Justice League had more than its fair share of Superman/Batman Ho Yay, the pinnacle of which occurred in the episode "Hereafter". Superman is vaporized in the first act, and Batman's response is to carry around a scrap of his cape, finger it absently while reviewing a tape of Supes' death ad infinitum, and maintain to anyone who'll listen that he's not quite dead. Of course, this being Batman, he's right, but League members still manage to call him out on his stoic bullshit. And then there's this speech:
Batman: I've got some things to say. I should have said them when you were here, but... despite our differences, I have nothing but respect for you. I hope you knew - know that. You showed me that justice doesn't always have to come from the darkness. I'll miss - "
