He's on the run again. Actually he's been on the run pretty much his entire life. Sometimes he wonders if he'll ever have the chance to be free. His eyes are trained on the young couple sitting on the other side of the cafe and Ward envies them. He's jealous of the way the guy touches his girlfriend. Jealous of how carefree and innocent they seem.
Because they are not tainted, they're not ruined. They have their entire lives in front of them; to live and love and grow and Ward doesn't have that. No matter how much he wants it, he'll never have that. He'll never be able to be with the woman he loves. He'll never be able to hug her and kiss her and make love to her in the early morning. All because he screwed up everything for John.
So that's why he envies the people, the happy couples, around him so much. Because they have something he'll never be able to get.
