Rufio paused when he saw a familiar person walking through the crowd. Zoe, the older woman he'd met once by the docs. She was easy to see among the generic looking crowd, she was special somehow. Maybe it was her hair, or because she was so tall, or maybe because when you looked at her you got the feeling she might kill you on a whim.
He slowly pulled himself up, watching her walk. She was moving oddly and looked tired, but not in the vulnerable way. People like her didn't look vulnerable. He tilted his head, then threw a leg over the guard rail, climbing to the outside of the fire escape before letting himself down. There was one decent thing about living in a City; the entire place was more or less a jungle gym.
He dropped down to the pavement as Zoe passed him, then jogged over to catch up.
"Hey, old lady," he grinned, calling out to her so she wouldn't be surprised by him suddenly popping up at her side. "You look like one of the bus things hit you. What's up?"
