Sue-ism descriptions

Yes I have writers block an welcome any ideas. Thanks fellow topers.

I think to keep it from becoming boring, you can try using the scene as a way to establish the protagonist and aides as characters. An Establishing Character Moment.

Also, do you have a conflict in mind for the party? Maybe the protagonist run into someone who has a grudge so the protagonist has to struggle against losing his cool and being kicked out.

There's a scene with fantastic racism latter. In my universe the hierarchy goes: humans -> espers -> mutants on the bottom. I was inspired by Brazil and my own experiences. Some cops are called about a noise complaint, one of them is a mutant and our designated hero uses a fantastic slur due to a brain fart and he insults his catgirl/naga assistant.

I like it, I have a couple of characters that could do just that...
