Fan Casting Post-Credits Scene in World's Finest

Superman is seen at night sitting on top of the Daily Planet while watching the sky alongside Supergirl, where they both agree it's been quite the day. He then asks his cousin if she could still patrol Metropolis with him the next day, with Kara saying that even if she did, she had arranged to go out with Barbara. The scene ends with Superman laughing, as he says that he and Batman will have an impossible challenge to separate the two girls from now on.
