Author's note: Please note that I wrote this before "Sink or Swim" aired, so my description of the Triton App isn't quite like what we saw there.

I want to say that I appreciate all reviews, even the ones that just say "please update soon!" But I have been truly blown away by how many kind, intelligent, and thoughtful reviews I have received. You guys are the best. :)

To my guest reviewer Razara, thank you for leaving such kind reviews, even though the story didn't go quite the way you had hoped.

Several readers have expressed a little disappointment that Chase didn't fully go over to Douglas's side. When I first started this fic, that was actually my intention. But ultimately, I felt it would have been too out of character for Chase. I think he gets over-confident in his abilities sometimes and gets into situations he can't really handle. But he's not stupid. If it weren't for the events of "Bionic Showdown," things might have gone differently. But Chase saw what Douglas was then. I just couldn't have him ignore the fact that Douglas kidnapped them and tried to kill them and all that.

Whew! That was a long note. Let's get to the next chapter now. I may be out for a few days, as I need to write the ending to this thing and work on a tag I started last week. So please, no more death threats if I don't update? Pretty please? :)

CHAPTER FIVE- The Attack

Super-speeding across the Southern California desert for the first time should have been an exhilarating experience for Chase. Instead, it was like hurtling towards his doom at five hundred miles per hour with no way to put on the brakes. What had been a forty-five minute drive took less than five with his new ability. Almost before he knew it, Chase was standing outside the door to the Davenport mansion.

It was eerie and terrifying, watching his own body do things that he was not telling it to do. Douglas's Triton ap did not have quite the effect that he thought it would when he designed it. Although the ap easily took over Chase's body, it could not control his entire mind. There was a small part of him that knew everything that was going on and was desperate, but unable, to stop it. "Chase," and all of the things that made him who he was, still existed. But "Chase" had been pushed to the back of his own mind. He was merely an observer, watching through his own eyes as he walked inside and greeted his siblings.

"Hey, guys. Ready to train?"

It was remarkable, how normal his voice sounded. Even though he felt like a robot, his voice and actions and mannerisms were all so smooth, so exactly like he normally acted.

"Where have you been?" Bree asked. "We couldn't find you after school."

"Yeah," Adam agreed. "I wasn't going to leave you this time, but Bree made me."

"I got a ride from a friend."

"You weren't in your last class," Bree continued.

"Special project for the science fair." Where is this coming from? Not only could Douglas control his actions, he could make him lie, too.

Bree still looked suspicious, so Chase quickly changed the subject. "Can we get down to the lab? Mr. Davenport asked me to run a virus scan before we start training."

The lie, spoken from his own mouth without his consent, worked like a charm. Bree walked to the elevator without any further argument. And Adam followed after shoving the last bit of a peanut butter sandwich in his mouth and swishing it down with a large swallow of milk.

And "Chase" followed them.

Douglas must have been watching us for a long time. Somehow he had known that Mr. Davenport often asked Chase to run virus scans or perform system updates on his siblings. It was a request that Adam and Bree would not question. They immediately entered their capsules and waited as he started punching commands into the instrument panel.

The USB drive appeared at the end of his finger. Chase plugged himself into the panel, and the Triton program uploaded itself into Mr. Davenport's system.

From deep inside himself, Chase watched as his fingers typed in the command to send the Triton program into Adam and Bree's chips. He tried focusing all his remaining energy and everything that was left of himself on making his body stop. And for a second, his fingers hesitated. His hand hovered over the control panel, uncertain.

At that same moment, the lab doors slid open and Mr. Davenport walked in. "Hey, guys," he said cheerfully.

The momentary interruption broke his concentration, giving total control back to Douglas. Chase saw his finger press "enter." The Triton program began uploading into Adam and Bree.

"What are you doing, Chase?" Donald asked.

"Virus scan," he replied, not looking up.

"Really?" Donald joined him at the instrument panel. He frowned as he looked at the display. "That doesn't look like a virus scan."

"It is." The upload was 20% complete.

"Chase, I appreciate your initiative, but I don't like you uploading programs that I haven't looked at yet. Shut it down, OK?"

"No." 30% complete.

Donald looked surprised. "What?"

"Just give it a few more minutes. I already told you, it's a virus scan," Chase replied tensely.

"Chase, shut it down. Now."

"NO!" Chase shouted, startling Donald and causing his siblings to look up from inside their capsules in surprise.

45% complete.

Donald reached over and tried to shut the upload down himself. Chase angrily shoved him away from the panel.

"Chase, what has gotten into you?" Donald approached him again, more cautiously this time. He reached for the panel.

With an angry yell, Chase shoved Donald backwards again. This time, his super-strength kicked in. Donald went flying across the room and crashed into the lab doors.

From inside his mind, the real Chase screamed silently. Mr. Davenport!

He felt his body calmly turn back to the upload. 65% complete. Just another minute or two…

Adam and Bree were both pounding at their capsule doors, trying to get out. But the doors locked automatically whenever a program was running. Adam finally punched the door, shattering it and sending a spray of glass pieces to the floor.

Adam grabbed his brother around the waist, from the side, and dragged him away from the panel. Chase responded angrily by swinging around, taking Adam with him. The two fell to the floor and struggled until Chase was able to break free. Adam was still on the ground, staring up at his younger brother in confusion. Chase grabbed Adam by the arm and pulled him to his feet, then threw him across the room.

During their scuffle, Donald had managed to get to his feet and stumble to the control panel. Chase turned around just in time to see him hit the button that would abort the upload.

"Program is 90% complete," the computer chirped. "Are you sure you want to abort?"

Donald hit the button again.

"Upload aborted."

"No!" Chase yelled again. "You ruined it! You ruin everything!"

Adam had gotten to his feet, and Mr. Davenport was staring at Chase. Chase tried again to resist the force that was controlling him from afar, and for just a second, he felt his body hesitate. But the Triton program was too much. He felt his feet moving beneath him. He super-speeded out the door and back to Douglas's lair.

Bree finally managed to get her capsule door open. She joined her shocked brother and father on the floor. "Did you see that? Did he just…and then he…" She turned and raced out of the lab and outside to see if she could find him. Bree looked all around the house and off into the distance in every direction, but Chase was already gone. She rejoined her family in the lab.

"Mr. Davenport, how was Chase able to run that fast?"

"And how was he able to throw me across the room?" Adam added.

"I don't know, guys. But I have a pretty good guess." Donald hit a few buttons on the instrument panel, trying to bring up the program Chase had been trying to upload.

The lab doors burst open and everyone looked up, expecting to see Chase again. Instead, Leo burst in to the room, out of breath.

"Big D! Look, I know maybe I shouldn't tell you this and I don't want to go behind his back or anything, but I think something may be going on with Chase."

Bree glared at him. "Ya think? Great timing, Leo. Maybe you could have told us that five minutes ago?"

"Why? What happened?" Leo looked around, finally noticing the broken capsule door.

Donald looked up from the panel. "What made you think something was going on with Chase, Leo?"

"Well, he seemed really distracted today at school. And then, after lunch, I saw him get into a car with someone and leave."

Donald's eyes widened. "And you thought it would be a good idea to wait until NOW to tell me?!"

"I tried to call! But Principal Perry saw me using my phone and took it away. Then she gave me detention for having a phone in school. I just got home!"

Donald shook his head. He had warned his kids about not getting in cars with strangers since before they were old enough to know what cars and strangers were.

"OK, what kind of car was it?"

"I don't know," Leo replied. "Just a basic, dark-colored four-door. I only saw the side of it."

"Could you see the driver?"

Leo thought for a moment. He tried to visualize those few seconds of time. He had been so focused on Chase that he didn't take in much else.

"No, Big D. It was too far away."

"Could it have been Douglas?" Donald asked.

All three of the teens looked at him in surprise.

"Douglas? What makes you say that?" Bree asked.

"Well, I sure didn't give Chase those abilities," Donald replied. "And this program he was trying to upload; I think it was Douglas's Triton Ap. I recognize some of the code."

Leo looked confused, Adam looked sad, and Bree looked angry. "So he's working for Douglas now," she said angrily.

"Maybe not," Adam said quickly. "Maybe Douglas forced him to do it somehow."

"Leo, did it look like Chase got in the car willingly, or was he forced in?" Donald asked.

"He opened the door, set his backpack in the floor, and got in," Leo replied.

"His backpack…" Bree mumbled. She looked over to the corner of the room where Chase always put his books down when he came home from school. Sure enough, the backpack was there.

"Maybe there is something in here that will tell us what he was up to," she explained. She hurriedly dug through the contents. Books, papers, folders, pencils. When she lifted out one of the books, a small slip of paper fluttered to the floor. She grabbed it and held it up.

"It's a phone number!"

The others gathered around behind her to look at it.

"That's Douglas's handwriting," Donald said quietly.

"Are you sure?" Bree asked.

"We grew up together, and we worked together for years. I'm sure."

Adam took the backpack and reached into the side pocket where Chase always kept his phone. Sure enough, it was still there. He unlocked it and brought up the recent call list.

"He called that number yesterday."

"So he did contact Douglas himself. Which means he betrayed us," Bree said coolly.

The others looked at her in surprise. "How can you say that?" Adam asked sadly.

"What other explanation could there be, Adam?"

"There could be lots of explanations, Bree!"

"Like what?"

"Like, um…" Adam scrunched up his face, trying to think of something that made sense and would excuse Chase's actions.

"Like maybe he was upset about the fight you all had," Leo interjected. "Maybe he was feeling left out and unappreciated because you two were always trying to show him up."

"How would you know, Leo?" Bree asked, her voice rising in anger.

"Oh gee, I don't know. Maybe he talked to me because his other siblings wouldn't speak to him for three days," Leo said, his tone and pitch matching Bree's.

"That still isn't a reason for him to betray us!"

"GUYS!" Donald shouted, silencing the teens. "It DOESN'T MATTER why he did it. We can work all that out later. Right now, we need to focus on finding him before…before Douglas…" His voice trailed off, not wanting to verbalize what he was thinking.

Three sets of eyes looked at him nervously.

"Before Douglas what?" Adam asked timidly.

Donald sighed. "Before Douglas makes him do something terrible."

Douglas used his commands to guide Chase back to the lab and directly into a capsule he had set up in advance. Once Chase was locked inside, Douglas disengaged the Triton ap. Chase felt himself return to the forefront of his own mind, and control of his body was returned to him.

From outside the capsule, Douglas glared at him. "You failed."

Though he was still recovering and processing what had just happened, Chase did his best to glare back at his uncle. "Don't you mean 'you' failed? You were the one doing that. Not me!"

"Back there, in Donald's lab, your body didn't respond as quickly as it should have. You were resisting me."

Chase narrowed his eyes. "I will NEVER stop resisting you, no matter WHAT you do to me."

"We'll see about that. I'm going to have to re-work the Triton ap so that it takes total control of your entire mind and body. It's a complicated program, which means I have a lot of work to do. In the meantime…" He stood directly in front of the capsule and leaned in until he was eye to eye with Chase, separated only by the see-through wall.

"You're going to be in there for a while."
