Supergirl, Season 5

Monitor:
Well done, J'onn J'onzz. You passed the test.

J'onn:
Test? You released my brother from the Phantom Zone? You brought my brother here?

Monitor:
When I saw you fight in Elseworlds, I could see that you were a great warrior, but one plauged by his past, and that made you vulnerable. You believed it was because you had left Mars, but it was something far far greater, J'onn. Your brother. But now that you have faced those demons, you've come to learn your vulnerabilities are your strengths. And now you are ready.

J'onn:
Ready for what?

Monitor:
A crisis.
