Katniss had trouble sleeping on the best of days. But, in the way that the world around her had a habit of doing, too much had been dumped on her all at once. First Peeta's disappearance, then the wild boar hunt that she had fumbled and ended up getting herself hurt. Then Peeta's reappearance, and then Gale.
For a while, she'd been glad to have Peeta's constant company, the security of his arms to hold her while she was stuck in her hospital bed. But she'd left medical, and she was back in her room with the roommate that she barely knew, and Finnick and Annie in the other room. Nights here hadn't been so bad when she'd been able to exhaust herself out in the woods all day, hunting, gathering, carrying back food. Now she had almost nothing to do, and it was driving her crazy.
She was avoiding her room, avoiding everyone else a little bit too, and nights were the one time when she (usually) could find some peace and quiet in the bunker, away from everything. It wasn't the same as being out in the woods, but it was something. Instead of going to bed like she'd told her friends she would, she wheeled herself out into the hallway, and just kept pushing herself around, enjoying the burn of the muscles in her arms and back, hoping maybe she'd exhaust herself and be able to sleep. On her own, this time, because Peeta's arms had started to be a little too much for her to handle.
It wasn't him. Everything was too much for her to handle.
She'd stopped, finally, in one of the common rooms. She'd thought she heard people coming and ducked in here to get out of the way, and when she actually stopped, she was tired and achy enough not to want to move again. It was quiet in here, and she had about an hour of solitude — maybe two, her sense of time wasn't the best — before she was startled by the sound of someone else's voice.
Glancing up, she looked at the man in the doorway. At least it was no one she recognized. She didn't really want to talk to them, but she said, "Hi."
