Between the show being a mid-season slot and all the COVID issues, it’s been a year since we saw the Legends of Tomorrow. The last thing we saw was the defeat of the Fates, a big celebration after, and then Sara unexpectedly kidnapped by aliens without the others seeing.
The Crisis on Infinite Earths continues on Batwoman. The first part had several cameos and a lot of surprises, as the extent of the high stakes was driven home by so many deaths. The special after-show, ala Talking Dead for Walking Dead, confirmed that all those worlds we saw in quick glimpses were destroyed, so the body count is already immensely high.
