WARNING: This article contains major spoilers for “O, Mouse!”, the Batwoman Season 1 finale.
In the Batwoman Season 1 finale, Alice pulled her cruelest move yet: she killed her “brother” and confidant Mouse.
Over the course of the season, Mouse grew more and more frustrated with Alice’s lust for revenge. Finally, in “O, Mouse!”, he reached his breaking point and gave her an ultimatum. He planned to leave Gotham with or without her, forcing her to choose between him and her vengeance. Unfortunately for him, she chose the latter.
Just before she killed him, Alice held a ceremony where she burned their copy of Alice in Wonderland. “I destroy the thing that anchors us to our pain so that we can move on,” she said as the pages went up in flames. “This book is our chain. It locks us to the Caterpillar, the Queen, that basement cell. It binds us to every terrible, twisted thing we were forced to endure. Burning it breaks our attachment and frees us to move on, which we always intended to do. Move on.”
“What happened to us should never happen to anyone, but there’s no one in the world I would have rather gone through it with,” Mouse muttered.
“Nor I without you,” Alice choked through her tears. “And I mean this with all of my heart. I still want to join you in the beautiful garden and smell the seasons in bright flower beds and make a wish in cool fountains. I want to meet a man with many hats and smile back at the Cheshire Cat and run with you forever through our Wonderland.”
As the spoke, blood began to trickle out of Mouse’s nose, and she burst into sobs. When he touched his lip and saw his bloody fingers, his hand began to shake. “Alice?” he asked, bewildered. Then, upon seeing her expressioned, he realized the terrible truth: she had poisoned him. “No!” he cried. “What did you do?”
“You made me choose,” she spat. He asked why she poisoned him, only for her to say, “Because I couldn’t let you leave me! Not you too!”
“This wasn’t even real?” he realized. He keeled over onto his side, landing with his head in her lap.
“If only pain could turn to ash with the strike of a match,” she whispered, stroking his hair. “But my pain is a part of me, the way my family is a part of me. You could never understand why I need to enact my revenge, because you’ve never experienced true betrayal — at least, not until now. Goodbye, my sweet Mouse, my brother, my everything. I’ll see you again in Wonderland.”
Since the start of the season, Mouse has stood by Alice’s side and acted as her accomplice as she terrorized Gotham with her Wonderland Gang. Though they are not related by blood, they were raised together after Dr. August Cartwright kidnapped her. Cartwright taught her how to create convincing masks out of dead flesh, so that Mouse’s appearance could be fixed. Eventually, she used this skill and Mouse’s ability to mimic others to jumpstart their life of crime.
Where Mouse just hoped to escape his father, Alice wanted more than that. She wanted revenge on her father Jacob and twin sister Kate, as she believed they gave up too easily on finding her following the car crash that took their mother’s life. As Kate thwarted her at every turn, Alice became more and more obsessed — so much so that she started to push Mouse away. Unfortunately for him, she has trouble letting things go, which ended up deadly for him. And if she is willing to kill the sibling she loves, she must have some seriously torturous plans for Kate.
Returning to The CW in Jan. 2021, Batwoman stars Ruby Rose, Rachel Skarsten, Meagan Tandy, Camrus Johnson, Dougray Scott and Nicole Kang. The series airs Sundays at 8 p.m. ET/PT.
