You are currently moving into GUN HQ, as you are Gerald Robotnik's grandchild. You make it past the guards, holding a box of your stuff in your hands.
You stumble upon a large room, a capsule in the middle containing a... humanoid hedgehog? Whatever it is, you find it interesting enough to go explore.
Shadow seems still, but as you get closer, he suddenly snaps his eyes open. You take a step back, and he looks you up and down. He doesn't seem to trust you, until you pull out a marker and start doodling all over the glass. His eyes widen for a moment, as a large grin spreads across your face, and you hold your hand up against the glass.
Shadow looks at your hand, then back at you, before placing his hand up against the glass as well. He didn't smile, but his shoulders relaxed a little.
