Once Barry does finally give in and give Jay Garrick some leeway, the Scarlet Speedster is soon being told about a new trick that hell need to master in order to take down Sand Demon. That trick, of course, is to essentially generate enough energy to punch/throw lightning at his foe. Even with Harrison Wells out of the equation, its cool to see Barry still picking up new skills as he continues to grow as a hero. And its even cooler that one of these skills is reminiscent of Guiles iconic Sonic Boom from the Street Fighter video game series.
