Ruby Rose's Batwoman will air at Sundays at 8 p.m. this fall, followed by Supergirl at 9 p.m. The CW also announced Arrow is moving to Tuesdays for its final season, reuniting with The Flash. Nancy Drew will air after Riverdale on Wednesdays, while All American will move to Mondays as a lead-in to Black Lightning. Charmed and Dynasty will air together on Friday. Meanwhile, Riverdale spinoff Katy Keene will be held for midseason. "Launching Sunday was a big success for us last year and we see even more upside with this powerful combo," The CW president Mark Pedowitz says of the Batwoman-Supergirl pairing.
