Kate knew he was behind her the moment she heard the footsteps. She had always been able to tell people apart just by listening to the way they walked.
Jack walked today with a purpose.
Kate turned to face him and gave him a short glance.
"You're wearing a purple shirt."
He was caught off guard. He took two more steps toward her, faltering just a little. She'd interrupted his thoughts.

"It's not purple. It's blue."
"It looks purple." Kate smiled. They stood in the dark street, a little too far apart.
