Wouldn't it be nice if Sonic had found the other inhibitor ring?
I'm sure by the time Paramount releases the next Sonic project the crew has forgotten about this scene...
...or that Shadow only picking up one inhibitor ring was just the cooler visual than him already wearing one and picking up the other.
But it would be super sweet if Shadow was missing a ring the next time he shows up and it turns out that Sonic had found it and held on to it, meaning he was not ready to let Shadow go.
Sonic and Shadow have the best chemistry of all the videogame characters out there.....so something like this would be very fitting in their story.
