Did you realize what was going on in this episode?
The actor who played the Trickster is none other then Mark Hamill this is the actor who played Luke Skywalker in Star Wars Episode 4,5 and 6 He is also going to be in the new Star Wars movie. He also played the first Trickster in 1990 CBS series The Flash. The current Flash series has been produced so well that they knew this and got Mark Hamill to play the role once again. He did a great job.
One other awesome thing they did in the episode is that the trickers trains a young boy to help free him from prison. Once he is free from prison the Trickster talks to the young man and asks him if he knows why he chose him. The young man doesn't know so the Trickster looks at him and says "I AM YOUR FATHER!" are you freaking kidding me I almost lost it when they let him say that exact line! A few years prior to this Mark Hamill had this said to him by the sith lord Darth Vader!
The Flash keeps getting better and better I am very happy with this series so far. If your not watching it deffinately start!
