Ben closed his eyes, holding on fiercely. Son. He'd never had a dad to call him that, and he'd usually hated when people called him 'son' instead of his name, but this – this was very different. Dean was his dad. Suddenly, the rest of what that meant came rushing in. He had grandparents and an uncle, even if he wasn't a Winchester the way the others were. Dean would be able to do those parent-teacher conference things. He was going to have an aunt and a cousin and maybe another uncle if Bobby wanted to be called that. When people asked him about his dad, he'd have a million and one things to tell them, rather than fumble for an excuse. His mom...
His mom really had lied. It hurt, to know that, even though he'd had to accept that to believe this test would say Dean was his dad.
He didn't want to think about that right now. He didn't want to be mad at his mom when she was so far away. Just like Dean had said, his mom had probably had reasons for it, reasons to protect him, and he'd already spent one night here after Dean brought up the test being angry with his mom about it. He just wanted to focus now on really having a dad. He couldn't play that thought over and over in his head enough right now.
He didn't let go of Dean, but eventually he pulled back enough to look up at him – after hastily scrubbing at his face to clear the 'dust in his eye'.
"Now what? Do we go get tattoos?" The grin that accompanied the question showed Ben wasn't serious, yet if Dean agreed, he'd jump on having a tattoo, right now.
