The Flash, Season 2

Speed Force Iris:
We thought you'd find this place and our appearance less upsetting. Yet you seem upset.

Barry:
My friends, my city... my whole world is in danger. Zoom is on a rampage with the power that he stole from me, and you are keeping me here.

Speed Force Iris:
You were given a rare and precious gift. And you rejected it.

Barry:
No, I did not reject it. I gave up my powers to save someone's life. To be a hero. I nearly killed myself trying to get them back when you brought me here, wherever here is.

Speed Force Iris:
That's not what we meant.

Barry:
Look, if you would rather have given these powers to somebody else, why did you give them to me?

Speed Force Iris:
Because you're the Flash, Barry.
