Steve/Natasha, uhhhh Zombies? (for starspangledspandex)
It says something, about life in general, that Natasha can still be surprised; something not so great, she muses, as she drives a knife through the eye of what was once her favourite analyst in the SHIELD tombs (a nickname which now sends shivers up her spine). Behind her, she can hear the whoosh and thunk and thump of Steve using his own shield, hear it ricocheting off the walls to return to him, and she's glad that he has a weapon of distance, that he doesn't need to be up close and personal to see that there's no life to leave the eyes of the herds they're mowing down in their single minded focus to get out of the Nevada base alive. The world goes to Hell, and they keep marching on - she feels his hand on her shoulder, offering support, turning them both down another corridor to break out into the sunlight and sprint for the humvee, and she wonders if they're always going to be running full speed into a future neither of them ever wanted to live to see.
