She should be. It's hard for A2 to struggle to her feet, and she knows the blade won't do anything, so once she's up and running at Kara, she's swinging with her bare fist. Which will do even less, but the angry plea that comes from deep in her mechanical throat, drawing power from her own artificial heart is clear. "Get away from that!"

She only exists in the memories of main(), after all. Doesn't everything want to keep surviving?
