Supergirl, Season 4

J'onn:
I saw Manchester at the bar while I was grabbing dinner. He wanted me to tell you how sorry he was.

Kara:
J'onn, you told me Manchester is on the path of peace, like you.

J'onn:
We share a similar struggle, yeah. So I understand how much he wants to feel like he's doing something, and how hard it is for him to resist his more violent urges.

Kara:
You don't think he's capable of killing five Children of Liberty, do you?

J'onn:
I mean he is angry, but under that anger is just a lot of pain. Fiona's death just rocked him. Manchester has a good heart, and I'm not ready to give up on him just yet. I mean, he's been on our side every step of the fight, he's resourceful and stubborn, and if he wants something he'll go after it. He could be useful.
