Summary
They were moving through a quiet residential neighborhood in Shelbyville. The houses were spaced apart, separated by tall oaks. It was peaceful. Until, Haley suddenly went rigid.
She didn't bark. She just stopped, her ears perking up, her tail vibrating.
"What is it, girl? See a squirrel?"
Dick looked ahead. Standing by a wooden telephone pole was a man. He was tall, broad-shouldered, and wearing a dark blue collared-shirt with a brown leather jacket over top. He had long, dark hair tucked behind his ears and a look of focused, quiet intensity that made Dick’s internal "vigilante" ping instantly.
The man was currently struggling with a roll of packing tape. His left hand was shoved deep into his jacket pocket, while his right hand tried to flatten a piece of paper against the pole.
OR
Alpine is missing, so Bucky Barnes puts up posters to try and find her. Dick Grayson just so happens to be in the area.
