Misaki Han vs. the World
Yes. Ellen Wong, who plays Four's nemesis, Misaki Han, played Knives Chau in Scott Pilgrim vs. the World (2010).
Also, this week's episode title, "Take the Shot," is taken from a line of dialogue (said by the Android Simulation). Do you know what other two lines of dialogue were title contenders?
Oh, and guess how long it took to shoot the sword fight between the aforementioned nemeses? They weren't done by lunch, we can tell you that.
