Synopses for final 2 hours of Crisis on Infinite Earths tease Oliver’s return, the big finale

We still have to wait a few weeks to see the epic conclusion of The CW’s Crisis on Infinite Earths crossover, but the network’s synopses for the final two hours of the event drop a few tantalizing hints about where the story is heading next.

Parts 4-5 of Crisis are set to air back to back on January 14, technically included in episodes of Arrow and Legends of Tomorrow (though the Crisis event has largely transcended the host shows themselves). So what do we learn from the tease for the big finale? Fans still reeling from the death of Oliver Queen (Stephen Amell) can take a bit of solace in knowing that, yes, he’s apparently still sticking around in some form. After Oliver met up with the Spectre in Purgatory following his death in Hour 1, it sounds like he’s since taken up that supernatural mantle. It stands to reason that could help out with the last episode's cliffhanger that found the few remaining heroes with no Earths left to defend.

As for the final hour, the network kept the details pretty light. All we get is a tease that “worlds lived” and “worlds died.” So does that mean some worlds we know will remain destroyed in the wake of Crisis? That’s anyone’s guess, though it stands to reason some realities that don’t host TV shows could remain destroyed once this is all said and done. But what about Black Lightning’s world? Or Supergirl’s world? Will those be restored, or somehow be merged into Earth-1 once this thing is all said and done?
