There's a watery, shaky laugh, and all Matt's joints feel like they're going to give way at once. It feels so damn good, it feels like he's dreamed about for months and months. He wants to stay like this, wants to breathe in Shiro's smell, the way he's broader and more solid, but still feels like home.

"Yeah. I. Space growth spurt, I guess." It's a stupid joke, and Matt knows it's a stupid joke and he doesn't care.
