important things:
how often kate makes a point to say “thank you” to juliet because she notices early on that no one ever does. people take her for granted and even before kate likes her, she doesn’t like that. she is willing to sacrifice some of her carefully cultivated Toughness to make sure that juliet knows she is there, that she SEES her. how kate is literally the only reason that juliet doesn’t die alone; how she is the only one who doesn’t give up hope that she is still alive.
how after juliet gets a feel for what kate is like, after she figures out what makes her tick, she makes a point to be softer. she, too, makes a point to sacrifice some of what she’s built to survive. how when juliet outs sun to jin she’s just like “sorry, i did what i had to do” but when she yells at kate it’s “i’m so sorry i yelled at you”. how juliet is the only one who not only never uses kate’s past / trauma against her (and she knows more than anybody!), but also actively empathizes with her and tries to make amends when she does something she knows is triggering.
how they never fight over a dude. ever. i say this a lot when i talk about them because it is So Rare and i so expected it to be different but. i can’t say it enough. they are better than that. these are two women who have, in their own ways, dedicated their lives to helping other women and they are not here for that. how they will support each other no matter what or who is between them.
