Jace sat on the train listening to the 'click, click, clack' of the trains wheels on the steel tracks. He was on his way home from a demon job just outside of the city. He wanted to go home and see his family; Clary, and 2 children Arriane and James-or also know as Jamie. Arriane was only 7, and Jamie was 2. And, with Jace at 36, and Clary at 35, they were still energetic to keep up with the kids and their crazy hours.
Jace was ecstatic when Clary told him she was pregnant with Arriane, and then again with Jamie. Arriane was born with his golden hair, and Clary's piercing green eyes. Arriane was more like her father in some ways. Example, his short attention span. Jamie had strawberry-blonde hair, and Jace's golden eyes. And Jamie was more like his mother.
Arriane wanted to come with Jace when he went on a demon job, but he said she was too young, and the demon's he was with were very bad and dangerous ones. He'd always tell her when she's older, she could come, and then she'd pout and walk out of the room. He'd just laugh at his daughter's playful anger.
He opened his wallet and looked at the picture of Him and Clary when they were younger. They passed through so many complications, but in the end, love won, and that's what Jace wanted.
All of sudden he felt the train jerk forward. He moved forward with the train as well. Once he straightened up, and he heard announcement say "All passengers to New York, this is your stop." He got up, got his bags, got out of the train and on to the platform.
He got a cab, and asked the driver to drop him off a block away from the Institute, since to mundanes', it was an old church.
Once he was dropped off and standing in front of the Institute, he felt instantly home. He opened the door, and walked inside. Clary must have been waiting for him, since she ran to her husband like she hadn't seen him in 20 years, instead of 2 days. He picked her up, and twirled her, and kissed her as his kids came running in.
"Daddy!" They both yelled. He put Clary down so he could greet his kids. He picked Jamie up, and put him on his hip so he could let Ari grab his leg, and Clary pulled him to her with her arm, and he kissed her cheek.
This was the happy ending the Jace wanted, and he had it.
