In an intriguing WTF moment, we get to see Barry Allen go rogue as he takes on the alias of Sam and becomes part of Lewis Snarts operation. This little twist on things lent itself to allowing for some great back-and-forths between Barry and Captain Cold, not to mention show Barry doing his best to keep the body count down as a diamond heist gets underway. Oh, and it was also pretty damn cool to see The Flashs powers come into play when trying to decipher a security doors key code panel.
