A.N. Fans of The Future is Wild support the CGXLuis pairing, but there has always been the problem that CG is from the 12000s and Luis, Emily and Ethan are from the 2000s. In this story I've solved that problem in the best way I could think of.
The Time Flyer crew had been searching for the proper new habitat for humanity from CG's time era for a long time (to them anyway), and finally the new location was settled: the Northern Forest of 200 million years AD. They had first gone to CG's time era to discuss this with CG's father and to restock on supplies. After debates and some problem solving, it was determined that that habitat would be the most stable out of all the other options, especially considering that it would last longer than the previous time eras they had visited. Instead of living in the forest however, it was decided that the human homes would be placed alongside the mountains surrounding the forest. This was due to not wanting to be really close to the megasquid, and not wanting to disturb the squibbons' habitat of the treetops (Emily especially was against this). After the whole matter had been resolved, CG's father left to inform the other officials and the crew decided to do one last tour of the other time eras.
"It's kinda sad that we won't get to see all those wonderful animals from before 200 million years anymore." Emily said sadly as the crew was on their way to Tropical Antarctica of 100 million years AD.
"That's not entirely true, we'll still have the Time Flyer and there are others back in my time era." CG corrected. "We just won't see the other animals as often as we used too."
"In cases like carakillers and lurkfish I'm not complaining." Ethan chuckled.
"Well, maybe, but we won't see babookaris, shagrats, or poogles again for a while either." Emily sighed.
"True." Ethan agreed.
"I am glad that CG's people will have a more stable home, but what I'm going to miss is all the traveling." Luis said. "After this tour that's it, the three of us will have to go home."
"Gee, that's right." Emily realized.
At that point, they arrived in Tropical Antarctica and landed in a bare spot in the forest.
"I am going to miss you guys." CG nodded sadly. "Even Ethan surprisingly."
"Thanks...hey!" Ethan protested.
"I'm kidding Ethan." CG chuckled.
The other three members of the crew were amazed, when they first met CG she was serious, even a little robotic. Now CG was as open and fun-loving as the rest of them, she sometimes even took options - mostly from Luis - rather than just ordering everyone.
"So, how are we going to explore?" CG asked.
"How about we split into two groups and each group take photos of specific animals?" Luis suggested.
"Sounds like an excellent plan." CG smiled, causing Luis to blush happily - no one noticed this.
"Ethan and Squibby and I can take photos of the falconfly and the roachcutter." Emily offered.
"Okay but we better lather up on the falconfly repellent." Ethan agreed. "I am not getting jabbed in the leg again like the first time."
"Of course we'll use the repellant." Emily chuckled, grabbing the repellant and a camera.
"Okay, Luis and I will take care of the spitfire inhabitants." CG said as she grabbed another camera.
The two groups left and went their separate ways. Ethan and Emily had lots of luck and didn't run into any danger, especially thanks to the repellant. After getting some photos of the spitfire beetles CG and Luis moved on to take photos of the spitfire birds, but they had some trouble at first. This changed when they stumbled onto a flock of spitfire birds, all in nests in the trees. Creeping quietly so as not to disturb the birds, CG and Luis got closer. Luis then snapped some photos, but unfortunately this agitated the birds and caused them to fly towards CG and Luis.
"Uh-oh." Luis said as he realized the situation.
"Run!" CG ordered.
She and Luis did, and continued running for a few minutes. Unfortunately, CG didn't notice a tree root and she tripped on it.
"CG!" Luis cried, skidding to a halt.
He then ran towards CG as the spitfire birds prepared to fire. Instead of getting CG however, they unintentionally got Luis! At the last second, he covered his eyes with his arm and jumped in the way so that the acid splashed onto his chest, cheek, arm, and half his forehead. CG screamed in horror as Luis fell to the ground in pain, his skin blistering and turning red.
"Strange, our acid seems to be really harming his shell." One spitfire beetle said.
CG and Luis of course couldn't understand them, actually CG wasn't even paying attention. She was too busy resting Luis head in her hand and worrying about him.
"Maybe he doesn't have a shell like those falconflies, maybe he has skin like us." Another spitfire bird suggested.
"With no feathers? Weird." A third spitfire bird shook his head. "Let's go I don't think they'll bother us anymore."
The spitfire birds flew away, but CG was too busy contacting Ethan and Emily to notice. After CG explained the situation, Ethan and Emily rushed over to help her get Luis back into the Time Flyer. Squibbon was swinging from the trees not far behind.
After Luis was brought into the back end of the Time Flyer where the sick bay was located, the other three tried to decide what to do.
"Cassiopeia?" A familiar voice called fro the pilot section.
"Father...you two figure out how to treat Luis I'd better let father know what happened." CG ordered, a bit agitated.
Ethan and Emily agreed, and decided that the first thing to do was to get Luis's shirt off him. The next step was harder, since they didn't know whether to peel away the harmed skin or not. Luis convinced them to peel away the skin, since he figured that he would heal faster that way. Then they soaked his skin water and spread ointment onto his wounds and bandaged them, which took a while since they were trying not to hurt Luis any further.
Meanwhile, CG told her father what happened. CG's father was concerned about Luis, but CG was miserable.
"He took the...it's my fault...I shouldn't have..." Too upset to speak, CG resorted to crying. "What kind of leader lets her crew get hurt?" She sobbed.
"CG, it wasn't your fault." Her father said gently. "From what you told me you didn't let Luis get hurt, he chose to get hit by that blast of acid."
Her father used to just call her Cassiopeia, but he too had been softened by CG's friendship with Luis, Emily and Ethan. He even became really close friends with Luis after their unintentional bonding moment when CG's father had to help Luis get a Toraton off the Time Flyer. Long story. Anyway, CG's father now only called her Cassiopeia during a serious moment and used CG for friendly moments or when he was comforting her.
"But he did it for me." CG tried to calm down so that she could talk.
"Which proves that you're a great leader." CG's father smiled. "A crew would only risk their safety for a great leader."
"Or a great friend." Emily added as she entered the front. "Any one of us would do what Luis did only for a great friend, leader or not."
"Still..." CG was ready to cry again.
"Come on Ceeg, you shouldn't beat yourself up about this." Ethan shook his head. "I mean you can feel sorry that he got hurt, but there's no reason to feel guilty."
"Take a few minutes to calm down Cassiopeia, then I want you and your crew to finish your tour and come home as soon as possible." CG's father ordered gently. "The officials would like to personally thank you and your crew for all your help and it's almost time for your crew to return to their home."
"Yes father." CG said sadly.
"Truthfully, we don't want to be separated from CG forever." Emily said. "She's our friend."
"I know, and I know that Cassiopeia doesn't want to leave you either, but you can't stay with us, it would disrupt the space-time continuum." CG's father said sympathetically. "Now, before I go I'll go thank Luis for saving Cassiopeia. Good-bye."
"Bye father." CG said, still sad.
"Bye." Emily and Ethan waved a little.
