Batwoman will return from midseason hiatus later this week, and the second half of its third season definitely has a lot of narrative ground to cover. Among that is the show's take on Poison Ivy — both the "Poison Mary" that Mary Hamilton (Nicole Kang) has become, and the lingering question of Pamela Isley (Bridget Regan). While Regan has yet to make an appearance on Batwoman, her debut on the show has been heavily-hyped, and a new series of photos revealed by TVLine provide an unexpected look at her debut. In particular, one photo reveals Regan in her Poison Ivy costume, which bares a strong resemblance to the one Ivy wore in the "Arkhamverse" of Batman video games.
