In the Lucifer comic series, Jill Presto used to be a vessel for Basanos, a living Tarot deck. Their relationship didn't end well, Basanos forcefully impregnated her against her will. She managed to "abort" one of the fetuses, but she founds that there is one more child inside her, one that wants to kill her. Oh, and the end of world is coming, since Yahweh quit the job and creation is unravelling.
Following the guide of a dying psychic, she goes to Las Vegas and bets all her considerable money on a LOSING number. Then she finds this interesting gentleman waiting outside for her commenting on her bet:
Since most gods usually like to introduce themselves by name, I find it very weird that we never know this "gambler" (as it was called by someone else) name. And there in "American Gods" we have very similar god living in LV, who never introduces himself and also seems to take a keen interest in gambling.
This might be a long shot, since the "Sandman-Lucifer" universe is not the same as the "American Gods" one, but I'm just curios, have Gaiman or Carey somehow copied from one another?
