This episode reminds me of nora many times. It's actually not a seson beginning episode it's some part of the end of season 5 too. As usual there is always a new meta show up in every season so as it is. A classic flash episode that shows the path of crisis in many ways if you did notice carefully. Background music is really terrorised you. Although we see here some over confident barry and some struggles of killer frost being catlin. I love that how they coming to crisis slowly and also you suck into the void with some great music background. I love this. ⚡
