Barry Allen rambling from "The Flash Reborn" came to light through the repeating of the words, "I'm innocent, your honor; I didn't kill anyone".
Anton Slater opened his first speech with the words "For you to understand what it is I'm about to tell you today, you need to do something. I need you to believe in the impossible." It is very similar to the first line that was ever said on the show, in the first episode "Pilot".
