Supergirl, Season 5

Alex:
Well, this should help take away the pain temporarily.

Kara:
I don't understand. You think that whoever did this to you was also the person that released Midnight?

J'onn:
Yes. He said he was my brother. At first, I didn't believe him, but now I know it must be true.

James:
How do you know?

J'onn:
This is specifically a Martian form of agony. In the early days of Mars, there were two brothers, Phobos and Deimos. Their rivaly and bloodshed was the reason for the split of the Green and White Martians. To prevent this ever happening again, a curse was placed on the Green Martians. We call it Fa'ra'too'rik. It is the punishment for brother attacking brother.
