"Do I what?" Sam repeated, not following the question. At least not at first. When he realized, a shocked look crossed his face.
"Have a kid? Oh! No, I can barely take care of myself." there was a wry smile at that. The thought of having a kid, given the kind of life he led. No, Sam wouldn't wish that on any child.
He felt a little bad at the panic that seemed to have crossed the redhead's face at the mention of the kid getting sick too. He just wished he knew what to say to make up for adding that worry, but he didn't really have much advice to offer in the way of helping a child avoid getting sick.
