"Astrid," Olivia says, long fingers reaching to catch Astrid's hand in her own, "you know we'd be lost without you."
Astrid blinks against the sudden hot sting at the back of her eyes. She knows Olivia doesn't touch people casually; paralinguistic signals are language too. The gesture means the world, and it makes her more determined than ever not to disappoint the trust of this brilliant, private woman who carries the fate of universes on her capable shoulders.
It's not Olivia's burden to bear alone, not any more. "I'm always here if you need me," Astrid replies, and squeezes back.
