Tails EXE is about 13-14 years old in this. That's why he looks older and his voice is deeper. The real reason sonic died is bc shadow sadly killed him. Honestly guys, this is probably the saddest story I have ever seen TwT ~~~~~~~~~~~~~LYRICS~~~~~~~~~~~~ Tails: was I really worthy of this adventure? Did people even like me? Or did they just like sonic? poor poor fox lost to time. poor poor sad soul to death. sad sad tails was it just a dream? I feel like lost alone without sonic. I feel like lost alone without no one. Does anyone even care about about me? I'm just a hated soul with nothing special. Sonic is special but i'm not. Am I even good? Living alone in the deep dark mind no one here to rescue me.No sonic to save me. Alone in the darkness. Sonic: I'm here bud! Don't panic everything is gonna be okay. Keep the courage you are not alone. Now everything is fine. Keep believing in yourself keep trusting your soul. Keep trusting in your friends and family! Tails: I need to trust in myself. Sonic is still here with me. I just can't see him. The darkness hides him but I know his soul is still here. My dear soul, thanks for saving me. Thanks for believing in me. Thanks for being my friend. Thanks for being here with me. thanks for making me understand that you can get hated, but you still have your family and your friends. We are both special. Thank you sonic for trusting in me in your adventure, and for being my friend. I didn't have any. More reasons to hide from all the hate I got now that I have you. I can always trust you will never let me down. Thanks for meeting me. Our adventure still continues. Sonic: Looking at the ground thinking how everything can go wrong will only slow you down bud. And you know I hate slow! Just keep looking what you can do to fix the problems you see! That's what I did! Things may look gray now, sure. But there is a whole world of color just waiting for us! You just gotta know where to look! WHERE I GOT THE LYRICS FROM: https://www.youtube.com/watch?v=kD6MiQV7nHc
All cred goes to @AmirTheHedgehog8 In the last two tails sprites is where he turns back to regular tails. That's why his eyes and color changes. So, what happened is Tails turned into Tails EXE when sonic passed away. And, when Sonic talked to tails it makes tails EXE go away bc tails isn't sad when sonic talk to him.
