      3.86 terajoules is actually a lot less energy then the sun emits in an hour. Each hour the sun produces 1.4 x 10^19 terajoules of energy (expressed as a whole number that would be 14 followed by nineteen zeros).
    • Quotes

      Joe West: I don't understand. How could Savitar be you?

      Barry Allen: He's not me. Not really.

      Cisco Ramon: He's all the worst parts of you. It's like in "Star Trek" when the transporter splits Kirk into Good Kirk and Bad Kirk.

      [to H.R]

      Cisco Ramon: Please tell me you at least have "Star Trek" on your Earth?

      H.R. Wells: "Voyager".

      Cisco Ramon: I hate spinoffs.

    This is nice!
    Well, let me be clear about the rating 9 that I have given to it may seem higher and it is but I have to give this because overall the episode is underrated enough. So clearly, you have to look at this from a different perspective and understand what this episode was about for me this episode explained a lot about Barry and why is he like what he is like. So let me tell you what to do grab some popcorn and a cola then enjoy the episode and most importantly take it lightly and eventually, you will follow.
