In a new interview from Comic-Con Grant Gustin (The Flash) talks about Erza Miller, Season 2, and the white logo. There are some intresting comment in this interview, including Grant confirming that he will be wearing the white logo in Season 2 and that it IS NOT the suit from the future Flash seen in Season 1. He also sheds some light on that prision scene that veiwers caught a glimpse of in the speed force. Although he does not confirm this, based on his comments, I have no doubt that image was hinting at "The Trial Of Barry Allen" storyline. In this story line The Flash kills The Reverse-Flash and faces trial for his murder.
The Flash returns October 6th
