[Authors note : This chapter is a little shorter than the others TvT I do apologize for that. But I didn't want to cram extra story into it so a short final chapter is the end product!]

After Spade gave Shadow and I our emerald, we decided to leave the city. We headed on our way back to where I first landed. It was the most preferable option because, as Shadow said when I first arrived, when you travel through time, you always land in the same place you left.
We decided to walk back this time instead of riding that creature from before. We wanted to spend as much time together as possible before I had to leave. It gave me a chance to really get to know Shadow. Of course, I knew him before, but now I knew even more. For instance, I now knew his favorite color was orange, his favorite book was "1984" by George Orwell, and a lot of other little 20 questions facts about himself.
It was really interesting to get to know him like this. It was fun even. He asked a lot about me too, though he already knew more about me than I knew about him. Apparently, all those times he was around and I thought he wasn't paying attention, he actually was listening to what I had to say. It was a heart-warming thought, really.
The walk back to my arrival spot went by fast. Just a little too fast. I was already starting to miss him. I shouldn't though. I'd be seeing him again as soon as I got back. However, I was afraid it wouldn't be like this between us ever again. Shadow kneeled down as he inspected the ground, probably trying to trace chaos energy to figure out exactly where I should teleport.
He drew a small "X" on the ground and stepped aside so that I could stand there. I hesitantly stood on the mark and I stared down at the emerald in my hands, feeling disheartened that this journey was coming to an end.
"Well then… I guess, this is goodbye."
I lifted my head to look in his eyes and I smiled sadly at him. My grip on the emerald tightened as I tried to keep myself from throwing myself at him.
"Yeah. Thank you, Shadow. For everything."
He put his hands into the pockets of his cloak and took a deep inhale through his nose, letting it out in a soft exhale.
"For you, Amy? Anything," he chuckled to himself and kicked a little snow with his boot, "You did good in there by the way."
"Oh. That wasn't anything… I just said what needed to be said."
He nodded in agreement to my words before he stepped towards me. He put his hands on my cheeks and leaned down, kissing my forehead.
"Don't forget what you promised me, alright?"
My eyes fluttered shut and I purred in content. I wanted to soak up these last few moments with this Shadow. My Shadow. I nodded my head to what he said.
"I promise I won't forget."
"Good. Also, make sure you go to a time when you weren't there. Otherwise you could create a cluster fuck of a time mess."
I couldn't help but laugh at what he said.
"Alright, bossy hog."
He stepped away from me and signaled with his head that it was time for me to go back. Fortunately, past Shadow's training was still lodged in my brain. I focused really hard on where I wanted to go. I decided to go back to the day after I disappeared. I didn't remember the time I teleported so that was the safest option.
I closed my eyes, and took a deep breath. Before I used Chaos Control, though, I looked to Shadow one last time and spoke with confidence.
"By the way, I made my decision."
He rose a brow to me curiously, knowing I was referring to our future together.
"And?" he questioned.
"I'll tell you when I get back to my time."
"You're mean."
I giggled and waved goodbye before I uttered the words, "Chaos Control".

When I arrived back in my time, it was in the middle of the night. The moon was high, the stars were out, and I was surrounded by Emerald Park. I was home. Finally. I took a moment to take it all in. I kneeled down on the grass and ran my fingers through it. I missed the grass, so much. I missed everything about my time. I was so happy everything was back to normal.
I heard someone clear their throat and my head shot up to see who it was. It was Shadow! He was standing there rather awkwardly, not really sure what to say to me. It looked like time hasn't passed at all, as if I was back at my lesson the day I left. I thought I came back to the day after. I guess I still have yet to perfect my time travel abilities after all.
"How long was I gone?"
He looked at his G.U.N wrist watch to check.
"About 4 minutes."
Good. At least I came back to a time I was already gone. At least my friends didn't have to worry about me.
"Where exactly did you go anyway?" he rose a brow, curious to find out.
I looked down at the chaos emerald and smiled to myself. I then handed it back to him. He looked confused as to why I was giving it back.
"Don't you want to finish the lesson?"
I shook my head and took his hand. He stiffened a little and looked at me like I was crazy.
"You wanna go get some coffee or something?"
He furrowed his brows, but hadn't pulled his hand away from me yet.
"What happened while you were gone…"
I giggled and started to pull him along with me.
"Do I have a story to tell you."

200 YEARS LATER
The End

It was a bright sunny day out. Flocks of birds flew through the sky, creating a symphony of sweet chirps. Shadow was walking a trail along the mountain tops just outside of the city. Back when she was still alive, they had built a cabin up here together. She loved nature, and he hated crowds. It was the perfect place for the both of them back then, and still is.
He remembered the day she time jumped, and told him about her adventure. Almost as if it had happened yesterday. She told him about how an asteroid sent by Eggman sent the world into an Ice Age, and how the two of them worked together to her back to her own timeline.
He also remembered how shocked he was when she told him what happened between them while she was there. That the two of them fell for each other, or rather, she finally returned his feelings for her. At this point, it seemed like it was all just a dream. Them being together was so long ago.
If he remembered correctly, today was the day that she landed in the future. This day could have been covered in ice and mobians would be living underground barely surviving.
Because of her though, and her stubbornness to get back to her friends, that day would never come to pass. She saved the world, and the world would never even know it. She never told the rest of her friends about it, and of course, Sonic and Shadow got the credit for saving the world; but that sort of thing was never really important to her.
All she cared about was that her friends were safe. And that was something Shadow had always admired about her.
"Hey! Papa! Wait up!"
Shadow stopped in his tracks and looked behind him, to see a pink male hedgehog with pale yellow eyes racing for him. It was his great grandson, Axel. Him and Amy had a child together. He had to admit, it was painful to have to watch her, and his child pass on without him; but he still had his grandkids and great grandkids to fill his life with the same joy they did.
"Hey squirt. What are you doing all the way up here?"
"I-" he took a moment to catch his breath. After all, his little legs ran an awful long way to catch him, "I wanted to walk with you!"
Shadow smiled and he picked up Axel and set him up on his shoulders.
"Alright then. Let's go."
Axel hugged the top of Shadow's head and purred as he relaxed. It was so odd to Shadow to be having a great grandkid. Back before him and Amy get together, he didn't even like kids. And now here he was, with a kid, who happened to be one of his best friends in the world.
"Hey Papa."
"Mhm."
"Can you tell me the story about how my great grandma saved the world again?"
Shadow sighed to himself. He'd told him that story so many times now. He could never tell it as well as Amy could, but he tried his best when he had to.
"Well you see, it started when your great grandmother wanted to learn how to use a Chaos Emerald."
