That would be nice but Captain Cold is dead unless somehow bringing him back for tonight's episode causes something related to time travel being the only explanation where it seems a S1 Legends Leonard, so the changing Leonard and the one that ends up sacrificing himself
and becoming the Hero he didn't want to be but again they would have to get Wentworth to sign for a contract for it
and believe its been very quiet without having any news on what he's doing
Plus already know it ain't a speedster finally that is the big baddie
I was thinking KF
