What are you talking about? Of course I need you. You're my twin, Tommy.

[Like it's the most obvious thing in the world, because it is. Because it doesn't matter that they've only known each other for a short time, a couple of years. It doesn't matter that they aren't blood relatives. Tommy is his twin. They share a face, bit more importantly, they share a bond that goes deeper than bone. They share a soul. He's lucky to have understanding parents, and he loves his little brothers, and Teddy--was...was complicated, but Tommy? There's nothing complicated about that.

His arms tighten just a fraction more at Tommy's last words, and Billy clings to his brother like he does to what he hears.]

I know we're--kind of a lot, sometimes. My mom and dad, they just...wanna help, and understand, and even I get annoyed sometimes at how hard it is to get any time alone, especially with Matthew and Lukas running around, but--you're family, too, Tommy. You're my family.

When we get back--will you come home? Or just...think about it.
