A few years after the events of the latest Sonic game, Shadow the Hedgehog travels the world working for different G.U.N branches. When he returns he’s in his 20′s and catches up with his friends. Omega and Rouge are at different G.U.N branches, so he doesn’t see them as often but they keep in touch. Shadow now hangs out more with Sonic, Tails, and The Chaotix when he has the time. The only one he hasn’t seen yet is Knuckles, who is on his own hiatus. When weird chaos-related incidents start happening in Station Square, he hears news of Knuckles’ return, and he goes to meet him.
When he sees Knuckles in the woods talking to Sonic, Shadow notices how tall and strong he’s become. Before he realizes it, he’s been staring at Knuckles for a long time. It’s then that Knuckles spots him, and walks towards him to greet him.
As Knuckles approaches him with a big smile on his face, it’s then that Shadow is hit with...another feeling.
