Ellie's never imagined Abby laughing much, but she's heard it a handful of times now and she's always so blown away but how easy it sounds.

Like she laughs a lot. Like she smiles, enjoys it, tells jokes.

It's always been fascinating in a distant way, the way Ellie studies space. Like Abby is an entity of the universe, some churning black hole and not a person, but... now she is. She's becoming one. Slowly, but surely.

It feels like the universe is literally having to shift to accommodate it, all right.

"Time to head up?"
