I mean if they had confirmed it was anyone else after the way the mid season finale went I would've been completely turned off of the show simply for the storyline making zero sense
The article did say something about still having Eddie Thawne connected into the Reverse Flash lore but I have no idea what that would even mean as far as the show is concerned, I know that in the comics that is who the actual Reverse Flash/Professor Zoom was.
I can't wait til the show returns with the Rogues starting up aka Captain Cold & Heat Wave to start it off, I believe a week from tomorrow is when it returns and then Arrow the next day.
