Marco laughed nervously, seeing that she was still nervous as well, but he was too happy to find someone in the darkness. Someone that wasn't a monster, which was his main fear. "I'm Marco," he told her. "I didn't expect to find anyone out here so late. 'Course I didn't expect to be out here so... Oh!"
In a quick motion, Marco shed his backpack, dropping it on the floor and pulling it open, before kneeling next to it. "I have supplies. Food, mostly, just in case you needed any. There's more back at the museum. Did you want some chips? Or water? I've got enough for your Pete friend too."
