[[WMG: The movie is a (direct?) sequel to ''[[WesternAnimation/SupermanDoomsday Superman: Doomsday]]''.]]
For two things [[@/TitoMosquito I]] can think of:\\
1) Clark and Lois are married and she knows Clark is Superman.

2) There are robots operating at the Fortress of Solitude. He had one in ''Superman: Doomsday'', so he might have made more and with different designs by the time of ''Superman vs. the Elite''. He might have gave the original robot a new body as well, and he was the one who flew Lois to England and back to Metropolis.

* May I add one thing, the theme tune is the same.

[[WMG: The whole time, TheJoker was in Arkham, watching the news reports of it and laughing his ass off]]
Why? The public was supporting the Elite's lethal methods. The way Joker saw it, this just proved that he had been right about everyone else being no better than he was.
* Batman is also watching the news, and [[Film/TheDarkKnight is probably reminded of what the Joker said]].
