The Flash, Season 1

Iris:
To understand what I'm about to tell you, you need to do something first, you need to believe in the impossible. Can you do that? Good. Because all of us, we've forgotten what miracles look like. Maybe because they haven't made much of an appearance lately. Our lives have become ordinary. But there is someone out there who is truly extraordinary. I don't know where you came from. I don't know your name. But I have seen you do the impossible to protect the city I love. So for those of us who believe in you and what you're doing, I just want to say thank you.
