Peeta, clearly, is more comfortable with this world than Panem as well. He feels like he has some measure of control here like he can help steer his future. He's glad that Katniss feels the same way because if she didn't...well, they probably wouldn't be here.

Children are something that Peeta already wants, but he doesn't want to pressure her. They're both still very young and there will be time here to have children. Besides, he wants to make sure that their life here is solid and safe (as it can be) before they bring children into it.

She is almost always the cause of his happiness; she ought to realize that by now. Those goosebumps across her skin have their own effect on him; it's a warm, satisfied feeling.

He shrugs a little. "I think she might have learned her lesson," he jokes. "We might ought to consider our own place though, something close by."
