Fast-Dash

Isaac is in an old research facility. He looks around.

The Reverse-Dash sped in front of him.
He removed his cowl.

"Hello, Isaac." Said Gertrax

"What do you want?" Asked Isaac

He showed him the parts he stole from Gladiator Corps.

"I need you to build a time machine."
Said Gertrax

"Not happening." Said Isaac

Gertrax pulled out a picture of Macy. Isaac changed his expression.

"If you wish to leave here alive so you can marry Macy, you'll do what I ask." Said Gertrax

At Gladiator Corps, Donnie is with Commander Morris. Macy approached them.

"Have you two heard from Isaac?"
Asked Macy

"No, why?" Asked Donnie

"He's not answering his phone."
Said Macy

"He must've been tired."
Said Commander Morris

"Or something happened to him."
Said Donnie

Donnie got up and sped off.

Gertrax is standing on a building.
Donnie halted. Gertrax smiled.

"Knew you'd find me." Gertrax said as he turned around.

"Where's Isaac?" Asked Donnie

"He's safe." Said Gertrax

"Why are you doing this?"
Asked Donnie

"Because you're predictable. Always saving the day. You're your father's son."
Said Gertrax

"Why'd you take Isaac?" Asked Donnie

"I knew you weren't gonna help me get home. So I took Isaac. He's building a time machine for me." Said Getrax

"Once he's done that, then what?"
Asked Donnie

"I'll go back to my time. I promise that I'll never return here again."
Said Gertrax

"How do I know that you'll keep your promise?" Asked Donnie

"You don't." Gertrax said with a smile.

Gertrax sped off.

Minutes later...

At Gladiator Corps, Donnie told everyone what Gertrax told him.

"Isaac's doing what?"
Asked Macy

"He's building a time machine for Gertrax." Said Donnie

"Why would he do that?"
Asked Commander Morris

"Gertrax lost his speed when he was fighting future-me."
Said Donnie

"What about Isaac?" Asked Lauren

"He'll let Isaac go." Said Donnie

Donnie left.

At his mom and dad's house...

He told them about the Reverse-Dash.

"So Gertrax wants Isaac to build a time machine so that he can return home to the 24th century?" Asked Jared

"Yes." Said Donnie

"And you're gonna let him go?"
Asked Kathy

"He said he won't come back to this time." Said Donnie

"Donnie, not everyone keeps their promises." Said Kathy

"I know, but as long as Isaac is safe."
Said Donnie
