If people were looking at them, Bunny didn't notice or care.
The outpouring of emotion is something they both needed, and she didn't make any move to cut it short. When the zombie wave hit Harlan she'd discovered how quickly everything could be lost. This moment can't redeem everything they've both gone through, but it was the start of something new, something better. And suddenly Bunny could remember a quote, though not its source: Journeys end in lovers meeting.
By the time Nate stood up and gathered her in his arms, lifting her, Bunny's tears had been traded for laughter. She wanted to hum or sing out her joy, shriek like a little kid on a tire swing trying to reach the sky. Instead she settled for taking his face in her hands as well, as soon as she was back on her feet, so she could kiss his forehead, his cheeks, his chin, his mouth.
"I am," she agreed, grinning. The words were sweet in her mouth. "I'm coming back with you to ... the Capitol, you said? But there's nothing to get. Everything I own is right over there." She nodded to where her pack was sitting, next to the chair she'd been in when he arrived.
Bunny had debated all morning about whether packing up her things would jinx the whole encounter, or whether it simply acting in good faith. In hindsight, of course, she could see it was the right call, but she must have put everything in and out of the bag at least three times before finally deciding to leave it all in there.
