Star City
Oliver scratched his white beard as he already fixed up the lair with Connor's help, it had been a relief to see Sarah, Ray after all these years. He almost forgot how they looked like, so much he had lost in these three decades. It had been quite a shock when he got back up to the surface it was quiet, people walking in the streets again, Star City abuzz with life. He was no expert on temporal mechanics but it seemed the timeline had been changed and the changes would come slowly. He felt his right arm, it was whole again.
''Way to go Sarah,'' he smiled. He recalled his old friend John Constantine saying time and space was a mysterious thing, the changes would not come instantly. The memories of the old timeline will disappear and the new ones will arrive.
The new Queen house was located in the place where the old Queen manor once stood destroyed by Grant Wilson, using materials from the old house he rebuilt it into a more modern place. The place was empty, perhaps by next morning the timeline will have changed completely. Walking up to his bedroom upstairs, he got into bed, threw the sheets over his body and closed his eyes.
The next morning, a sunbeam filtered the windows, Oliver heard the beards chirping as the pleasant smell of eggs and bacon hit nose. The first thing he noticed when he woke up was the different decorations in the room they were colorful and alive. Climbing to his feet, he walked into the hallway where he stepped on a doll.
'Moira you're going to give your old grandpa, a...'' Moira! The memories started coming to him, Moira Clayton his granddaughter. She was two years old, her mother was Sara Diggle. Despite their age difference, William and Sarah started dating five years ago. It had been a source of humor between John and Oliver that their children had somehow gotten together.
When he walked into the kitchen, Oliver's breath was caught in his lungs. It was Felicity, older but as beautiful as ever. Memories came rushing out like a dam bursting, he and Felicity were married 2017, their daughter was born a year later. Whole birthdays, vacations, every event was coming back.
''Morning sleepy head, breakfast is ready. William, Sara and Moira will be here soon, that little girl is going to turn the place upside down.'' she smiled. Felicity noticed her husband's stunned look. ''Oliver what's the matter?''
The man known as the Green Arrow could only smile. It was all okay now.
''Nothing, everything is okay now.''
THE END
