What did Betty Bright tell Lake Windsor's coach about Antoine Thomas?

Betty Bright told Lake Windsor's coach that she knew Antoine lived out if district, as did a number of other people..... and that if he turned Paul in.... she would do the same with Antoine.

"Do you know where she lives, Coach? She lives in Tangerine, with her mother and her brother. Do you know who her brother is? He's Antoine Thomas! Your football star at the high school here? Antoine Thomas lives in Tangerine, too. Now, are you sure you want to play that county-eligibility game with me?"
Coach Walski took a step back. His face seemed to flatten out, like she had hit him with a shovel. He said, "I'm sure Antoine Thomas has a different address."
"I'm sure he does. But he doesn't live there. I can take you and show you, or any officials of any commission, exactly where he lives."
