Summary: when did Jonathan O'Neill become Jack O'Neill? You'll be surprised.
a/note: no clue where this came from. Seriously, none. I was just wondering when he started to go by 'Jack'. This is what happened. (In my brain) so here is a tiny one shot explanation.

~~ Jack Be Nimble ~~

Jonathan O'Neill stood on the sidewalk of his street, his bicycle balanced between his legs as he watch in bewilderment as an elderly man bounced a small stone up and down in the air with an oddly shaped stick. He titled his head at the sight. The man must have been sixty or more, it was hard to tell. The stick in his hand looked like a flattened golf club, but made of smooth wood. The older man was yet to notice the eight year old boy watching him in perplexed silence.

"What'cha doing?" Jonathan asked. The elder man startled and the stone fell to the grass. He took a look at Jonathan.

"Testing out my hockey stick," he shrugged. "Just finished it this morning." He smiled. The approached Jonathan, the stick held out to him to see. It had no markings or labels. The wood was well sanded and the flat end was wrapped carefully in a protective black tape.

"What's it for?" Jonathan asked. The man frowned at him.

"You know ice hockey? It's a sport?" he asked, but Jonathan was unfamiliar with it. The older man sighed.

"Guess not... what's your name kid?" the man asked.

"Jonathan O'Neill." Jonathan replied. The man raised his eyebrows in apparent disbelief. The expression soon faded away and the man smiled warmly.

"You look more like a Jack to me. You know Jack is short for Jonathan?" he said, coming down onto one knee, the end of his hockey stick planted in the soft grass.

"It is?" Jonathan wondered.

"Sure. Why not?" The elderly man shrugged one shoulder. Jonathan considered this for a brief moment.

"Like Jack be nimble, Jack be quick?" Jonathan smiled. He liked the sound of 'Jack', certainly better than Jonathan. Yes, from now on, he would go by Jack O'Neill.

"Jack can have my hockey stick," the man smiled, holding out his handmade hockey stick to Jack.

"Really? I can have it? But I don't know how to play hockey..." Jack realised.

"Well you better go learn, son. I think you'll like it," the elderly man smiled at Jack. "You look after that alright..." He nodded to the stick. Jack smiled widely.

"Alright. Thanks mister!" Jack placed the hockey stick over the bars of his bike and took off down the road towards his house.

Cam stood up and smiled as he watched a very young Jack O'Neill take off quickly. He shook his head and returned to his house, wondering if he had changed the timeline just that little bit more for the better.
