Young Justice, Season 1

[Miss Martian's counseling session Black Canary]

M'gann M'orzz:
It was all my fault. Hello M'Gann. Who else could take a simple exercise and turn it into a nightmare that terrorizes everyone she cares about?

Black Canary:
You've turned white.

M'gann M'orzz:
[gasps] NO!... Oh, you meant Caucasian. Yeah, I'm fine being Megan, but I can't be trusted to use my other powers.

Black Canary:
M'gann, you're a Martian. Not using your natural abilities is like me refusing to speak. Which, by the way, I tried for a while after my very first Canary Cry. Nearly deafened my entire First Grade class. So I get how you feel. But not being yourself is never the answer. And it won't make your feelings of guilt go away. Learn from what happened. You uncle would be happy to train you. Practice until you have more control, and regain your confidence.
