sonic,tails,knuckles,and shadow were bored so they went on a walk,when they were walking Sonic sees a hedgechog-like person thing like him on a mountain by of where they’re walking,Sonic stops and speaks

sonic:”Okay, either that’s my long-lost twin... or Eggman’s been busy again…” His voice is casual, but there’s a flicker of nervous energy.

Tails:I’m not picking up any EggTech signatures... but there’s definitely something... weird about its energy." He edges closer, curiosity written all over his face.

Knuckles: "Looks like a challenge. We should go up there. Now." Already halfway up the trail, because Knuckles doesn’t wait for exposition

shadow: "Hmph. That stance... it’s deliberate. Whoever—or whatever—they are, they want us to see them." Then he vanishes in a flash of Chaos Control, reappearing ominously halfway up the mountain.
