When one of Gotham’s former heroes returns to his old stomping grounds to settle a score, both Batwoman and Commander Kane find themselves on the defensive. Meanwhile, Alice has uncovered what could finally take down Batwoman, but she is losing hold on her partners Mouse and Hush (guest star GABRIEL MANN), sending her spiraling into her most wicked self. Luke immediately focuses on finding a way to protect Batwoman from Alice, and Mary finally has a chance to be the sister Kate has needed all along. New information surfaces, forcing Julia to warn Sophie about the person pulling the strings. And in a final standoff, Commander Kane refuses to retreat from his war on Batwoman, which finds Kate more than heartbroken by her father’s choices in the first season finale.
