Lena had lived a thousand years and never has she felt such shame. Not even when she slay her own brother at Camelot. Ever since then she swore she would never perform such terrible acts again. And for the better part of several centuries, she had succeeded even managing to bypass wars across the globe. But never has she felt this terrible, and the reason she feels so terrible is that she knows what it is to be forced by others perception of her. She still remembers the smells of smoke and fire from when she had been tied to the stake as a village decried her a witch.
And yet here she was and honestly she hadn't even realised. Kara had seemed so normal Lena had never imagined something as trivial as a pair of glasses would be such a big deal to the blonde. She had taken them off the blonde against her protestations and then been forced to watch as Kara crumpled. She had replaced the glasses immediately, but by then the damage was done. The blonde was curled in the foetal position on her couch, her hands over her ears, her eyes clutched tightly shut. Tears leaked from her eyes as the rocked and Lena thinks about what could be causing it, surely she's seen Kara without her glasses before. It's then that she realises she hasn't, the realisation, the truth, it hits her like a freight train.
Holy shit, Kara's Supergirl.
But why would today be any different, it's then she remembers the distortion of her phone, the way her internet had been acting up.
A solar flare.
Shit.
For the first time in nearly a century, Lena uses her powers again. She watches as the office is plunged into darkness, thick material covering the walls as Kara seems to slowly stop and peek carefully from behind clenched eyelids. When she isn't met by an assailing blast, she opens her eyes fully to see Lena knelt before her.
As soon as she sees the blonde open her eyes Lena begins to apologise, she begs Kara's forgiveness. Slowly as she speaks, she finds herself telling Kara more than she has spoken to anyone before her. She watches as Kara seems to realise just how sorry Lena is. She watches as Lena reveals herself and Kara's eyes widen. She watches as Kara's face becomes one of awe as she looks at Lena and what her magics have done. She nearly cries with relief when Kara pulls her into a hug, she does when Kara refuses to let her go.
