Berlanti's Superhero Crossover Starts Tonight

Betty, reminder to record tonight from 7-9 PM CT, your time, 8-10 PM ET. It will say Supergirl and Arrow, record for two hours! Tomorrow night, same thing. Tomorrow night it will say The Flash and Legends. Record both shows for the final part of the crossover!

So two hours tonight, two hours tomorrow night. Crossover is completed after tomorrow night!
