A mistake. That's what this was. What was she thinking, inviting O'Brien up here? What happened to the whole not wanting him for a friend thing? Friendship wasn't supposed to be part of her equation anymore. More people to miss when they died? Yeah, she didn't want that.
It was something she missed, though. Despite her tough exterior, she missed having people to talk to, to bond with. Couple that with O'Brien's persistence and loyalty, and Leah had one hell of a conundrum to work through. He'd weaseled his way in with no small amount of effort and, damn him, it was paying off. For him. In such a short amount of time, Leah owed him so much, that she no longer felt comfortable ignoring it.
The howling wind was loud, making it impossible for voices and sounds to be heard unless they were loud. On the one hand, it drowned out the incessant moans of the zombies down below. On the other? It allowed O'Brien to sneak up on her. His greeting startled her, the only indication being the sudden twitch of her shoulders. She looked over at him, nodding a return greeting, before following his gaze back to the sky.
"Colder, but less stir-crazy than I was down below," Leah answered honestly. "I'd prefer the cold to the crazy." She resisted the urge to moisten her lips. It wouldn't do anything other than make her lips chapped.
"You've been making yourself scarce lately. Taken up playing hide-and-seek?"
