Rex was itching to join the rebels fighting the empire. It was built into him to want to fight and defend those he loved. Every part of him ached to be out in the war. Of course he loved Ahsoka and his children, and it had been 17 years since the Clone Wars ended, but it was different for him this time. In the Republic army, they were bred, faceless, expendable soldiers in slavery, being forced to fight in something they didn't really believe in. If he joined the Rebels, he would have made the decision to fight for a good cause on his own terms.
However, Ahsoka felt very differently. She still had that Jedi instinct to try to preserve life and after she was used in the Clone Wars, she didn't want anything to do with fighting. It was just not who she was. Her trust had been broken and she didn't want to make the same mistake again. Ahsoka now felt all her responsibility for her children and husband.
Rex occasionally took out his blasters to keep his aim sharp. The kids came over to have a go as well. Aleah was the eldest at sixteen, then the twin boys Archer and Zeb who were fourteen. They were all talented when it came to shooting. Ahsoka also taught them to use the force because they inherited it. Rex and Ahsoka also taught them basic hand-to-hand combat. They were very capable, at fighting.
Rex stood, aiming, aiming, fired. Hit the target. Bullseye. He smiled.
"You never lose it," Ahsoka said behind him.
Rex smiled and walked to his wife. He planted a kiss on her lips and pulled her into a hug. He cherished everyday he had with her as it could've many times have been taken from him. Ahsoka still had a young face, beautiful blue eyes that still had its spark, and a smile meant for him. Rex had aged quickly like a regular clone, but with help from the force and Ahsoka, he had been able to stay in his late thirties or early forties.
After he had released her he saw her that dreamy smile that she got after certain moments between her. Their first kiss, their wedding ceremony, the first time they made love, when they found out she was pregnant, when she felt Aleah moving inside her, when she first held Aleah in her arms, when Aleah started walking and talking. There were so many times when she had that smile but it never lost the effect it had on him. He felt his heart race and he felt like the luckiest man in the world.
"It's part of who I am," Rex said.
Ahsoka frowned, she knew what he was hinting at.
"Rex, you know why you can't,"
"I know, but it doesn't stop me from wanting"
Ahsoka sighed in frustration. She hated when he talked like this. She didn't want to argue so she left it. They walked to the house, Rex secretly wishing that he could have both his family and fulfilment of his sense of duty. He didn't know who would change this for him. But they were closer than he thought.
