Neal thinks he’s a man of mystery, but she lived with Byron a long time. She sees the way he looks at Peter, and more rarely, Elizabeth, when she comes over. She’s seen the way he looks away whenever they kiss or hold hands. And, later, she sees when he stops looking away, starts teasing them like they tease each other, sees how he brushes Peter’s hand with his own as they’re walking, how he kisses Elizabeth on the cheek as a hello.
It’s not her place to judge. The Burkes are good people, and Neal deserves to be happy.
