The next day, everybody was ready (And Rouge was having fun with the register)

"Big Blue?"

"Rouge..."

"Fox Boy?"

"HEY!"

"Hot-Head?"

"WHAT?!"

Knuckles snatched the paper out of her hands, and asked;

"Bat-Girl Rip-Off?"

Tails laughed while Knuckles ducked Rouge's pick-nails, which had been thrown at him by said annoyed bat. Sonic sighed. If things kept going like this, they wouldn't get to Prison Island until next year. He cleared his throat and they all looked in his direction.

"Are we going to go now? We don't have all the time in the world, you know!"

Tails nodded while Knuckles and Rouge just gave an "Hmph!" The four of them then proceeded to Tails' workshop, where the X-Tornado was waiting for them. (A/N: Don't worry! This is the only Sonic X reference here!)

"Everybody ready?" Tails asked, with everybody else clinging to the wings of the plane.

"Yep."

"Ready."

"Of course."

The plane slowly began to make its way down the runway. It began to pick up speed, before finally lifting off the ground and into the sky. Sonic looked into the pale blue sky and once it was safe too, he loosened his grip on the wings, as did the others. He rolled onto his back and tried to relax, but it was impossible. His mind was clouded with worry. He knew perfectly well that they had only one shot at breaking his son out of that place. It was then something else crossed his mind. What if he didn't remember him? What if G.U.N had erased Shadow's memory? Sonic swore that if they had erased his memory, or indeed hurt him in any way, he would destroy G.U.N personally. Then he remembered that Gerald had designed Shadow so that it would be impossible to erase his mind. Unless GUN found some way around that. Knuckles saw the look that Sonic had on his face.

"You Ok, Sonic?"

Sonic rolled his eyes.

"Knuckles, We're about to break into a top-secret government base to rescue his long, lost son. He's not worried one bit." Rouge answered for him, in a VERY sarcastic tone.

"Sorreeeee..."

Silence ensued for a few moments.

"One question, do you think Shadow will even remember Sonic?" (Knuckles doesn't know all the details about Shadow's creation)

"What do you mean?" Rouge asked, raising an eyebrow.

"Well think, we could release Shadow and something like this could happen: 'Oh yes we're the sonic team and that blue guy over there, he's your dad', and then he has a mental breakdown."

"KNUCKLEHEAD, SHUT IT!" Sonic and Rouge both yelled at the same time.

"But-"

Rouge decided to play her new trump card. She got out a piece of the Master Emerald that she had found, and dangled it over the edge of the plane. Knuckles' eyes went wide.

"Ok Hot-Head, here's the deal: you don't do anything to annoy or upset any of us, or this little piece of your precious emerald meets the bottom of the sea, alright?"

Knuckles glared at her, then sat down and started to pout.

About an hour later, Prison Island came into view.

"Alright, I've equipped the X-Tornado with a special cloaking device that makes it invisible to both G.U.N's and Eggman's radars. Unfortunately, it only works on mechanical objects." Tails explained, as the plane landed on the island. He then handed three wrist communicators to each of them. "Use these to contact me when you need to." The others nodded, then ran off. Little did they know that they were not the only ones currently after Shadow...

Aboard the Egg Carrier III...

Dr. Ivo Robotnik, AKA Dr. Eggman had his sights set on the island.

"Project Shadow...I still can't believe that the ultimate weapon of destruction is related to that blue pest...nevertheless, it shall still be mine! MUAHAHAHAHA!"

Meanwhile...

The others had located a high security back-door.

"How come they always seem to have back doors?" Knuckles asked. Sonic shrugged.

"Who cares? Rouge, it's all yours. Sonic replied.

Rouge stepped up to the terminal beside the door and plugged something into it. After a minute, she said;

"Alright, we're in. I've managed to deactivate all security systems up to level three." They were about to continue through the now-open door when Tails' voice came in over the communicators.

"Alright, I've located Shadow. He's in the centre of level 5. Good luck."

The others then proceeded through the door. Due to the disabled security systems, they were easily able to make it up to level 4. As they entered lv.4, Knuckles opened an air vent and they all crawled in.

"My lord, it reeks in here!" Sonic complained as they crawled through.

"Sorry." Knuckles grinned sheepishly. Sonic and Rouge paused to give him disgusted looks, before crawling on, eventually reaching the exit.

"Wonder why there weren't any lasers in that air vent?" Sonic asked.

"Because this place was designed to be resistant against humans, not mobians, and the average human wouldn't be able to fit through that tiny vent, so they obviously didn't bother." Rouge answered for him.

"Humans can be idiots." Sonic muttered. Knuckles was about to answer 'so can you' before remembering Rouge's earlier threat. Sonic lifted his communicator to his mouth.

"Tails, how much further?" he asked.

"Well, that air vent took you through most of level 4, so after you drop down, keep going until you reach another security door. That'll take you to level 5 and it's straight on from there." Quickly and noiselessly, they dropped through the whole onto the floor. Grabbing onto Rouge and Knuckles, Sonic sped off until they reached the door. Rouge got out her hacking device again and plugged it into the terminal next to the door. Within seconds, the door was hacked and open.

"You know, for a top-secret base, the security is a complete joke." Rouge complained, as they made their way up the corridor, making sure to avoid any cameras along the way. They eventually came up to another security door, but no terminal was in sight.

"Great, so how are we going to open this without alerting the whole bas that we're here?" Knuckles asked.

"You sure this is the only way, Tails?" Sonic asked into his communicator.

"Positive." Tails replied.

Sonic was then struck by an idea. He took the hands of both his comrades and began to vibrate quickly, before going RIGHT THROUGH THE DOOR. Once they reached the other side, Knuckles asked;

"Ok, What did you do?!"

"Simple, I vibrated our molecules at such a speed that we went right through the door. In other words, we vibrated through it."

"You spend too much time around Tails." Knuckles said weakly. They were now in a very small room. A capsule was placed right in the centre. They ran up to it and peered into it, and Sonic could see his son's face for the first time in 50 years.

There was a small keypad on the capsule. Rouge tried every password she new, including the password to her own computer out of sheer desperation, before Sonic told her to stand aside. He then typed his own password in. M-A-R-I-A. As expected, the capsule opened. The seven-year-old hedgie slowly opened his eyes, trying to make out the three blurry figures above him, before recognising the middle one.

"Daddy!" he said happily. Overwhelmed by happiness, Sonic picked up his son and hugged him.

"Yes Shadow, it's me." Sonic said, tears of happiness in his eyes.

Then the wall collapsed.
