Over five minutes of what is hands down one of my most anticipated shows! This extended look gives us a peek into Barry's younger days as he watched a "yellow flash" kill his mother. This of course confirms that the primary villain will be The Flash's arch enemy Eobard Thawn/Professor Zoom, a man from the 25th Century who uses the speed force to travel through time.
Also featured is a member of the Rogues (criminals with meta-human abilities) Weather Wizard, played by Chad Rook.
I am even more psyched, and if the minute teaser after Arrow last night wasn't enough... this more so solidifies that I'm looking forward to Fall.
