Felicity: Remember when you told me you had a little experience, liking someone who didn't like you the same way? That was Iris, right?
Barry: How did you know?
Felicity: It's the little things. The way you linger on her when she isn't looking, the smile you fake to play the part. The quiet dreams you keep to yourself.
Barry: Like you and Oliver. Takes one to know one. I'm afraid it will change everything.
Felicity: It will, but maybe that's not such a bad thing? What is wrong with us? We are perfectly perfect for each other.
Barry: Yet we're sitting here pining for people we can't have. I guess what they say is true. Opposites do attract.
