Authors Note: Well I think I forgot the I don't own Inuyasha in the first chapter oh well. - There it is now. So I had completed Sesshomaru's Twin? and found that some wanted more well I had completed the I thought of making a sequel than I thought that you all might want to get to know Sho and Rin so I think a prequel will do just fine. This is how the two got to be so cunning. Well I hope you enjoy the story. ^_^

Oh and flying lizard is really a type of Pterodactyl. But I liked flying lizard better.

Rin had found she wanted to explore the past without her mother or father so she went to find Sho. Who was eating an ice-cream cone and looked like he didn't want to be bothered at the moment.

'Oh well I guess it is karma.' She thought as she touched her brother's back and fell through time with him.

Both looked around and found themselves in a place they didn't know. A loud roar could be heard as giant leaves rustled in the distance. Sho looked to his sister with a cross expression on his face.

"You couldn't have waited until after I finished my triple rocky road?" He asked her to which she just shrugged.

"I was bored what do you want." She asked him but he couldn't answer as a small roar could be heard.

Both looked down at the baby T-Rex and their eyes went wide. "Uh Rin exactly how bored were you that you sent us this far back." He said in a small voice as he kept his hands behind him.

She didn't answer as she got up and dragged Sho with her. Both were panting by the time they got away from the squalling baby dino. But their run wasn't over as the winged verity started to swoop down on them. Sho was captured in a clawed foot and taken off into the sky.

"Help me Rin!" He yelled as the flying lizard roared.

'Oh brother mom is going to be so mad if I lose him. As well as father who likes Sho since he is a boy.' She heaved a heavy sigh as she went after her brother.

She found him in a nest of eggs that looked about ready to hatch. His golden gaze locked onto her blue one. And she knew he was going to be telling on her. Landing without being seen by the one that took her brother.

"Where have you been I thought you were going to just leave me." He cried looking around at the giant eggs.

"Yes well I didn't want to lose my only form of entertainment seeing as you can't be replaced." She said not looking at him while blushing.

"Hey Rin do you smell that?" She looked at him and nodded.

"Yea it smells like a volcano that is ready to erupt." They looked at one another and then at the sky.

Smoke was coming from the top of the mountain that really wasn't a mountain but a volcano. Both children paled at this but things got worse as the eggs started to hatch. Small sounds could be heard coming from the eggs until tiny but not so little heads appeared.

"You know if we weren't about to be eaten by these guys and a volcano wasn't about to blow above our heads I would say that these guys are kind of cute." Rin said with fear in her voice. Sho face palmed as he tried to figure out what they could do.

"Why don't we try to stop the volcano from blowing up and maybe that might send us back."

"That is a brilliant idea Sho if you wanted us to get stuck here! Don't you listen to mom at all?"

"Why no because she hasn't started to teach me yet block head."

The fight was interrupted as one of the small babies tried to take off Sho's head. Rin frown and thought about it for a moment. And then something clicked.

"By Jove I think you have it Sho!" She said excitedly while taking his hand and suddenly there was that feeling of falling through time.

Both of them watched as their earlier counter parts time traveled back to the prehistoric era.

"So do you think they will notice?" Sho asked looking at the baby flying lizard that hitched a ride.

"Notice what?" Both mother and father asked looking at them.
