with versions I mean there's basically Silver who went through what happened in 06 and then there's the Silver who never experienced that (because the events of Sonic 06 were erased pretty much) it's a little complicated I guess haha ;;
I think that's what you were referring to as well? :'o
as far as I know that's actually the case for the Silver that appeared in the DS version of Sonic Colors for a brief moment ;; he was so happy haha... sighs
