'Crisis On Infinite Earths' Part 5 preview: Nothing will ever be the same for the heroes of Arrowverse

After three rattling episodes, 'The Crisis On Infinite Earths' will conclude on January 14, with what promises to be an epic showdown with the Anti-Monitor and his grisly forces. As the trailer shows, the Arrowverse heroes have managed to weather a lot of storms, yet their journey has far from ended, as they still have to bring back their loved ones. The final team includes the Green Arrow (Amell), Supergirl (Melissa Benoist), The Flash (Grant Gustin), White Canary (Caity Lotz), Batwoman (Ruby Rose), and J’onn J’onzz (David Harewood) and they're willing to fight to the death to restore the multiverse.
It will be aired on January 14, 2020, at 8 pm ET, followed immediately by Part 5, DC's 'Legends Of Tomorrow' hour of the crossover, which will deal with the post-Crisis Arrowverse. The synopsis of part 5 reads, "THE EARTH-SHATTERING 'CRISIS ON INFINITE EARTHS' CROSSOVER CONCLUDES. Worlds lived, worlds died. Nothing will ever be the same." Gregory Smith directed the episode written by Keto Shimizu and Ubah Mohamed."
Not exactly the most helpful, but nevertheless provides viewers a small insight into the horrors the Crisis left behind. While the other DC shows will continue Post-Crisis, 'Arrow' will conclude with the backdoor pilot of 'Green Arrow And The Canaries'. Arrow most likely will get the death fans wish for him--- to die in Felicity Smoak's arms.
As we saw in Part 3, everything was as hopeless as it could get. the Anti-Monitor had annihilated the entire multiverse. Every Earth was wiped out, barring the Vanishing Point, where the superheroes are trapped. The Spectre, who has taken the form of Oliver Queen, is on their side, but will it be enough to bring down the super-powerful force?
The latest photos from CW seem to show that one earth seems to have been restored. Could the heroes have reversed the plan of the Anti-Monitor? It remains to be seen. It's quite possible that the usual and favorite plot device of Time Travel was at play here too. In the photos that were released by the CW, we can see the group of heroes, comprising Supergirl, The Flash, Atom and Heatwave ready for battle.

And there's a photo of Supergirl with Atom too.

The heroes had one casualty in the first episode itself, as Oliver Queen (Stephen Amell) died a hero's death while trying to save the multiverse. However, that's clearly not the death that was intended for him, and he has returned as Spectre. And it seems to be him, who has united all the superheroes for battle.
Who lives, who dies, we'll find out in the epic crossover conclusion on January 14, CW.
