So I was talking with a friend and depending on how things go, I might give Allison a sister.

"Yes! Yes!" The doctor bellowed. "Now to train her to be the perfect heir, once she's old enough I'll train in everything I know. I shall call her, Experiment 01."

"Sonic? Are you there?" Tails said.

Sonic didn't reply, he kept staring at the infant with a sullen face.

"Sonic, what are you waiting for?" Shadow whispered.

"We can't leave.." The hedgehog replied. "Shadow, we can't leave her here.." Sonic looked to Shadow silently begging the other to agree.

The ebony hedgehog looked back at the child now in the arms of the scientist who ordered his robots to take the small hedgehog to the nursery he built for the child.

Shadow sighed. "Fine. Only because it would be beneficial to have something that potentially powerful on our side in the long run."

"Or you're just a big softie." Sonic teased.

Shadow gave him a deadpan stare. "You're pushing your luck, hedgehog.."

"I take it back!"

"Hmph.." The other hummed as he crawled passed the blue blur.

"Sorry, Tails, change in plans. Can you lead us to the nursery?"

"Nursery?" The fox asked. Tails sat in the tornado at the edge of the complex, far away enough that Eggman's security wouldn't react to him. He was looking at the scanner he installed into the tornado, he could see Sonic and Shadow by their energy signatures and the immediate space around them. In his hands was a 'borrowed' blueprint of the facility. "Hmm, there's a room labeled 'under construction' here.. make 2 lefts and you should be there."

"Got it! Hear that, Shadow? Two lefts."

Shadow nodded in reply and continued on.

The two went on as quietly as they could so Eggman would not be alerted to their presence.

Once they reached the vent that lead to the nursery they could see the doctors attempt at making a room suitable for children. Half the room was painted pink while the other half was blue. Most likely because the scientist had no idea what the gender of the child would've been at the time. Orbot was reading a magazine in the corner while Cubot rocked the crying infant.

"Rock a bye, hedgehog on the treetops..uhhhh... This isn't working!" The robot called out.

Orbot looked up from his reading."Try rocking her more gently. " He sighed.

"Oh!" The henchman tried rocking the baby slowly but it only resulted in more fussing and sobs coming from the little girl.

The spherical robot shook his head. "We're not nannies, put her in the crib for now. We, or more importantly you need some sort of child care software. "

"Roger!" Cubot placed the crying baby in the crib and the two robots exited the room.

Sonic's heart dropped, how could they leave a crying baby unattended? Although Shadow may have had a tough exterior he knew well enough to never leave an infant alone. The none to gentle rocking, the awful singing and complete disregard for her well being? All abuse in his book. And the worst part? She wasn't even an hour old!

After making sure the coast was clear the two hedgehogs vacated the ventilation system.

"Dang, it feels good to stretch!" Sonic said, being cooped up in a vent for nearly an hour is hard on the back and legs.

Shadow placed his hand over Sonic's mouth and told him to shush. Sonic nodded and walked over to the crib. The black and blue hedgehog looked back at him with bright ruby eyes, they were identical to Shadow's. The hero picked her up gently and slowly but surely the sobbing subsided.

"So, the doctor created this being from our DNA?" Shadow asked inspecting the child. He held out his hand to her and she gripped one his fingers. The ebony hedgehog's eyes almost widened at her strength.

"Yeah.. so, I guess she's our daughter in a way." Sonic awkwardly chuckled.

"It would seem so. " Shadow said with the faintest hint of a smile on his face.

Sonic was taken aback for a moment. Did Shadow just agree to parent this child with him?

Whatever moment that was there was cut off by approaching voices. The robots were coming back with the doctor in tow. The infant seemed to snuggle up closer to Sonic, even though they just met she already trusted him more than Eggman and his goons.

"Sonic, we can't bring her into the vents!"

"Uhmm..." Sonic thought aloud. "Tails, how far are we from the outside?" He asked quickly.

"Let's see.. um..oh! The nursery is right next to the outside! You need to bust down the wall!" The fox said.

Sonic and quickly placed the child back in the crib, can't have her getting hurt now. She gave him a frown that seemed to threaten more sobbing.

"It's ok." Sonic reassured. "We're not going anywhere without you!"

That seemed to be enough for the infant who gave him a tiny smile.

"So we're knocking down the wall?" Shadow asked crossing his arms.

"Yeah, on the count of three." The two got into position several feet away from the wall. "Three.. two...one..go!"

The hedgehogs curled up into spheres and built up speed until taking off at the wall full force. The wall gave way, crumbling at the brute force of the attack.

They could hear the doctor yelling and the footsteps coming faster. Shadow quickly got the baby from the crib and went out with Sonic into the wilderness.

Now carrying precious cargo, the two carefully treaded around the perimeter avoiding Eggman's security measures until making it back to Tails's location.

Meanwhile back in the nursery, Eggman was throwing a fit. Blaming his henchbots for the prisoners escape and the kidnapping of his heir.

"Ughhh" He sighed. "Do we have anymore of their DNA to create a new one?" The doctor asked rubbing his temples.

"I'm afraid not, sir." Orbot said.

"Perfect, just perfect!" The scientist said crossing his arms.

"Doctor! Doctor!" Cubot yelled. He came into the room quickly holding a cellphone.

"What now!?"

"It's your sister, sir!"

The scientist's eyes widened passed his glasses. He took the phone and listened to the voicemail left by his sister. The doctor began to chuckle which then turned to a roaring laugh.

"I may well have an heir yet!

Oh boy.. I wonder what that phone call is about? ewe
