She was always a good rider while he preferred the steady earth beneath his feet.
But when he left, he took a horse. He felt guilty stealing but he felt also too hurt to really care.

They have enough horses … he headed down the Kingsroad torn between the choice of returning to Kings Landing or heading somewhere else. Maybe Braavos? It always sounded beautiful there, when Ar … No! Lady Stark. It's Lady Stark now, don't forget it. Never forget it again!
When he heard the rider and turned to look, it was her, bowed deep over the neck of her horse and with a grim look on her face. Gendry felt hope stirring, but he knew he shouldn't.
"STUPID!" she yelled.
"Why are you here? You have to go back, to …"
"Shut up! I talk, you will listen!" she manoevred her horse close to his. "You. Will. NEVER. Leave. Again."
"Did I miss, that they establish Slavery in Westeros again?"
"Stop being a stupid bull! I don't want you to leave me ever again. Understood?"
There was more.
"Why?"

Suddenly she looked utterly frightened and again like a girl of five-and-ten, but also so much like Arya in her torn dress and leaves in her messy hair.
"I was alone such a long time. I don't want to be alone anymore." She hesitated "You can kiss me again, if you want to."
Gendry swallowed. "That's not what I want." He turned his horse.
He heard her curse: "You stupid bull! What is it you want to hear?"
"I want you to want to be kissed by me." He shouted without turning around.
When he heard the horse behind him again, he was too slow again.
Suddenly he was pushed out of the saddle and Gendry landed hard on the ground with all the air pushed out his lungs. He desperately tried to breathe, when he felt her lips on his and her breath filling his lungs.

When he opened his eyes she sat on his chest, tears in her eyes but with a broad smile on her face. Her hands clinged to his hair and she pressed her lips again on his. Suddenly she sat up, unsure: "Am I doing it right?"
Gendry was still not sure if he hurted himself at the fall or not, but he was beyond caring, actually. He laughed and answerd: "Maybe the next time, ask me to dismount before you threw yourself at me and knocked me off. So I'll be warned and we can make the best of it."
Arya nodded with a serious expression and then - smiling - kiss him again.

This time, they made the best of it.
