Prompt: Leviathan ends up controlling Andrea or whatever when she hesitates to complete her mission and Lena keeps her word.
Andrea watches through her own eyes as her arm lifts and thrusts towards Supergirl. There’s a crunch of splitting flesh, and the coppery tang of blood, and a thud that reverberates Andrea’s arm and rattles Andrea loose from the invisible cage. She regains herself and her limbs just as she registers Lena’s face in front of her own.
“Lena! No, no, no!”
“I told you--” Lena coughs. Blood speckles Andrea’s cheek, splattering flatly against her mask.
“Why did you do that?” Andrea cries. “Why?”
“--have to go through me.”
Andrea’s next breath comes as a sob. It explodes from her, and seems to knock Lena off her feet. Her legs give out, and Andrea bolts forward to catch her. Cradling Lena in her arms, she slowly descends to her knees.
Please, she prays. Please let this be a dream.
But when she clenches her eyes shut Lena is still bleeding when they reopen, and she is still holding her best friend as she struggles to breathe.
“You jump, I jump,” Lena rasps. Her eyes can barely open now, her lips turning blue. “Remember?”
Andrea nods. “I do. Of course I do.” She wipes at her eyes, and screams with rage at the mask she finds there. She tears it off and throws it away, flinging it as hard as she can towards some other corner of the world. Somewhere it couldn’t taint the words between them.
“I loved you more than anything in my entire world, Lena,” Andrea whispers. “I need you to know that. Please.”
“I loved-- you too.” She coughs again, and more blood bubbles to her lips, clicking insidiously in her throat as she swallows. “Broke-- my heart.”
“I know-- I know, I am so sorry, Lena. It was the biggest mistake of my life, and I knew it the moment I agreed to take it. And then afterwards I let myself believe I was protecting you, but... I even failed to do that!”
A wet scoff chokes out of Lena. “Could do-- with less protection.”
In that moment, Supergirl surged to wakefulness. She lunged upright, then stared dizzily around the room until her eyes focused on the tableau before her.
“Lena!”
She surged towards them, only for Andrea to curl Lena tightly against her chest, containing the poisonous glow of the kryptonite still lodged in her chest.
“Stop!” Andrea cried. “Don’t-- don’t come any closer, please.”
Supergirl stops on a dime. Her gaze darkens. “What did you do?”
“Kryptonite. It was-- you were-- Lena got in the way. She wouldn’t let me hurt you.”
Supergirl stares at Andrea, and then at Lena. “Lena...”
“Was-- right thing-- to do.”
Long fingers brush against Andrea’s side, seeking purchase. Andrea reaches down and takes them in her own, holding them tightly.
“Go with her,” Lena grinds out. “When I’m--”
“Lena, no...”
“She can-- help you.”
“So can you! Lena, so can you, I need you, okay? Just stay with me. Just stay...”
Lena’s fingers go limp, and the laborious rasps for breath cease, pitching the lab into eerie silence.
“Lena...” Supergirl collapsed to her knees, reaching.
Lines of green burrowed under the hero’s skin, pulsing ominously, but Supergirl didn’t seem to care. She scooped Lena out of Andrea’s arms, and held her close.
“I’m sorry, Lena. I’m so sorry.”
Andrea didn’t know who the words came from: herself or Supergirl. It didn’t matter. Nothing mattered.
Not anymore.
