Guest and X: Thanks for the encouraging reviews. You know, every time I write I wonder if I'm doing a good job. I appreciate the feedback. Don't worry. I specialize in happy endings ;)

Mari. v: Gracias por tu comentario. No te preocupes. Me gustan los finales felices.

Last chapter. I hope you've enjoyed it. Shamelessfangirl, this is dedicated to you, wherever you are.

Disclaimer: I don't own Gen Rex or this idea. But I hope I did justice to both.

"It looks like it's here." Holiday said looking at the tracker.

"Of course it would be." Rex groaned. "They always hide in spooky abandoned warehouses."

"It's not abandoned." Six pointed out. Several workers were milling about.

"Yeah, you know what I mean." Rex replied. "It's like they have no imagination."

"Where should they hide?" Holiday asked amused.

"You know, at the mall, or someplace that has nachos. I could really go for some nachos." Rex's stomach decided to growl then.

Holiday smiled and unexpectedly gave him a hug. "Never change, Rex." She let go and walked into the warehouse.

Rex stood stunned for a second. He looked at Six who walked passed him.

"I disagree. There are some things you need to change… like your underwear." He said wryly.

Rex was stunned again. "Was that a joke?" He ran after them.

Once inside, they were confronted with a maze of crates.

"Here puppy, puppy. Here boy." Rex started whistling.

"Rex, what are you doing?" Six asked flatly.

"Calling for the dog." Rex said.

"We have a tracker." Six reminded him.

"But why wander around if it'll come to us?" Rex reasoned.

"That might not be a bad idea." Holiday concurred. "The tracker is not sensitive enough to pinpoint the exact location."

Rex turned to look at Six triumphantly. "See, I was right! In your face." Then at Six's glare, he added, "Sir."

Holiday pulled out some biscuits from her pocket. She placed them in the center of the room. She then backed away and hid behind some crates.

"Well, are you gentleman going to stand there looking pretty or you going to make yourself scarce?" Holiday asked.

Six and Rex quickly stepped behind some boxes as well. They waited.

"I hate waiting." Rex complained.

Both Six and Holiday shushed him.

There was silence.

Rex's stomach growled. Six glared at him. Rex shrugged. Holiday suddenly motioned for them to look. Sure enough a small shadow emerged. It sniffed around and spotted the biscuits. It hesitantly came out to the open, its hunger overriding its caution. The dog began nibbling at the food.

"Now!" Rex jumped out with his Smack Hands to try to catch it. The dog yelped and leapt out of the way. His Smack Hands embedded itself into the ground. It skidded past Rex. Six shot out in front. The dog stopped and tried to side step around Six. Six followed the dog's movements. Then he made the mistake of lunging for it. The dog slipped though his arms. In frustration, Six's blades slipped into his hands. Then he paused in mid swing when he saw Holiday wag a finger at him. She held the dog in her arms. It was happily eating another biscuit in her hand. Six straightened his tie and put his blades back up his sleeves.

"Great, we got it. Now what?" Rex asked as he reached out to pet the animal.

It growled at him and Rex snatched his hand back.

Before either of the adults could answer, there was a loud explosion. A bright ball of crackling energy appeared in the center of the warehouse.

"Rex, Agent Six? Can you hear me? It's Caesar." Caesar's voice echoed into their comlinks.

"Bro, what's going on?" Rex asked.

"Another rift has opened up. If Dr. Holiday has found the animal, they should both enter it and go home. Then everything should go back to normal."

Meaning back to life without her. Six thought grimly.

"Rex? Can you get my bike from outside?" Holiday asked.

"Sure, Doc." Rex left.

When Rex's back was turned, Rebecca with the dog firmly tucked under one arm wrapped the other around Six's neck.

"I'm sorry." She whispered softly.

"I'm not." She looked at him in surprise. "You gave me a chance that I never thought I would ever get. I got to hold you, to cook for you, to tell you…" He couldn't go on. Six took off his shades. Looking into her eyes, he gently held her face in both hands. Running his thumb over her lips, he lowered his head and kissed her. When the kiss ended, she smiled sadly at him.

"I love you." She told him.

Six nodded unable to speak.

"Thank you, for everything." She told him.

"Doc! I got your bike." Rex pushed in the old bike that brought Holiday to them.

"Thanks Rex." Holiday hugged Rex again. When she let go, she looked into his shocked face. "I'm glad to see what a fine young man you've become in this world. Take care of yourself… and I'm so proud of you."

Rex could only nod. He grabbed Holiday in a fierce hug. Letting go, he quickly swiped the back of his hands over his eyes. Holiday sniffed as she took the bike from Rex.

"Well, good-bye boys." She said as she got onto her bike. Taking the dog, she strapped it into the back carrier she had brought along. Holiday's face disappeared behind her helmet. She revved her bike. Giving a salute, she circled around in her bike before riding into the rift. As the light engulfed her, the rift shrunk and with a pop disappeared.

Rex and Six stood in the dark warehouse in silence. Six stared at the spot where the rift had been. After not moving for a long time, Rex walked over. He worriedly put his hand on Six's shoulder.

"You… uh… you okay, Six?" He asked.

"I'm fine." He answered brusquely. Then in a gentler tone, he added, "Let's go home."

To Rex's surprise, Six put a hand on his shoulder. They walked out together.

When they returned back to base, White wanted to see Six. Rex wandered back into the lab. It had been a strange few days. Seeing Holiday again brought back fond memories for Rex. He had no regrets like Six did. It had been nice to know that Holiday was proud of him. Despite the loss again, Rex felt strangely light. He hoped Six gained some closure as well. Walking into Caesar's lab, he stopped.

"Caesar?" Rex asked with concern. His brother stood rooted in one spot staring at some contraption on the floor.

"Rex, I'm afraid I may have made an error." Caesar said ruefully.

Rex raised an eyebrow.

Meanwhile after White had chewed him out for not informing him about the universe ripping itself apart, Six walked into Holiday's quarters. He sat on the bed and buried his head in his hands. He then raised his head and placed it on his folded hands. He stared at the closet. He would have to take her clothes back to storage before they cleaned it out. He got up. Touching the soft fabric lightly, he let his mind run back to the short time he spent with her. He would have to make those memories last his lifetime. He began gathering the clothes.

"Six!" Rex's voice was laced with panic.

"What is it?" Six put his finger on his comlink.

"Get to Caesar's Lab, quick!" Rex said.

Six dropped the clothes and sprinted to the lab. When he got there, he saw Caesar and Rex looking at the monitor. He raised a quizzical eyebrow.

"Caesar has something to tell you." Rex nudged his brother.

"Oh, yes, well after you asked me to look into… the matter, I was unable to finish studying all the data before another rift appeared." Caesar said looking uncomfortable. "But after studying the situation some more, I realize there might have been an error."

"What error?" Six asked slowly.

"Well, the universe is ripping and tearing itself apart but not so much because of Doctor Holiday. It's her universe that's dissolving. The Nanite Event in her world was much more violent than ours. The errant nanites are mutating the very fabric of their reality so that it's collapsing onto itself. It's causing a ripple effect in all the surrounding worlds. That explains all the rifts that have been appearing in our world. Their destruction is entering our world."

"And we sent her back to that?" Rex never heard his mentor's voice raised an octave higher.

"Wait, that's not the worse of it." Rex said.

"Because their universe is affecting ours we need to plug the leak, so to speak, before their destruction can destroy us." Caesar pointed to the contraption on the floor. "We need to open up a hole and send this into their world. It's a dimension sealer. It will emit an energy signal to keep their tachyon particles from entering ours."

"And we do this how?" Rex asked Caesar.

"We take a Scout Ship to a remote part in the desert. Open a rift to their world, place the dimension sealer and close the hole. That should stop the rifts from opening up in our world." Caesar explained.

"No." Six said. Both brothers looked at him.

"We don't do anything till after I find Holiday." He said firmly.

"But Six, it may be a matter of hours before the destruction of their universe. We don't…" Caesar began.

"NO!" Six roared taking everyone aback. "I will not leave Holiday to die… again. We find her first, place the sealer, and then leave… or so help me I will gut everyone here." He glared fiercely at the brothers.

"Okay" "Yeah, sure" "Since you put it that way…" Caesar and Rex both mumbled.

Then Rex put his hand on Six's shoulder, "Hey, I wouldn't leave Holiday either."

"I know, Rex. Let's go." Six patted Rex's hand.

"Why do we have to do this in the middle of the desert?" Rex complained.

Caesar turned on his dimensional disruptor, which was set on a tripod. I giant crackling ball of energy exploded in the distance. Rex was knocked off his feet by the backlash. "That's why." Caesar said flatly. "Agent Six, you have less than an hour to find Dr. Holiday before the hole closes trapping you both in the world. In the event you are trapped, make sure that you turn on the sealer before it destroys our world."

Rex glared at his brother. "Really, bro, that's harsh." He turned to Six. "Hey, you better come back. I still need you."

"I'll try my best." Six left the rest unsaid. Rex knew that if he couldn't find Holiday he wasn't coming back.

"You're going in blind again." Rex observed.

After a second, Six looked at Rex. "No, for the first time in my life… I see what I have to do."

Rex gaped at him in surprise. He was even more shocked when Six pulled him into a hug. Then letting go Six grabbed the sealer and entered the energy field…

… And emerged on the other side of chaos. The sky was a swirling red, reminiscent of Abysus. The desert itself was a flat dry wasteland. In the distance he could see the cities literally dissolving away.

He placed the sealer on the floor and pulled out the tracker Caesar had given him. Whipping out his hoverboard he followed the signal. According to Caesar, the world here was shrinking, so the amount of places Holiday could be would be limited. Sure enough the tracker picked up her signal after a few minutes. Six quickly followed the signal. He reached the outer edge of a crumbling city… literally. Facades of buildings were falling down on the streets below. Six had to swerve to avoid the debris, all the while keeping an eye on the blip on the screen.

It led him to a dilapidated apartment. Six flew through a window. Inside the apartment was empty. Strapping the hoverboard to his back, he kicked opened the front door to get out into the hallway. To his horror there were people outside in various stages of turning into EVOs. Six ignored them as ran down the stairs. Remembering what Holiday said about the tracker not being accurate, he began calling her name. There was no answer. All he heard was the sounds of people becoming EVOs. A tentacle wrapped around his ankle and yanked him to the ground. His blades slid from his sleeve. One swing and he was free. With his swords drawn, he carefully made his way through the corridor.

"Holiday!" He called carefully. A human-cat EVO burst through one of the apartment doors. It tried to pounce on Six. Crossing his blades, he caught the EVO in mid-air and using its own momentum threw him across the hallway. It skidded to a stop before charging him. Six stood ready. As the EVO leapt with claws drawn, it suddenly dropped to the ground.

"Holiday?" Six looked at the woman with the smoking tranquilizer gun.

"Six? What… What are you doing here?" Holiday's clothes were disheveled and her hair flew wildly out from her bun. There were dirt smudges across her face but to Six she was the most beautiful sight he had ever seen.

"I've come to bring you home." He was next to her in seconds. Grabbing her arm, he dragged her along.

"Wait, I… I can't go. I'll destroy your universe." She pulled away.

Six gripped her arms. "I can't explain everything right now. Do you trust me?"

"What?"

"Do you trust me?"

Holiday thought a moment. "Yes." She answered with head lowered.

"Then trust that I know what I'm doing." He lifted her chin so that their eyes met. "I'm not leaving you again. We go together or we die together."

Holiday gaped at him, but nodded. He gave her a quick kiss before pulling the hoverboard from his back. He got on and offered a hand to Holiday. She hesitated a second before taking his hand. He helped her up. Making sure she was securely holding onto him, Six sliced a hole in the building to escape.

All around them were sounds of destruction.

"What's going on?" Holiday asked Six as she saw the devastation.

"The nanites in your world are ripping your universe apart." Six answered.

A pterodactyl EVO swooped down. Six had to swerve to miss it. Holiday nearly lost her balance.

"Hold on!" Six cried. "Evasive maneuvers." He flew from side to side avoiding the EVO's attempts to bring them down. He flew straight at some electrical wires. Right before hitting them he pulled up. The EVO, who had no time to stop, slammed into them, electrocuting itself.

"Almost there." Six told Holiday who tightened her grip around his waist.

Soon she saw the glowing energy ball from a distance.

"Six, it's starting to close." Holiday shouted.

Indeed the glow seemed to be receding.

"Hang on!" Six sped up.

Just as they reached it, Holiday was pulled from the hoverboard.

"HOLIDAY!" Six bellowed as she fell to the ground.

"Six!" Her terrified voice spurred him on. Slipping a blade from his sleeve, he cut the vine around Holiday's waist. Then flying underneath, he neatly caught her. The owner of the tendril was not happy. From the dry ground a cactus EVO burst forth. Spikes shot from it's body while more vines grew to block their way. Six blocked each spike with his magna blades. Holiday scanned the EVO.

"There, that's the nerve center. Cut it off and the rest will die." Holiday pointed to the bulb sticking out of the side of the cactus.

Six nodded. He pulled some shurikens from inside his jacket. Letting them fly, each hit around the bulb. Ooze flowed from the cuts until it burst open. The vines immediately withered. Six moved quickly before anything else could happen. The world around them started waning. From the corner of his eyes, Six could see particles floating off the ground and dissipate into the air. Caesar was right; the world was dissolving. When they reached the rift, Six landed.

"Why are we stopping?" Holiday asked looking behind her.

"I have to turn this on." Six ran to Caesar's dimension sealer. He typed in the sequence and flipped the switch. The machine started humming. He took a few steps back before making a full 180 and dashed toward the slowly shrinking rift.

"Run!" He yelled to Holiday. Holiday turned and ran towards the closing gate. Six caught up and grabbed her hand pressing her to go faster. The rift seemed to be closing faster as it grew smaller. Six stopped and pulled Holiday into a kiss before swinging her around and catapulting her through the rift just as it closed. The last thing he saw was Holiday's stunned face. But she was safe. Six sat in the dust and waited for the nothingness to claim him. Despite the fact he was going to die, he felt a sense of peace that he hadn't felt in… ever. Holiday was safe and that was all that mattered. In the distance he could see the cloud approach him. A noise behind him made him turn around. A pair of Smack Hands appeared in the middle of the air.

"Come on, Six, let's go!" Rex said in a strained voice.

He needed no further invitation. Jumping to his feet he bounded through the tear, knocking into Rex. They both fell down in an undignified heap.

Six untangled himself from Rex and was knocked down by another body, who kissed him fiercely before punching him in the shoulder.

"Don't you ever do that to me again!" Holiday's face was tear stained.

"I don't plan to." Six assured her before putting both arms around her. She buried her face in his neck. Six looked up to see Rex grinning.

"Good job." Six told him.

"Eh, it was Doc's idea. She said that since I could communicate with the nanites I could probably get the nanites to open the gate a few more seconds." Rex nodded to Holiday.

Six tightened his hold on Holiday.

Caesar cleared his throat. "I hate to break up this… moment but I think we should all head back now. White Knight has been screaming in my ear for the last 20 minutes."

"Some things don't change. No matter what universe you're in." Holiday observed.

"And some things do." Six replied gripping her hand. "Let's go home."

20 years later

"Mommy, tell us the story about how the prince finds his lost princess and rescues her from the breaking world." The little girl asked her mother.

"I just told it to you last night, and the night before, and the night before that." The mother laughed.

"Please, mommy? We want to hear it again." Her sister added.

"No, no, it's time for bed." The mother insisted. "Come on."

The little girls groaned in disappointment.

"How about I tell it to you tomorrow?"

"Promise?"

"Promise. Good night, darlings."

"Good night mommy." The girls echoed.

She shut off the light and closed the door.

Six sans sunglasses was leaning against the wall with his hands in his pockets.

"I'm more of a knight in shining armor than a prince." Six smirked.

"Hmm, interesting, I've always pegged you as a… scary ninja with a heart of gold." Holiday walked into his arms and placed her head on his chest. His arms automatically enveloped her.

"But you are a princess, my princess." He murmured into her hair.

Holiday gave an amused snort. "Hardly, but thank you. Is the boy asleep?"

"Yes, finally. Took two glasses of water and a threat before he would go. Takes after Rex." Six complained.

"I'm sure Rex would be proud of that." She giggled.

They both stood in the hallway holding each other.

"I love you." Six said.

"I love you, too." Rebecca looked up at him. "It's late. Let's go to bed."

A sly glint came into his eyes. "We can do that… or…"

Rebecca laughed. "You're insatiable."

"Only with you." Six nuzzled her neck

"It better be." She threatened playfully. She took his hands and pulled him down the hall into their room. The door shut quietly and the click of the lock echoed through the hall.

Fin. Done. The end.

I know the last part is a reference to my Gen Next stories but I don't think Shamelessfangirl read any of that. I just thought it might be nice to imply that they live happily ever after (or as happily as anyone can). I also don't think this would be part of my universe or the original GR universe. It's definitely AU.

Hope you enjoyed it. I have been contacting various writers on this site asking them to please finish their stories or offering to finish it for them but not many have gotten back to me (and some have flatly said no, which is fine). Maybe you guys can encourage (NICELY) your favorite authors to finish their story or to contact me if they want to quit writing or need ideas. I must add that I DO NOT WRITE SLASHES OR LEMONS. Sorry, it's just not my thing.

If you like anyone's work please show support by leaving comments/favoring/following. Hope to hear from some of you.

God Bless.
