Lena glares at the back of Kara's petulant frame as she storms off.
She knows that she has been ignoring Kara all night, on date night, but she can't help but feel that her girlfriend was overreacting. She feels misunderstood. Even when they were only best friends, Kara had known she was a workaholic, and she was the most understanding person in her life, always bringing her food and coaxing her gently, patiently, to go home. Yes, Lena always had work, but Kara always had people to save - and Lena never complained about that. She took all the neglect in her stride, never made a fuss even when Kara disappeared onto another Earth for days on end - so why couldn't Kara do the same for her? Lena's face hardens and for the first time in a long time, she hears the old Lena's voice in her head, saying, I told you - you're better off alone. No one understands what your work means to you, so you shouldn't expect them to. Kara is just like the others - she'll leave, in the end, because she can't stand coming in second to your work.
She waits for a minute to see if Kara would come out, head hanging, puppy-dog eyes cranked up to fatal levels, if Kara would bury her head in Lena's chest and say she doesn't want to fight. But Kara stays in her bedroom.
And so Lena packs up her things and leaves, not bothering to stop the door from slamming.
She hates that she is already in tears by the time she gets to the elevator. Old Lena's voice keeps getting louder in her head.
