The 3 heros (and Shadow) were walking around the town. They were showing Shadow around and what the human life has included. Shadow didn't seem very interested in it though.
You were from Sonic's real world, before he came to earth. You somehow got to earth to search for the missing creatures. And you saw them with Shadow, somehow you knew Shadow lmao and it surprised you.
You stalked them through the day, with a cloak covering your head. And somehow these boys are thicker than ice so they can't see you in plain sight. But later Sonic went out by himself due to being bored of helping Tails with the chores Maddie gave them. Knuckles and Shadow basically said "screw off" to the chores and Maddie grounded them. ( ͡° ͜ʖ ͡°)
But as Sonic was surrounded by multiple metal robots. As Sonic tried to fight, he realized he wasn't gonna defeat these robots on his own.
Sonic: "Hey buddies...lets talk about thi-...wait, you're robots-"
You mentally facepalmed when Sonic was being a bit ignorant. So you defeated the robots instead, and destroyed them infront of Sonic. Who was trying to catch a glimps at you.
Sonic: "Wait! Who are-...what?! How did-?!"
He couldn't keep sight of you until you stopped and removed your hood to look at him
Sonic: "Hey-...oh...ahh h-hey"
He said while his quills glowed and his cheeks went red
