It looks like we're getting a glimpse of how Sonic came to be at this place of sin! I don't blame him. If I were him I'd probably follow Shadow too (especially if he was dressed like that).
I'm also going to be using this space to reply to comments for each of the comic strips. I'll answer questions left for me on prior strips but please understand that if I feel a question might cause some spoilers I might give a vague answer to avoid that happening!
So, let's get to the ones on the first strip shall we?
