I'm just imagining that everyone we see pictured is hearing Scourge's laugh across Mobius, with Sonic and Sally thinking "Ah great, like we didn't have enough noisy neighbors already", Blaze and Silver thinking "Sheesh, someone loves being a giant ham.", Rouge is thinking "For fuck sake, either kill me or shut up!" and Tails is thinking "Hmmm, where did I place my ear plugs?"
