He had a point, and Katniss wasn't going to object to him repaying the favor. Debt was something she understood, even though she didn't usually think about other people owing her. Without further argument, she sat down at the table, blanket still wrapped around her shoulders.
At his question, she shook her head. She didn't want to talk about her nightmare. But after a moment she found herself saying, "Better not to let myself fall apart, right?" It was an echo of what he'd said to her just a few days ago, only hours before she'd arrived in New York. "It's harder here. It's not just Peeta anymore, it's everyone."
She didn't mean that everyone was appearing in her nightmares, although the one about Prim was new, specifically related to her fear that District 13 wouldn't stand up to the Capitol's assault, that her mother and sister would die in much the same way her father had. Exploding, suffocating, dying underground. She didn't know if that was something Finnick could understand, since he had no memories of 13. He'd had no one else in 13 to worry about, so far as Katniss knew, no one new to have nightmares about now that they were here. For his sake, she hoped all he had to worry about was Annie.
Although in some ways the worrying about everyone was easier to bear. It wasn't one pressure point, it was many. Spread out. She could distract herself from one by thinking about another. It didn't make her feel better, but it was enough to keep any one part of her heart from shattering into pieces.
She thought of the rope Finnick had given her at home, now stowed in a drawer beside her bed. Then she said, "I think I'm going to need to do more than make knots to hold myself together."
So far she'd found plenty to do during the day. Go out and explore the city. Go over to the strangely named Avengers Mansion and test their bows. Find supplies. At night, however, it was always different. It was too cold, the city too new and strange, for her to go outside, even if she had the energy for it. Right now she had Finnick to talk to, which helped, but she had a feeling both of them were going to need more of a distraction soon enough. Something they could do here in their apartment, together or alone.
