Leviathan was name dropped in last season's final episode of Supergirl, so they pull from very recent stories for this stuff all the time. I hadn't thought about Jor El, but it actually makes quite a bit of sense. Having Sam Lane apparently be a main cast member as well makes that look likely.

I don't really like the way this Lana stuff could be set up. Down on her luck Lana pining for Clark is never a good use of her character. Chuck Austen torpedoed his career with that nonsense (among other things). So hopefully CW doesn't go there.

Clark getting fired and Lois still working at the Planet is interesting. But I definitely wanted to see them together as reporters.

The twins thing is just an odd choice though. Not sure where that's going.
