Disclaimer: I don't own the Lab Rats

I just wanted to make this fanfic to show what would have happened if the scene with Marcus and Leo went differently.

Douglas smiled and looked at his monitor that kept an eye on the secret entrance.

"Well, look who came and decided to play hero." He laughed as he sat at the keyboard. "This one's not even bionic, I could take him out with the sprinklers!"

"Leave him alone, he's just a kid!" Mr. Davenport said in fear for his youngest child.

"A nosey kid who keeps getting in our way." Douglas retorted.

"Stay away from him!" Bree shouted, gravely concerned for her youngest brother's safety. Adam and Chase too dumbstruck to do anything.

"Don't worry princess, I'm not going to hurt him." He paused for a moment before typing a small code into the computer. "Marcus wanted that privilege all to himself."

Suddenly the door to Marcus's pod opened with a hiss, and the android slowly walked out.

"Your friend, Leo's here. Take care of him." Douglas ordered his creation.

Marcus turned to face the four Davenport's in the cage, a sick grin crawling across his face. "Done."

"Don't you touch him!" Adam shouted as he strained as close to the lasers as was safe. "You sick excuse of an android; or I'll..."

"Or you'll what!" Marcus challenged, getting as close to Adam's face as he could. "You don't have your bionics, you can't do anything to me. I'm going to make Leo scream; and you're going to watch, because you are powerless to stop me." He taunted.

Chase and Bree could practically feel the anger radiating off of Adam as Marcus walked to destroy their baby brother.

"There has to be a trigger mechanism to make the hidden entry way appear." Leo said out loud to himself; feeling the wall, where he knew the secret entrance must be.

"Why don't you try banging your little wagon up against it!" Eddie teased.

"Enough with the wagon!" Leo shouted to the cyber butler, that was currently on his wrist. Little did they know that Marcus was standing behind them.

"Hello Leo."

"AHHH!" Leo screamed as he turned to face Marcus.

"Sorry you came all this way, but we're kinda busy; and frankly I've had it with you." The android snarled.

Leo quickly reached into his bag and pulled out one of Mr. Davenport's weapons. "Well, I've got this!" He exclaimed, pointing the gun like contraption at the android.

Marcus used his telekinesis to throw the device away. "No; you HAD that." He corrected.

"Oh yeah! Well, I've still got all of these!" Leo said proudly, gesturing to the bag filled with weapons.

The android snorted, and then used his laser vision to vaporize the remaining weapons, along with the wagon.

"No!" Leo exclaimed as he frantically looked for the weapons; silently praying for them to reappear.

"Goodbye's are tough, so I'll make this easy." Marcus explained as a ball of energy built up in his palm. His arm suddenly burst forewords as he shot Leo in the chest. The small boy was launched backwards by the sheer force of the blast.

"NO!"

"LEO!"

The Davenports screamed for their youngest as they watched him fly into the bushes from the blast.

They continued to watch in horror as Marcus picked up Leo's limp body and throw it over his shoulder, as he headed back inside.

Marcus walked back into the lab, Leo in tote, with a triumphant grin on his face.

"Man, am I glad I don't have to deal with him anymore." He said sickly, throwing the limp boy near the cage that his family was held in. "And to think, that he was the only one who ever figured out what I really am."

Bree put a hand over her mouth and threw herself into her fathers' arms; tears rushing down her face. He held her close to his chest as she shook violently with silent sobs.

"Poor Leo!" Bree wailed. "He tried to save us."

Chase took in a shaky breath as he turned away from his little brothers unmoving form, his tears dripping onto the concrete floor. "He tried to warn us about Marcus." He took in a shallow breath. "And we ignored him."

Adam stood frozen, a pained look on his face, and tears spilling from his eyes as he looked at Leo's body sprawled out on the floor. He then knelt where he was and looked at the ground. "God no, not him, not him..." He looked back to his baby brothers still body, not even a foot away.

"LEO!" Adam screamed with gut wrenching sadness.
