At Thorndyke Mansion Garage Sonic, Tails, and Chuck were in the garage. Tails was holding the device Sonic was given. It was the same device Eggman was working on before his base was destroyed.

"This is the last part we need! All we have to do is put it in the machine and we're set!" Tails said.

"Let's test it out and make sure it works." Chuck said.

"Looks like we did it, Chuck!"

"With Eggman's help…" Sonic said.

At Thorndyke Mansion dark clouds were covering the skies while Tails and Amy headed to Chuck's car set to tow the Tornado 2. Ella, Cream, Cheese, and Vanilla headed to another car while Nelson and Lindsey waved from the house as the two cars drove away.

In Chuck's car Sonic was sitting on the wing of the Tornado 2.

At the Gateway Portal a giant portal had been set up in the middle of the bridge in Station Square. Its sole purpose was to get Sonic and her friends home. Knuckles was standing in front of this portal while Danny, Frances, and Helen were also there. Both cars arrived, and Amy, Cream, and Cheese hurried over to the kids.

"Goodbye, guys." Danny said.

"We'll miss you." Helen said.

"We wish you didn't have to go." Frances said.

"Time to see if this machine works." Chuck said and Tails nodded.

"Yeah." Tails said, pressed a button and a pair of revolving light at the portal's top activate.

The portal activated, but turned off a moment later.

"We don't have enough power, Tails." Chuck said.

"What'll we do? The other Emeralds are still missing!" Tails said.

"You could use one of these." Sonic said from her perch on the Tornado 2, held up the red Chaos Emerald she found in the mountains, rushed over and handed it to Tails.

"Great! We have enough power now!"

"All right, Tails, let's power up!" Chuck said and everyone looked on excitedly as the Chaos Emerald was inserted into the Gateway Portal.

"Here goes."

This time, the portal came to life, its bright light spreading across the city and blinding those close to it. All of the Mobian animals were sucked into the portal.

"I guess it won't be long before we're all back home, guys." Amy said and the Grand Egg Imperial was sucked into the portal.

"The pleasure was all yours!" Eggman said.

"Take care!" Bocoe said.

"It was nice attacking you!" Decoe said and the portal closed.

Then Amy dropped her suitcase in surprise.

"Hey! Why did it just shut off?" Amy asked.

"Chao!" Cheeses said.

"We can still go back home, can't we?" Cream asked.

Everyone was surprised and sad at the same time.

"There was a power burnout. We don't have enough energy now to send the rest of you back." Chuck said.

At Station Square people crosstalk.

At the White House the President facepalmed.

At the Gateway Portal.

"I'm not giving up yet!" Tails said, tried to fix the problem and Chuck was soon by his side.

"But Tails…" Chuck said.

"If I make some adjustments, I think I can draw even more power from the machine." Tails said and Chuck nodded.

"It's worth a try." Chuck said when Sam Speed pulled up in his car.

"Sam." Amy said but he drove away immediately, causing her to blink in surprise. "He didn't even get out of the car."

At Station Square.

"Maybe it's time for me to hang it up. There's not another competitor out there like Sonic. When he steps through that gate, I'll lose the greatest challenger I ever had." Sam said and had a flashback of the time when Sonic executed a sonic boom. "Good luck, Sonic... and thanks."

Back at the Gateway Portal.

"That was the fastest goodbye ever." Amy said.

"I think he just broke another world record." Ella said and she, Amy, and Cream shared a laugh.

"Chuck, I think it's fixed." Tails said.

"Let's give it a go." Chuck said and Tails nodded, pressed the button, and the portal came back to life.

Suddenly the ARK's Eclipse Cannon activated and struck the portal, intensifying the portal's power and causing Tails and Chuck to shield themselves from the bright light.

"That light…" Chuck said.

"It's from... Space Colony ARK!" Tails said and the portal was once again active. "Now we have all the power we need!"

"Excellent work, Tails!"

"You did great, buddy!" Sonic said.

"Thanks!" Tails said, they exchange a thumbs-ups while Chuck started to become teary and hugged him. "Chuck?"

"I'm going to miss you." Chuck said and Tails started to cry as well.

"Yeah. Goodbye, Chuck. ...You've been a great teacher... and an excellent friend, too." Tails said and Chuck's tears flow freely.

Helen put flower crowns on Cream and Cheese. She, Frances, and Danny were teary.

"We made this for you, Cream. We know how much you like flowers." Helen said.

"It looks great on you." Frances said.

"You like it?" Danny asked and Cream was teary as well.

"Thank you all! I love it! ...But not as much as I love all of you!" Cream said, hugged Helen, and the three human children started bawling.

Even Ella was crying.

"Don't cry, Ella, or you're gonna make me lose it, too." Amy said and Ella lifted the cactus that Amy gave her.

"Don't worry. I went to the plant store and bought myself a cactus to take care of. I named it Amy, after you." Ella said.

"That was sweet of you, Ella. Thanks. Thanks for taking care of us." Amy said and tears spring to her eyes too.

"You and Mr. Tanaka made us feel welcome." Amy said and Tanaka bowed.

"It was our pleasure. I wish... you could stay longer." Tanaka said.

"Here. This might help you remember me." Ella said, handed Amy a booklet and Amy opened it.

"You wrote down your favorite recipes so I can make them when I'm back home. Ella…!" Amy said, ran to Ella and hugged her. "Oh Ella, what'll I do without you?!"

"I don't know!"

"Hurry! We can't keep the gate open long! You have to leave immediately before there's a power failure!" Chuck said and Vanilla, Cream, and Cheese flew through the portal.

"Thank you for everything." Vanilla said.

"It was nice knowing you! Bye-bye!" Cream said.

"Chao chao!" Cheese said and Amy was next.

"Thank you all!" Amy said and Tanaka bowed as Tails flew the Tornado 2 through the portal.

"It's been a blast!" Tails said and Chuck saluted as the plane vanished into the portal.

Then Rouge handed Topaz a beautiful gem while Shadow watched.

"Take this before I change my mind. When I saw that gem in the jewelry store, I had to get it for you. It was a steal." Rouge said, pocketed the gem and started to shed her own tears. "See ya." she said, waved and let the portal take her back to Mobius followed by Shadow while Topaz cried openly.

A teary Tanaka put a hand on her shoulder while Knuckles and Sonic stepped toward the portal.

"Soon we'll be back home, Sonic... Back home." Knuckles said and Sonic smiled. "Let's go." he said, stepped, into the portal and Sonic nodded.

"Okay." Sonic said and stepped toward the portal.
