This year’s Arrowverse crossover, “Elseworlds,” wasn’t just a precursor to next year’s “Crisis on Infinite Earths” (although that’s definitely a big deal) – it also finally introduced Batwoman and Gotham into the CW’s superhero universe.
And that probably won’t be the last we’ll see of Ruby Rose’s Batwoman, since The CW is currently developing a potential spinoff series for the Dark Knight’s cousin that’s under consideration for next season.
