Virgil sat frozen behind the wheel still shocked at what he had just seen, Gordon looked behind him at their passengers and cleared his throat in his brother's direction.

"Umm Virgil?"

Virgil blinked hard. "What?"

"Our passengers? We should probably get them to safe ground, don't you think?"

"Oh, yeah. Sorry."

Sontag looked between the two boys sorrowfully, "we're so sorry for you guys losing that plane. We had no idea who we were working for."

Clarke nodded. "How can we make it up to you?"

Gordon smiled as Virgil plotted a course for their passengers' base, "it's not your fault. There was a bigger scheme going on here, and you're not to blame."

"Thank you for rescuing us, we would've died if you hadn't come down to get us. Sorry about your craft being destroyed."

Gordon felt his heart break again, "that's no one's fault either. I got too close, and he got defensive."

Virgil looked across at him, "we'll go back for her, I promise."

Back on Tracy Island, Scott was still fuming whilst Kayo was re-encrypting the island's commutation system, Grandma Tracy was trying to calm her eldest grandson down.

"Scott, this wasn't your fault, Gordon isn't injured."

"Thunderbird 4 has been destroyed Grandma, and I wasn't there to save him or it."

"Virgil was, son. Those two are like cheese and crackers."

Kayo smiled slightly at the analogy, "that's true. Okay, we have a new system up and running. Perhaps the Hood got hold of it when he was on the island that time."

Scott frowned, "you think so?"

"It's just a thought. I mean the Mechanic knows Brains, perhaps he knows the Hood too? It's just a theory."

Scott looked out at the sky, "I'm going after the TV21."

"What?" Grandma Tracy raised her eyebrows. "It's not worth it son."

"It belonged to dad, Grandma, which means it belongs to us. It won't take me long to catch up with it, the Mechanic's ship isn't fast."

Kayo bit her lip, "I don't like this Scott. I'm all for taking down the Mechanic like you, but this is dangerous. You saw what he did to Thunderbird 4, and 2 for that matter."

"Kayo, this is one of the only things we have leading us to dad. I can't let it get away," he sat down next to her and held her hands in his. "I have to do this."

"I agree with Kayo bro, you should wait until Virgil is back with Gordon and we discuss this."

Scott shook his head, "I can't wait, Alan, this is too important. The longer I wait, the further away the TV21 gets from us."

Virgil called in, interrupting the group, "pilots Sontag and Clarke have been dropped off. Just going to pick up Thunderbird 4 and we'll be on our way home."

"FAB," Scott crossed his arms as Virgil's hologram disappeared. "I'm going to take off now, I'll call John and ask where the Mechanic is heading."

"Please Scott, wait until tomorrow?" Grandma begged.

"I'm sorry, but this can't wait."

Kayo sighed, "don't jeopardise your life."

Scott kissed her cheek, "I won't." He ran to the lamps and turned away from the lounge.

Meanwhile, Virgil was lowering the grabs to retrieve Thunderbird 4 with Gordon's help, but his mind was distracted by the events of the day. He had almost lost a brother, failed a mission and now had lost his father's own plane. As he thought about it, tears came into his eyes and he thanked the stars Gordon wasn't in the cockpit with him at that moment.

"Line secure Virgil, pull her up but be careful."

Virgil cleared his throat, "not much more damage can be done to her Gordon. The module is open. Be careful with the wiring."

"FAB. Are you okay big guy? You sound, well, you don't sound yourself."

"I'm fine. Hurry this up, we want to start repairs as soon as possible don't we?"

"Alright. In two pieces she's not that easy to manoeuvre," Gordon tutted and prepared the module for a wounded Thunderbird 4 to slide into. "This is going to take a lot of work old girl, and it's all my fault." He winced as the first half came up to the surface and he pulled her in using the towline, the second half followed and he secured the ship as best he could. "Virgil, Thunderbird 4 is onboard, lock the module."

"FAB," Virgil fired the clamps and lifted the module back into Thunderbird 2. "Let's go home."

Gordon walked into the cockpit and rested his hand on Virgil's shoulder gently, "it's okay."

"I let you down, and I'm sorry. I should've fired something at the arms of that ship, then maybe Thunderbird 4 would've been okay."

Gordon sat down in the co-pilot seat, "it's fine Virgil."

Virgil sighed. "I'll never forgive myself."

Gordon leant on his elbow watching the water below them shimmering, "we'll get to work as soon as we land."

Thunderbird 2 landed and the two boys headed to the lounge where Alan, Kayo and Grandma were standing by Jeff's desk.

"Virgil, Gordon. Thank God you're okay," Grandma walked down to them and pulled them into hugs. "Oh Gordon, don't scare your grandma like that again."

Gordon smiled weakly, "I'm sorry, I wanted to get away but he got me."

Grandma stroked his head, "it's okay honey. Do you want anything to eat?"

"No, I'm good thank you."

Grandma smiled, "you call me if you change your mind."

Kayo wrapped her arms around Virgil in a hug, "are you okay?"

"Yes. Thanks, Kayo."

Alan hugged Gordon, "I thought I was going to lose you, brother."

"Never Ali. Virgil, shall we get going on Thunderbird 2?"

Virgil looked around, "yeah. First though, where's Scott?"

"He's gone off to find the Mechanic and bring back the TV21."

"What?" Virgil frowned. "Is he crazy?"

Kayo nodded. "We couldn't stop him."

Virgil rubbed Kayo's shoulder, "just keep an eye on him, we've got a ship to fix."
