There's three of them?

Showdown in Space

"The Master Emerald! I can use it to shut off the power." he said and stood before the others.

"There's still time to stop the space colony from crashing, but we have to hurry. We'll only reach the Chaos Emeralds if we all work together." Tails said.

"I'll lead the way. Stay on my heels and do your best to keep up the pace." Shadow said.

"Let's get to those Chaos Emeralds before it's too late." Eggman said.

Knuckles, Shadow, Eggman, Tails, Sonic, Bocoe, and Decoe took off to find the Chaos Emeralds.

"Remember: if we fail, then our entire planet will perish, and so will we." Eggman said.

Decoe and Bocoe were carrying the Master Emerald.

As they enter another room, laser turrets begin to fire at them. Tails flies through the lasers while Eggman and Sonic destroy a few turrets.

Tails reaches a lever and pushed it up with all his might, opening a door. Muddy water begins to cascade down upon Shadow, Knuckles, Bocoe, and Decoe. Knuckles punched a hole in the wall to serve as an anchor while the others hold on to his other hand. The flow passes by, and the group race through the door before it closes.

At the viewport.

"I hope they make it in time." Amy said.

"I wish there was something we could do to help Shadow and the others." Chris said and Tanaka lay his hand on Chris' shoulder.

"Shadow will get to the Chaos Emeralds in time." he said.

"Don't bet on it." someone said.

Just then Shadow entered the room.

"Silver!" Chris said and Shadow smirked.

Silver looked out the viewport as the station continues its descent. Chris braces himself and heads towards Silver.

"Master Chris..." Tanaka said but Chris ignored him.

"Please, Silver. You can help save us all." Chris said surprising everyone even Silver. "You believe that your whole reason for being here is to get revenge. But think about it." he said and took another step forward. "When I was in danger back on Prison Island, you decided to save me." he said the put his hand on Silver's shoulder. "Deep down, you know you were made to help others, and that's the reason you finally rescued me!"

"Hands off." Silver said and used his inhibitor rings to shock him, blasting him onto the floor some distance away.

"No! Chris!" Amy said and started forward, but Tanaka grabbed her arm. "He needs help." she said but he shook his head and Chris struggled to stand up.

"It's useless. I made a promise to Maria, and I'm keeping it." Silver said and Chris started toward him again.

"Silver, getting revenge won't bring Maria back." Chris said.

"So what?"

"There's still time to stop this, Silver. Please, you have to listen to me!" Chris said and started shaking Silver. "How can you blame people alive today for something that happened fifty years ago? Can't you see it's not fair?!"

"Don't talk to me about fair! Not after what happened here!"

In a flashback Silver, Shadow, Sonic and Maria were looking at Earth together.

"Maria was me and two other people's only friend, but your rulers sent soldiers to take her away from us. We tried to save her, but there were too many for us to stop." Silver narrated. "I never saw poor Maria again. Maria wasn't a threat to anyone. All she wanted was to visit your planet, but she never had the chance."
