Antagonist - Protagonist

Make it clear what each WANTS.

And don't forget that each has a  WANT and a symbiotic CO-WANT

In other words, a WANT and a NEED
In other words, a WANT and a MOTIVATION

The WANT revolves around a person, place, or thing.
The CO-WANT revolves around a person place or thing.

One character says, "I want to put up a picture of my dead mother."
Another character says. "No.  There will be no pictures of her in this house."

That's WANT

Here's CO-WANT
One character says, "I want people to remember her when they are here.  She was a strong woman and made us who we are.  I want to keep that dignified personality alive here."
Another character says, "I want people to forget about her.  She was a bitch. I want to let loose in the house and not think of her looking over my shoulder."

1) Picture of mom
2) Loose Personalities vs. dignified personalities

And the CO-WANT should suggest a relationship conflict BEYOND the protag and antag.
